GAZZUZZ, got my very first overheating problem. It looks electrical. The car has been throwing one problem or the other.

This evening returning from work, i just had a dash with another car but to my amazement something quite out of place happened. Fuel needle was very very low but the other needle was above half, i was shocked.

I stopped, popped the hood, with engine still running, a small coolant pipe leading to cold start portion of the throttle body was hissing vapour and has splashed my very old green coolant that has never been drained. I can see coolant all over but no fan blowing nat that high temp. I turned off the engine and returned ignition to on (II). Turned the AC on (engine off) and fans came on. Turned it back off. Started the car and let it idle for more than 5mins while i connected my bluetooth OBD II device. Coolant temp show 113 degrees celsius but no fans. I topped the coolant reservoir with water and drove home blasting full AC as temp dropped to steady 104-105.

Got home and swapped fan relay but no difference on idle. All fan fuse are intact. Note AC blower fuse is ok since AC is blowing.

I have read about fan switch on thermostat housing but cant find any switch there. Am lost now please help.

Uncle ejoor, wat if the tires in the same car are not the same size? Does it av any effect on the speed? Or let's say u have 19" at the rear and 16" front? Because from ur explanations 19" tires can overtake 16" tires fixed in the same car.

Brilliant question.

Only drive wheels will be affected. So, if a car is front wheel drive and you change front tire size, speedometer will be affected. Same as rear wheel drive. But if a car is 4 wheel drive, it gets more complicated. Same as if one tire size is different with the other. The speedometer may not be affected but the differential will be affected.

The differential is what causes only one tire to spin at different speed from the other. It is a fact that when a car is traveling in a circle or turning, the tires in the inner circle travels shorter distance than the outer tires. So tires normally must not be at the same speed all the time, differential takes care of that problem.

So technically, if one drive wheel is bigger than the other the differential assumes the car is turning a circle or one tire is slipping in mud and it allows the bigger tire to be faster than the smaller while the speedometer is not affected. However, the differential will constantly be overworked and possibilty of transmission failure is higher.

A front wheel drive has 1 differential a rear wheel drive also has 1 differential. 4 wheel drive has atleast 3 differentials. So a 4wd having different tires is a very complicated. A 4wd has differential for the front axle, back axle and center differential. The center differential will cause the front axle speed to be different from rear axle speed.

Thats one out of 2 reasons why it is bad to but different sized tire in front or back.

1 pack of clips for Grill, bumper and missing ones on the splash sheild under fender.

There are 2 types of these pins i have noticed. I hope u noticed too. There are long ones with flat edges and short ones with curved edges(not screw type o). The short ones grips better unlike the long one in your hand.

Especially for that splash shield, you better get the short ones else your splash shield will soon be wasted. My friend lost his slash shield due to the long ones pulling out anyhow.

Oga Gassus, those mallam's really try for your fingernails.

Na wa o, see detailing.

banky3w:
Bros no vex naa....... I am a novice and was only seeking knowledge...... I think the only engine /tranny combo I can recognise straight up is Toyota Camry 1998-2002. No vex...... I'm a learner.

No wahala.

banky3w:
Who are you quoting precisely? No add to my sorrow oh..... Mind yourself in advance.

You!!!

Is it not you who is asking whether GAZZUZZ bought engine/tranny?

The pic I showed you clearly shows the transmission and you are asking a very irrelevant question. Even the pic GAZZUZZ posted as the engine was brought down from the container showed the transmission attached but you wouldnt see it yet you are asking questions. I thought i was helping you but clearly GAZZUZZ was right not to have answered your obvious question.

banky3w:
Haba Bros don't be mean naa...... I saw you quoted Engine /tranny and you only showed us you bought engine..... No qualms sha...... I still loyal.
The only thing I noticed with Honda was that it seems balanced/heavy on speed than Camry....... I have done above 180km/h on both...... The experts are taking away my love for Toyota....... I know Honda beats Toyota in interior designs but....... The only Honda I love is the Crosstour and I don't have the money yet....

Bros look at this again, what do you see?

I am am here clapping my hands for you and will definitely show the thread to my friend who never cares about his car.

One advice though, pls keep those headlights you removed. I have a hunch you will fall back to them in the next 1 year when these new ones change colour.

ugreat:
Where did u get wet batteries, as most dealers claim they dont sell wet batteries?

99% of car batteries in the Nigerian market today are sealed maintenance free wet cell batteries. Bottom line is that it still a wet cell battery.

I searched for the old school wet cell battery but couldnt find any.

nurey:
If nah me say make you come rebuild my engine wey he knock for 300km/h doing a drag race with bugatti , you go say my car don old abi? Kontunu, there is God ooooh

LOL.

If na me carry this car come GAZZUZZ shop say make him rebuild na plenty story him go give o.

But am bookin my space on this thread hoping justice will be done to this car in the master's own hands.

I jealous you o, GAZZUZZ.

eluquenson:
That means these guys are misleading me to paying such amount.
Thanks for the info.

GAZZUZZ:
Failing Abs wheel speed sensor. A scan showing a coherence fault would indicate a faulty pulsar, but a scan showing an open or closed circuit would indicate a damaged abs sensor or harness. I am sure you do not have a scanner with you, so let's diagnose old sch.

Get a multimeter, set to read resistance, set to kilo ohms, working abs sensor for your vehicle would be around 1500k now disconnect abs sensor at connector get a firm reading, then wiggle the harness leading to the tip (2 man job) do it for all 4 sensors and if you do not have variations in resistance readings, problem is with pulsar and you will need a scanner to narrow that down the easy way.

I'm putting my money on a faulty abs sensor. Most technicians are careless around them when working.


P.S, we were wrong about the K24AZ3 and the 2 solenoids and 2 pressure switches, I am buying one tomorrow and it comes with 1 switch and solenoid, so are over 6 I saw in the warehouse. More pics after I pay for it.

My digital multimeter is missing but will get one from one of my electrician boys. I will have time for this on Monday.

I was able to remove the stuck front left ABS with hydraulic this morning. Cleaning it didnt help, by the time i reversed to gate the ABS showed. After restarting, no ABS till i got to work 30miles away. I felt the ABS kicking in just once but briefly.

I was considering a scan when i get time but the guys dont let you be incharge of your own scan feeling they know better. They usually end up just telling you the code and have no idea what it means.

About K24Z3, your comment stroke a memory when buying my friends Z3 engine. At the point of buying i didnt know the difference so i paid less attention to the sensor but can remember vividly that the Z3 we got had only 2 connectors, 1 solenoid and 1 oil switch. But my friends sensor has 4, 2 solenoid and 2 oil swtiches. So we couldnt use the sensor on the new engine. We used the sensor from the old engine. Before exchanging the sensors, we confirmed that both engines had exactly the same oil ports on the sensor location.

Its confusing on why some cars will have the 2 and others 4 connectors.

Gazzuzz sir, i also have a problem to share.

I had to park my car for a week for the issue of power steering pump pipe leakage problem. I didnt travel with it for fear it will become worst and might not get me to destination. I couldnt get a good and affordable replacement so i asked my mechanic to do the working he did on my mum's 1996 accord.

He did it and it is working well. The brakes felt spongy so I instructed him to bleed the brakes. All 4s where bled.

This brought a new problem, everytime i reverse, ABS light comes on but goes off at restart. When moving on asphalt without touching the brakes i hear the ABS pump working intermittently and sometimes during soft braking. It does that more in the mornings and ABS light comes on thereafter and sometimes doesnt.

I thought the brake fluid was short but it has been topped with no difference. My drivers side ABS sensor wire had cut before and was joined and taped with electrical insulating tape. I checked the joint its still intact with no contacts.

Suggestions i got from search is to wipe clean all sensors and hub teething. I couldnt get the sensor out as its kinda stuck on.

Whats your suggestions.

erico2k2:
well I have been at work hence my very brief and short reply now Im home
I have read fru your quotes and that of crowly.I dont know how new your own car is so i cant say but Im going to use my car as an example and how its system works hope it thrwos more l ight into the VSS relative to it uses.
Now my car is a 2012 Range Rover sport Autobiography so comes fully loaded this is how the VSS works
Now the Variable Assist Power Steering (VAPS) system uses Vehicle Speed Sensor (VSS) input to regulate power steering pressures for higher assist at slow speeds, making parking lot maneuvers easier to perform. Honda does that by a pressure switch mounted on the pressure line between pump and steering rack. The switch senses a drop in pressure as you attempt to turn the steering at slow speeds, the ECM raises the idle speed. The system works better on cars equiped with electric trottle. The Anti-Lock Brake System (ABS) uses VSS information to determine when a wheel is locked up and releases pressure to that wheel to maintain directional stability. Some vehicles use separate sensors for the ABS, but it is common that the computer uses the information from the wheel sensors to act as a VSS. In my opinion, ABS uses both Wheel Speed Sensor and Vehicle speed sensor. Each wheel speed is compared to the vehicle speed and anyone short of the set threshold is considered locked. The ABS module kicks in. For example, many newer Ford vehicles use a rear axle mounted speed sensor for both ABS and computer related vehicle speed functions. Instrument Cluster (IC) and Hybrid Electric Cluster (HEC) modules use vehicle speed info for speedometer operation.I have a 2004 jeep liberty in Nigeria this is waht it uses as shown on that pic.
The vast majority newer Vehicle Speed Sensors are of the permanent magnet type, and function much the same as a CPS sensor. The sensors can be mounted either in the transmission case (like yours) or rear differential assembly(Jeep and Ford). Those in the transmission are typicaly gear driven, and those in the differential function by using a trigger wheel mounted with the ring gear. Both style sensors perform the same task.
I hope this is more clearer

Very clear and well written.

Just to add. (Letters in red)

erico2k2:
Those are your abs sensors . The share same build as the speed sensors . Your speed sensor must be at tour axle or end of ur drive shaft .

Vehicle speed sensor is located in the transmission. Vehicle speed sensors are usually located at the transmission while wheel speed sensor is at the wheel.

Speedometer uses that of transmission (VSS).

ABS uses both (WSS and VSS)

Vehicle Stability Assist uses both too.

If either VSS or WSS goes bad, ABS and VSA stops working. If WSS goes bad speedometer is not affected.

erico2k2:
wrong it is.chk ur car it has anti skidding device fitted

My car has this sensor on all wheels. My car has ABS but not VSS.

Unplug one wheel connector and the ABS light illuminates but speedometer still works. My friends car has both VSS and ABS, one of the wheel speed sensor wire broke and both VSS and ABS illuminated. He drove the car for months and speedometer never stopped or misbehaved.

My car has nothing like anti skidding device. Note, VSS is the anti skidding device but my car does have it while it has the sensor he shared.

crowley:
Even if he switch tyres, the car would detect it, and calibrated your readings accordingly. thats what i have been trying to explain to him. its part of one of the Functions of the custom speedlimiter installed by the company. your car knws whatever u do.

If i smoke cigarette in my car, will my car know and open the windows for some fresh air?

I just wonder what system detects tire size.

TPMS measures tire pressure, what measures tire size?

Conner44:
It depends on exactly where the speedlimiter is placed and the kind of car.

Also your car can't know everything that you do to it in terms of aftermarket upgrades that's why all cars come with manuals and factory recommended settings which they really don't want users altering.

Imagine I installed monster truck tyres on a regular VW beetle do you think it would know and recalibrate it's speedometer accordingly?

True.

Using a monster tire on a VW beetle does not only requires recalibration of speedometer but the entire car.

crowley:
Have you programmed a car before?

I havent neither do i know how.

crowley:
and you must have heard abt the VSS right?

This speed sensor is used by ABS and Vehicle stability system and cannot be used by the speedometer. The reason a speedometer cannot use it is because this sensor will report speed of individual wheels as against speed of the car. Imagine one tire losing complete traction and spinning freely and speedometer reading speed of one tire as car speed but car is stationary.

crowley:
so therefore logically since a car with a larger wheel will cover more distance in fewer circles, there d mentality of larger wheels going at 100km/h will cover more distance that a smaller wheel going at 100km/h. But thats nt d case bcuz larger wheels will read slower than smaller wheels. so time it will take a large wheel to read 100km/h, a smaller wheel wud read 130km/h covering d same distance. so a constant is derived 4rm d wheel rotatin ratio which is then programmed to the car. 16" 17" 18" 19" wheels 4 cars nd 18"-21" for SUVs all have relative speed to the constant distance covered by d wheel. so 19" wheel would adjust its speedometer reading according. hence all reading are made constant irrelevant to wheel size

On the black bolded, larger tires cover more distance per rotation.

On the green text; invert the assertion.

On the red text; LOL, 130km/h cannot be same as 100km/hr

Your whole post needs review.

Pls watch the videos shared by ZIMDRILL.

Also make research on google like this famous site shown below.

crowley:
pls check the mechanism of a car speedometer b4 mentioning me. am a robotics and automation student, so believe me, thats my field. lemme break it down. Speedometer relies on the wheels. that part u got right. but they are calculated by each complete circle. small magnets attached to the cars drive shaft triggers a magnectic sensor which is stationary which sends electric pulse to d speedometer therefor conveted to speed. so each time the wheels completes a circle, the magnet triggers d sensor on each pass. the faster d wheel rotates, d faster the pulse are received. nd u should knw smaller wheels completes full circles faster nd covers less distance, nd larger covers more distance but longer time to complete a circle.

I totally and 100% agree with you.

However, there are 2 things you have failed to take into account. Location of the sensor and the speedometer calibration? I wont bore you as an automotive engr in training, please look it up and inculcate in your theories.

Yes the sensor reads rotation, but is the speed sensor on the tires? Where is it usually located? Usually the transmission. So, how will the sensor know how many kilometers the tire has covered in one revolution of the transmission output? It will never know unless its calibrated to know. The calibration is the size of the tire as a constant.

crowley:
My dear tyre does nt affect speedometer. weda a catapiller tyre or a wheelbarrow tyre. do planes nd choppers use tyre on the air? but they have speedometers. so 4 fu€k sake, what d hell are u saying.

Tire size does affect speedometer.

Planes and choppers dont measure speed the same way like cars.

Cars measure the distance covered by car with time while planes measure pressure of the air around the plane. That is why km/h is not the same as knots. You've heard air speed before.

1knot is 1.852km/h.

A lot of guys wont still agree to it. Anyway, its a fact, its left for the open mind to understand.

erico2k2:
How does 2 and 3 you quoted constitute a question?

1. Are you trolling me?

2. I believe you are trolling me.

3. You have been trolling me

From the 3 sentences above, would you reply only to 1 and forget about 2 and 3 because both doesnot have a question mark?

Anyways, am tired of it cause no matter how i try to explain, you either refuse understanding it, counter it or deliberatly move on to another matter. All has led us to nowhere so its pointless replying you. Done.

Lastly, if this is the only question

Can a car going at the speed of for instance 120km/ph overtake another car doing the same speed?

you deem fit for an answer, my answer is NO.

Hope you are happy now and would stay off my back with regards this 1 year old matter.

erico2k2:
erm I think you should check page one as i did, the OP asked just one question.And the answer to that is NO.

Can a car going at the speed of for instance 1ph overtake ano20km/t car doingher the same speed? I have argued about this on several occasions, because I believe the speed clock or odometer should be like a clock that's always accurate and no clock goes faster than others.
I know car engine, horsepower and capabilities differ. But then I believe a car going at the same speed can't overtake the other.
If I am doing 120 km/hr for another car to overtake me it must be doing at least 125 or 130, car gurus in the house please help.

I have several times and have quoted it a few times even on this very last page of the thread. I quoted the op in my last reply to you.

Question: 1

ableguy:
Can a car going at the speed of for instance 120km/ph overtake another car doing the same speed?

Answer: No (all conditions being equal)

Question 2

I have argued about this on several occasions, because I believe the speed clock or odometer should be like a clock that's always accurate and no clock goes faster than others.

Answer: False believe (because blah blah blah....)

Question 3

I know car engine, horsepower and capabilities differ. But then I believe a car going at the same speed can't overtake the other.
If I am doing 120 km/hr for another car to overtake me it must be doing at least 125 or 130, car gurus in the house please help.

Answer: True (all things being equal)

Substitute all the blah blah blah blah with what i have being saying since last year which you wish i didnt talk about. All those arguments were geared towards clarifying the op's believe, whether its a question or not, giving him an opinion is like giving an answer to the question even if it does not come with a question mark.

erico2k2:
In your own book, how would you go and carry out this experiment,Im talking from my level of understanding and education, so I will like to think once again we are on same level of reasoning however if I have to come back to remind you a third device to measure the speed of both moving cars at same time then I stop to think of the whole benefit of this conversation.

There is a simple and single answer to OPs question which is NO
REASONS
1 both cars have same speed as stated by op(speedometer Tyre or shape bears no significance here)
2 speed would be constant cos OP said same speed.
However if the question was if we change/modify a part of a car if speed will be same then answer might be NO

You mean to say questions. I found 3 questions and i have different answers to each of them.

If you mean to say your level of understanding limits your understanding points i rainsed, you should not critisize what you dont understand.

Did the op ask only 1 question? I really need this answer from you. You seem to only focus on the first sentence made by op and neglect the rest of his post. What is your answer to the others?

1 is a yes/no question
2 is a right/wrong question
3 is a yes/no question

Question 1 is the same as question 3 but the 1 is NO and 3 is YES. The difference is in the sentence construction of the op. So you cant answer the op by just saying one big yes or no.

I have learnt alot on Nailand especially Cartalk, i wont hesitate to put it more answer than i am being asked. You should not stop me from doing so but critisize the wrong things i post and add to the right ones. Why should i say yes or no and walk away when the yes or no has assumptions attached to them which can change the answer in certain conditions. You want me to "automatically" assume conditions i know exist but pretend it doesnt.

From my understanding, its either you say;

yes/no (all things being equal)
Or
Yes/no (explain)

I chose the later but you want to force me to say the former. When both answers are correct. What are we talking about here.

erico2k2:
when the OP said two cars automatically it should come to mind we need one device to measure both cars so the speedometer, car engine, Tyre and its size should not be a factor in the derivation of that narrative of speed in this context.
So in contrast if two car are traveling at same speed measured by a speed gun, one cannot overtake the other or get from A to B faster that the other.This is the simple fact we are trying to deduce.No need to derv into speedometer, for all we know the speedometer of one of the cars might very well not be working but thats not o ne of the determinant of the said experiment if it get conducted.

If you say automatically, that means an assumption. In science when you make an assumption you should state it.

When you and your friend compete with each other, which same device would you use to accurately compare your speed without introducing a 3rd external device. Why cant i tell you the complications.

Did the op delve into speedometer or not?

I can count atleast 3 issues, why do you expect me to answer a single yes or no for all 3 issues.

If i say NO to the words in green, is it the same for the words in black or in red?

Is it every speedometer that is "always accurate"?

When you change tires, will your speedometer be "always accurate"?

This ops post didnt ask for a yes or no answer.

erico2k2:
If we are going to conduct this experiment on two different cars on a race track wont we measure the speed at same time with one equipment?

Yes. One external device eg speed gun, GPS etc but not the speedometer. A speedometer mounted on cars have a low degree of accuracy.

Any device is as good as its level of accuracy. A ruler measures linear dimensions, likewise a venier caliper or a micrometer screw guage. They all have their level of accuracy for measuring the same thing.

A speedometer will be as bad as a ruler measuring inear distance of less than 1mm.

Example, measuring thickness of my phone with 3 of the mentioned devices will give results as such. Ruler 9mm, venier caliper 8.92mm, micrometer screw guage 8.9123. The difference between the 1st and last is 0.0877 which is significant.

In the same vein, a car speedometer is not as accurate as a radar or laser speed gun or the GPS speedometer. A car speedometer may say 100km/h but the radar or laser could be more precise say 98.35km/h. If you measure one car with its speedometer and the other from a speed gun. They may not be in the same speed and with time one car can overtake the other.

ableguy:
Tell them ooo, they're just making the whole thing more confusing

Whats wrong in saying the answer is no but that no is dependent on conditions.

My car and your car travelling at 100km by reading at our speedmeters may or may not be same speed if errors are not eliminated.

It doesnt change the fact that the main answer is no.

If you are a science student you must have heard of real depth or apparent depth. Its like looking at the bottom of a swimming pool full of water. The bottom looks 1m (apparent) but the real depth is 2m. Same with measuring speed with speedometer.

All this talk talk i gave doesnt change my initial simple answer that its a no.

From the main question

Can a car going at the speed of for instance 120km/ph overtake another car doing the same speed? No I have argued about this on several occasions, because I believe the speed clock or odometer should be like a clock that's always accurate and no clock goes faster than others. wrong
I know car engine, horsepower and capabilities differ. But then I believe a car going at the same speed can't overtake the other. Theoretically true but practically complicated
If I am doing 120 km/hr for another car to overtake me it must be doing at least 125 or 130, car gurus in the house please help.

You see, the op asked several questions and cannot be answered with a simple yes or no.

purespikes:
Thanks immensely, God bless. As explained in my post, i want to know if i should continue using the engine or i should change to the z3, since i don't want damages on other parts like transmission and all that. Like i said, the engine is doing fine only that it does not rev up as fast as i expect. one it picks, it runs good. thanks again

If you have money to waste, you can go ahead with replacing it. I cant imagine any damage to any other component by this engine. It will never give you the Z3 feel if thats what you want to hear.

If you want to sell the Z2 i think my friend would consider buying from you if its affordable which will be far better than you will get from any engine seller.
