Me think your car runs perfectly ok

ndidibabe:
Please I need urgent advise on this. I just bought the Lexus and it is not up to 3 months. Due to my experience with my old Camry muscle, I am very careful not to get the new car into any overheating mess.

When I start the car early in the morning, in an idle state and turn on the AC, the radiation fan does not spin. I think it should spin immediately the AC is turned on.

If I leave the car idle for thirty minutes and the temperature is even above the half guage, the radiator fan will still not spin.

However, when I drive around, the fan picks and works normally. Spins for a while and cut...

At this point, if I put on the AC, the fan spins but never cut until the AC is turned off.

I am afraid to visit my kazeem even though he is a bit learned and uses diagnostic tools. I call him Kazeem because he advised I remove the thermostat of my old muscle and connect the fan direct which I believe it's what killed the muscle.

Kindly advise.

ndidibabe:
But isn't the fan suppose to spin when AC is turned on even if it is idling? Then, should the fan continuously work when AC is turned on?

Kazeem has brainwashed you.

Start patronizing Gazzuzz...

He'll tell you the real deal

your vehicle is a smart one. there is a module in charge of controlling the AC system. kindly carry out a system scan to see if there is any stored codes.
also a simple visual inspection will really help. check the wiring of the fan and other related systems.
also kindly note not all vehicles act the same way. for some vehicles, the AC fan will never be turned on by the AC module if the whether is cold enough. in some it will. i have a feeling your AC might be working as it should. however get it checked (not scatter scatter o) by a competent technician...

ndidibabe:
So in your own car, the fan does not start spinning when you put on the AC?

Congratulations. What is vehicles present mileage vs mileage when it was exported ?

This answer will most likely resolve the next quote




Under no circumstances should vehicle temp exceed the half mark, unless there is a defect in the cooling system which I am assuming there is not, and that takes me back to the first quote about mileage.

In Nigeria 9/10 vehicles have had their mileages rolled back (BCD tins) how this is done in most cases is to take out the instrument cluster do some quick reprogramming and presto 500k miles becomes 25k. Sadly the cows that do the actual work are usually sloppy and don't return dials to the factory rest positions which I turn could result in first quote. There are several quick ways to confirm if it is a defect.

1. Crude method . Start the engine (AC off) Open the bonnet and watch the temp go up, the second the fans start working check the needle, if it is over the half mark, then the temp dial is wrongly placed.

2. Technical way. Plug a scan tool and leave it on live scan, start car with a/c off search for coolant temp in scan tool, when the needle goes above half in vehicle , compare data in scan tool, if over 100deg Celcius, then there is a problem, if it's relaxing between 90-98deg Celcius you are fine and again the temp dial is wrongly placed.


How does this all work.

The cooling system of your car has computer that monitors engine temp (among other things) the mechanical thermostat opens up at about 86degrees Celcius and allows hot coolant flow from the engine to the radiator, the fans don't kick in till about 96degrees (low speed) and stay on till the temp drops to 89degrees then the cycle repeats with the coolant in the radiator dropping to temps lower than the engine coolant temp which shuts the mechanical thermostat up waiting for engine temps to heat up an the cycle continues.

It does when the engine gets hot....

Your car is in factory settings...not in "Kazeem" settings


Be grateful coz that settings is like you have a virgin car...if Kazeem touches it...it has been deflowered

Many thanks for this analysis sir. Mileage is 114k.

sultaan:
E350 with 114k miles is still young.
Everything works but you think they don't when they are supposed to, Like said they system is programmed to data set points you can read with scan tool. Don't go mess up your car because you think. You have to know exactly how it is set up

your car before it was shipped to naija was used in a very cold region , tell your mechanic to remove the thermostat , permanent the fans and also check the polarity of the fan (the temperature gauge will never go beyond that normal position ).

Oga,as regards your 3rd paragraph,normal operating temperature of Mercedes W204 is well above the half mark,just below the 3rd quarter mark.
You might need to do a bit of research on this.
