To all the auto personals and experience people in the house this question is for you.

Topping of engine oil in the car after noticing shortage due to some justifiable reasons like maybe, shortage due to damage and or replace oil seal, due or about to be due for a total change of oil/service, etc.

So does adding of a fresh oil to top the engine oil good for the engine?

What is the likely advance effect of rhis usual act?

And all other G.Os in the house.

I wish Dru23 were here to contribute to this as well.

You're take please.

The only adverse effect is when you pour your Engine oil in the system when the Engine is at threshold temperature. It can cause crack within the engine block.

So do it early in the morning before you crank. Hope I have answered your question sir?

Anti-Theft

I want to share an experience with you, I was to supervise the changing of Windshield for a customer yesterday, Hyundai Sonata 2011 Model. I drove the car down to Ladipo, the process of changing started with no issues whatsoever, After about one hour the changing was over and was about to leave when the car refuses to come to live.

The coming to live was not just cranking, but the car refuses to to even show Dashboard light, the only thing working was the horn. I was thinking it was the battery and guess what with all the batteries, the car didn't bulge.

So I called the owner to explain and was expect a threat from him and all, but he was calm and even was trying to proffer solutions to it.
At the end I resolve to calling a programmer to reprogram the car security system after concluding the car actually went into locked down mode.

So the reason I putting this forward was because I want you all to learn and understand the work of your anti theft system, the car went into lock down mode just because it detects a break-in from the windshield changing.

Always I repeat make sure you remove the battery if you are performing any major work on cars that the system is hyper sensitive.

Thank you

autologic:
Method of removing the battery terminal to test the alternator is very crude and not a standard method and accurate method of testing alternator even some cars model will even go off with terminal removed and doesn't imply that alternator is faulty moreso u can destroy sensitive modules and accessories especially if u are working with late model cars laced with communication network . There are many recommended method and more accurate way of testing alternator without removing battery terminal,I will advise to check them up online .

Good day sir/ma I really appreciate the heads up. The method is crude and it was carried out specifically for the purpose of the brand and model. In other cars code like generator circuit below threshold pops up on scanning tools.

Thanks boss

olawale360:
I have some issues with my RX 300 last month. Whenever I'm driving and the engine becomes hot, I do hear a sound like a ticking sound which makes it difficult to move.The temperature is a little bit above average. I ran a diagnosis and I was told to replace the two knock sensor and two 02 sensors. He said each sensors cost 7.5k each (30k). Last week a friend heard the sound and told me he had a similar issue with his Lexus too. His mechanic told me its a faulty thermostat and it has to be removed and connected the two fans directly, so it can start cooling the engine whenever I start the car. The car is working fine now, no more sound, moves very well and the temperature is back to normal.

I hope there won't be implications for the changes made? Thanks

Boss first and foremost never try that idea of Kazeem again, your thermostat is very important to your engine and it save the lifespan of the Engine. Now the cause of the overheating is not resolved yet and you re gradually killing the engine. So boss I will advice you spend to prevent great loss. I can tell you very soon you will experience flat gasket and spend more to keep the engine now

For more details chat me up sir

What is ABS Wheel Speed Sensor?

An ABS wheel speed sensor counts wheel revolutions. It reads the wheel rotation and measures it in revolutions per minute (RPMs). It should not be confused with the gauge on the dashboard that displays the engine RPM via the tachometer. 


Common Causes Of A Bad/Failing ABS Wheel Speed Sensor

° Dirt at the tip of the wheel Speed sensor.

ABS Sensor Defective

Loose or broken ABS wheel speed sensor wire

Defective ABS relay or a blown fuse

Bad ABS Module

Burned ABS motor

Damaged wires

Low battery voltage

One or more wheel speed sensors (ABS sensors) may fail to render the ABS inoperable and triggering multiple warning lights on the dashboard. Some things that you may notice are:

ABS system disabled, as well as disabled electronic stability control (ESC) or traction control systems, if the vehicle is equipped with them, as these systems rely on the same sensors as the ABS system.

ABS warning light illuminated on the dashboard.

Occasionally, the speedometer will stop working and the check engine light will illuminate


Symptoms Of A Bad Wheel Speed Sensor

The first symptom is the Check Engine light coming up on your Dashboard, followed by

Traction Control Light On

Stability Control Light On

Transmission Won't Shift Gears

Vehicle in Limp Mode

Note: Run a proper diagnosis on your ABS Wheel Speed Sensor to know if one or more of the Sensor is affected or if the wire or connector needs correcting.

How can I calculate fuel usage considering that toyota camry 2003 is expected to use 21/30 MPG (Miles per gallo) for city/highway drive.
Knowing that we use liters/kilometer in Nigeria

Calculate with this
1 gallon is equivalent to 3.7 or approximately 4 litres
1 mile is equivalent to 1.609 kilometer

glambo:
Good day
Please help with this.

Noticed this crack while mechanic was pouring engine oil some months ago.
What is the possible effect of this on the car and what could have caused it.
Bought the car a year ago as tokunbo from US.
Having being using hardex engine oil since I bought the car.
The car is a Toyota Camry 2003.
I can't say if this came with the car when I bought it.

Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.

So I believe before your car got to you it has been in a very cold region where the crack first happened, so boss if you don't mind to know the full extent of the damage you can bring it over to open the top to access the damaged and removing the sump to check for metal shavings...

Hello please i just got a 2015 Lexus RX 350 tokunbo it had a slight hit on the bumper in the USA which was repaired here in Naija, the front parking sensors needs to be fixed as well as some other check lights showing up , where can i take this vehicle to to have it all fixed by a good engineer thanks

Bring it down to my workshop sir

Boss, any possible causes of engine oil shortage? No visible leakages and the engine is not smoking...

If no visible leakages and doesn't smoke

I will suggest to check the kind of oil you are using sir, if too light for your engine.
And another possible cause is crankshaft seal, are kind of tricky, they may not leak while on standstill but spill when on motion.
Another scenerio can be your piston and rings, it may not smoke at the alarming rate but is gradually giving up.
Just proper diagnosis should help you sir

Torque Converter Clutch Circuit Electrical

Description
OBD-II Trouble Code Description for P0743 Hyundai
Torque Converter Clutch Circuit Electrical

What does this mean?
OBD2 Code P0743 Hyundai definition:

The Torque Converter Clutch (TCC) solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter. Lock-up operation, however, is prohibited when A/T fluid temperature is too low. When the accelerator pedal is depressed (less than 2/ in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

Symptoms
Possible sumptoms of OBD code P0743 Hyundai

– Engine Light ON (or Service Engine Soon Warning
Light)

--- Overheating of the the transmission system

--- No shifting at high speed


Causes
Possible causes of OBD code P0743 Hyundai
– Faulty torque converter clutch solenoid valve
– Torque converter clutch solenoid valve harness or connectors
– Torque converter clutch solenoid valve circuit is open or shorted
– Low transmission fluid level
– Dirty transmission fluid The Error code is generally activated on detection of the following conditions: By performing a voltage drop test, the ECM detects that the TCC solenoid circuit is open or shorted.

Possible Solutions
--- Replacing the TCC solenoid
--- Checking the harnesses, ground cable or open circuit
--- Changing the tranny fluid
--- Servicing the tranny filter

Bad or Failing Alternator

I just finish working on a customer's car, the customer came with the complaint of rough idling and scanned the car to discover Engine Misfire and Camshaft Position Sensor and I recommended the plugs to be changed and the sensor too.

After the whole repair the car refuse to crank, at first I thought this is a drained battery symptom.
I jump start the car and it was running fine only to act out of curiosity if the battery is the problem or the alternator.
So I removed the negative terminal and the car went off, I jump start and repeat the same procedure few times to be sure of the bad alternator.
So in conclusion the alternator was bad and I advised the customer to get a new one.

So I will give few signs to indicate your alternator is going bad

Symptoms of a Failing Alternator

The indicator light on the dashboard.. Mostly battery sign or Alt sign or Gen sign

Headlights are dim or flickering.

Other electrical failures. ...

Strange noises. ...

Car stalls or has difficulty starting. ...

Battery dies

So when you start experiencing any or all of this symptoms take it to your nearest qualified Auto Technician..

In a situation you have more fuel than air in the combustion chamber it is called RICH MIXTURE.

RICH MIXTURE

A rich mixture is a fuel/air mixture containing an excessive proportion of fuel. A rich mixture may be desirable under certain operating conditions, such as when the engine is under load. A rich mixture provides enough fuel to use up all of the oxygen in the cylinder

While in the situation you have more Air than fuel in the combustion chamber it is called LEAN MIXTURE

LEAN MIXTURE

A lean mixture is a fuel/air mixture containing a relatively low proportion of fuel. A lean mixture can be caused by too little fuel or too much air. Too much oxygen indicates a lean mixture and the need for less fuel.

We are going to be treating the Rich and Lean mixture in out next slide


Now there is one thing that affect your engine and it is called PRE-IGNITION

What is a Pre-Ignition?


The definition of pre-ignition is the ignition of the fuel/air charge prior to the spark plug firing. Pre-ignition caused by some other ignition source such as an overheated spark plug tip, carbon deposits in the combustion chamber and, rarely, a burned exhaust valve; all act as a glow plug to ignite the charge.

Causes of pre-ignition include the following:

Carbon deposits form a heat barrier and can be a contributing factor to pre-ignition. Other causes include: An overheated spark plug (too hot a heat range for the application). Glowing carbon deposits on a hot exhaust valve (which may mean the valve is running too hot because of poor seating, a weak valve spring or insufficient valve lash)

A sharp edge in the combustion chamber or on top of a piston (rounding sharp edges with a grinder can eliminate this cause)

Sharp edges on valves that were reground improperly (not enough margin left on the edges)

A lean fuel mixture

An engine that is running hotter than normal due to a cooling system problem (low coolant level, slipping fan clutch, inoperative electric cooling fan or other cooling system problem)

Auto-ignition of engine oil droplets

Insufficient oil in the engine

Ignition timing too far advanced

Excessive amount of oxygen in the combustion chamber



Pre-ignition and engine knock both sharply increase combustion chamber temperatures. Consequently, either effect increases the likelihood of the other effect occurring, and both can produce similar effects from the operator's perspective, such as rough engine operation or loss of performance due to operational intervention by a powertrain-management computer. For reasons like these, a person not familiarized with the distinction might describe one by the name of the other. Given proper combustion chamber design, pre-ignition can generally be eliminated by proper spark plug selection, proper fuel/air mixture adjustment, and periodic cleaning of the combustion chambers.

From experience you are likely to experience rough idling or vibrating engine. It all depends on a good Technician to differentiate and analyze properly.

Good morning black bishop

I noticed once I put on my car ignition my both fans start spinning even on cold morning and when the AC is off.

I scanned the car and got a code that had to do with engine temperature sensor circuit 2 low. could that be a factor while both fans are always on. This also affects gas mileage

secondly can I have the price for front shocks toks, back brake linning and rear bushings. it's a civic 06

Thanks

The code is P1284 and provable causes are

Low coolant level
Faulty Engine Coolant Temperature Sensor
Stuck or leaking thermostat
Engine Coolant Temperature Sensor harness is open or shorted
Engine Coolant Temperature Sensor circuit poor electrical connection

Another thing to understand here is if your thermostat is still intact?

For the other stuff pls

Power Steering Noise.

For most cars still on power steering pump, you need to read this. Most cars now comes with EPS Electronic Power Steering which eliminates the extra pulley for the belt and extra oil compartment.

Whining from the power steering pump will get louder when turning the steering wheel from side to side and the usual cause is low power steering fluid. The best way to diagnose the other bearing noises is with a mechanic’s stethoscope. Failure to repair any one of the items making a whining sound can result in a vehicle break down. Not only that, but other engine components can be damaged when parts with bearings eventually come apart. So it’s a smart idea to get this kind of problem checked out.
