I am still waiting for the answer whether Nigeria is hotter than the middle east where they use the said oils.

dollarnaira:
You just summarized the whole thread.
True to the above.
I said it too that it is all about temperature of a country or environment. Well, like u said API is d real thing. Most guys are here to sell foreign oil.

Highjayboy:
I'm also experiencing same with my car, it's Camry crystal light, 2001 model Camry... I have replaced the catalyst that was stollen and it's still same thing... I was advice to go see a car electrician... So I'm seeing the electrician tomorrow morning to actually know what the fault is...your contributions are highly welcome...thanks

ZIMDRILL:
You are mixing up things

1 at cold temperature eg in the morning lets say at idle the rev goes up a bit (add more fuel) this to make the engine reach operating temperature very quickly so yes the temperature sensor send signal to ECU to calculate how much to fuel to add but i wouldnt say its an open and close loop because its constantly monitored and changing based on other monitoring sensors

2 the 90-100 degrees doesnt activate your (open loop) the 90 degrees is the best operating temperature for a car which gives you the best performance and efficiency from both fuel per mpgs to also best effective oil temperature though new oil nowadays are multiple grades which at low temperature and high temperature it still give you the same protection

Running your car at below 80 degrees (removing thermostat) thats where you increase carbon deposit as the fuel is being burnt below the most effective operating temperature which is 90 degrees, so along the ECU is getting engine temperature reading thats are below 80 degrees the ECU will increase the air fuel ration because it should get back a 90 degrees signal from the temperature sensor therefore you damage you catalystic converter very quickly

So if the engine operating temperature reaches 90 degrees, the ECU will trim the ration becoz the operating temperature has been reached, all people who driving their cars with no thermostat are actuall running rich and the ECU is adding more fuel to help in increasing the temperature to its operating temperature of which it will never happen becoz the coolant is not being allowed to reach 90 degrees becoz its being constantly being cooled

There's a trick I learnt a long time ago when my cooling fans failed as I was travelling, I just turned on my cars heater put it on full blast brought down the windows and faced the vents out the window, the trip was uncomfortable but temp stayed withing drivable limits. I also had to drop speed to 80km/hr

Baba40:
Very educative thread...
How much will it cost me to return my car to factory setting? My thermostat is present but it was disconnected when my previous engine was having overheating problem

hmm this thermosstat factor is something (neverless am not an auto expert) that i quite dnt get from all angles

But then commonsense shouldn't be far fetched.

If we have to go by the fundamentals of locomotion then we will consider there is piston,cam shaft, open-closed valve.

Then at point A air goes into some cylinder in the engine with the valve A open while valve B is closed which allows the mixture of air and fuel then the explosion that occurs drive the piston to half cycle while the remaining cycles completes when there is a repeation of the same reaction, then we get a complete rotation abi

cuz the cycle has been synchronised; hence the cylinders fires at the right time


Consequently the engine block is a heat conductor as you know and will get hotter to expand (which will kill the engine) at some point if it isn't cooled to lower the temp, then this is where the argument comes in.

Now i dnt see how the temp of an engine body affect the explosion or combustion that goes in the cylinder?? if that's the case u can argue bomb might not produce enough or maximam explosion in winters or cold weather

the same goes with an electric iron; the thermostat there is more of saving energy and help in regulating the iron temp so it doesnt get too hot through the circuit breaker i guess.

then it does seem to me that thermstart on the engine is more of saving electric energy for the car to utilize elsewhere

i have been driving my car without thermostart and without having to deal with high fuel consumption and I'm sure there are lots of other out there

therefore i think taking the thermostart off might be the best way to solve over heating if the need arise!!

Ikayman,

Carburetor sprays fuel according to the position of the Throttle pedal. But Injectors spray fuel according to signals it receives from sensors. Once its not getting a signal from any of the sensors or getting a wrong signal, the normal spray of fuel by injectors will be disrupted.

@Ikay,

Really, weather dosent affect vehicle fuel consumption, as long as the motor thermostat & cooling fan are ok. No matter how cold the weather is, the coolant will never freeze (mixture of antifreeze & water: 50/50). Coolant warms or boils faster than ordinary water. So as soon as you start a car, the coolant will within few mins warm up to engine opreating temperature unlike water. The t-stat ensures that engine remains at operating temperature, whether in cold or hot weather. Without t-stat, coolant will be flowing continously from radiator to engine, & from engine back to radiator & wont allow the coolant to warm to operating temp before flowing back to radiator.

Mind you, without t-stat, if the car stays long (hours) in traffic/hold up, the coolant will become very hot, boiling and wont be able to cool again, since the coolant dosent stay long in radiator for the fan to cool it before flowing back to the engine. As its entering the engine, the explosion going on in the cylinders will increase the hotness of the coolant. No room for cooling. Before you know it "BANG". Your Cylinder head is gone. If you are lucky, it will blow up only the radiator hose for the build up hot steam to escape. If you are very unfortunate, your head gasket will be gone. In most cases, when the head gasket burns, it might flow in water in the cylinders & the water/coolant will wash down/pass the cylinders & enters crankcase/sump. BANG! The whole engine is gone!

miccodb:
ikenna u are correct all the way but i dont agree with you in totality when u say the engine will always run cold. there is never a time when the engine runs cold due to otto cycle in the chambers as u know the qtty of heat that accompanies combustion so i prefer u say the engine would run at a little lower temperature so if this happens then the cylinders are not flooded persay with gas and air because the temperature drop is not so remarkable that will cause the ecu to spray excess fuel like ur painting. if that car consumes notieabbly more fuel than normal then i want to belive there is more to it than just removal of thermostat. if a car runs with thermostat at about 90 degrees celcuis then i can confidently tell u that without thermostat it would still run at about 70 degrees celcuis which is not as cold as u are painting.so i cant agree with u totally on the running cold without thermostat.t-stat was originally meant to combat lower temp running in countries with really low temps and cold regions where liquid is required to remain within the egine walls until it is getting overheated then expelle for fresh one to come in from the radiator which now cools the now hot liquid coolant. bearing this in mind then we can easily see the motive isnt too effective in hot regions like nigeria where average temps soar to around 40 degress in the north. so if u analyse this technically i can guarantee u that as soon as u crank your engine in such temperatures it would take less than a minute for liquids to get heated beyond operating temperatures and ready to be exchanged with that in the radiator. so as u run your engine hotter in such area der comes a coincidence peroid when the thermostat is virtually open all the while and all fans blowing because theres really no weather support for the cooling and liquids in both radiator and around engine walls are operating at optimum temps so the t-stat just remains open and since the width of opening of the t-stat isnt as wide as the whole passge then there is lack of proper scavenging and supply of liquids which may ultyimately lead to overheating. so the most important thing is not just understanding the technology but also understanding what the technology was supposed to combat so u can work around when it fails to suit you.
ultimately ikenna there are times when u may need to tropicalize a car buy removing a thermostat without effect to overall performance. poster should check well abg no be thermostat dey make him car chop fuel. i love this forum. so much knowledge to gain. keep it up all.

kc007:
Can a thermostat work normally, that is opening @ required temperature if coolant temperature sensor is malfuntioning?

VirtIQ:
But my car is honda and manual says

Omotakins:
Thanks. It is a two-fan radiator. Can the problem be the fact that it is a one-cell radiator?

mili3kid:
ofcourse u can always restore the thermostat back.
bt make sure the fan is checked and returned to factory default. most times when they remove the thermostat they also make the fans work automatically weneva d engine is on. this shldnt be so. the fans should only run when the engine is hot and after a while stop and run again... like that.
also pls note if ur car is OBDII compliant kindly scan it. high fuel consumption xould be caused alot of issues. not just the removal of thermostat. in my case i am experiencing it because the catalytic converter was removed.a nd when I scanned it d results pointed to catalytic converter.
so try and get a competent mech tho helo check ur car and find the underlying issue causing the excessive fuel consumption

Ikenna351:
First, you will need to find out the colour of coolant recommended for your car cooling system.

Denc:
Hello all

This product: ABRO engine radiator coolant (long lasting green); is it good for autos?
Would you recommend it??

Kindly respond

treatise:
Hello buddies ! You mean should not use water at all on the radiator? I only buy a can of the common coolant and it to the water once in twelve months. Please advise. Thanks.

Bossmd:
@Mayor Thanks so much for coming to my aid.
Please can I buy bottled water in place of the distilled water?

Also please do you know where I can get Mobil 1 0w-20 or 5w-20 oil in Lagos?

Bossmd:
Please does anybody know where I can get the Toyota Recommended Coolant for my new 2AZ Engine? Also it was advised to mix coolant with distilled water, where will I get distilled water?

GAZZUZZ:
ignore this if your engine has been using mineral oil for a long time.

The engine would have built up protective sludge, that would stop it from burning oil.

In the event that you switch to full synthetic oils, the cleaning agents in the oil will breakdown the sludge, and engine might begin to exhibit oil burn and smoking.

If you did not start with synthetic, and you have been following bad gang for over a year, stick with your bad gang.

I have a Nissan pathfinder 2001 model, 3.5 litres, v6 jeep brought in from new Jersey, pls which engine oil should I use for servicing, and should I also remove the thermostat? Thank you[color=#006600][/color]

Emekayoung:
Wat do i do. My baby boy dries up oil within 2 weeks after servicing. I use mobil XHP 20w 50. Though the engine does not smoke. And i always see vapour coming out of the exhaust tail wen ever i start the car in the morning or wen it's raining. Pls u guys shuld help me out...
