It varies from car to car. but around 220 degrees. Noting that all cars do not have an accurate temperture reading at the guage, per manufacturer

It should click on about 180 degrees to 200.anything over that you should watch. Car;s can run up higher due to the thermostat, or the temperature sender switch. Their's a secondary fan for the A/C which if you see the temperature raising into the red zone, you could put on the A/C and the fan will click on for the A/C.

SS w/3.8l engine. What would cause the first electric fan not run but when temp rises the second fan will come on?


The coolant fan should kick on when temp reaches 192 degrees. Have you changed your thermostat? The 2nd fan is for the a/c. If car is running hot, it's probably thermostat or cooling fan

I have a 02 Grand caravan that has new radiator, termostat, one new fan. the temp gauge goes up to max hot the drops right back down in seconds. what could be the problem?


it could be you have an air lock in the cooling system
remove the rad cap from the rad, start the engine and let it run until the coolant drops (add to fill it back up) or until the coolant boils out of the rad spout.

maybe pull the heat sensor. -replace it OR clean it off, reinstall it.

Why does my audi tt temp. gauge go hotter than engine temp. fans work changed thermosat , temp sensor ,and water is ok ?


Hi
i suppose i have to ask how it is that you know these temperatures are different?
is the car actually overheating?
Have you had it scanned for any fault codes?
You may have a defective temp guage...check it by removing the sender plug and see if the guage falls totally to zero...earth the guage wire and see if the guage goes to max.

Thermostat


hello,
first thing to do is open the radiator cap (when cold) if you have one, other wise look in the recovery bottle and make sure that it is half full of coolant. if full, start the engine and let the engine warm up to normal temp the heater on and on max temp and max fan control. watch the temp gauge and make sure the temp goes to the normal operating area and does not overheat the engine. if temp is ok and you have heat that is hot as normal then everything is ok.if no heat and temp is to high then thermostat maybe bad? if engine temp is ok and no heat then you may have blockage in the heater core and or hoses

VAUXHALL MERIVA COOLING FAN


Change the relay, situated in a black plastic box up in front of the battery. Costs about 7 pounds / 11 dollars USD on ebay and takes 30 seconds to do. Until you get it fixed, protect the engine when temp get over, say, 90 degrees celcius, by opening up your side dash vents, turn the in-car fan on max and the temp up to max. The hot air will go directly out the windows and you will see the temp gauge drop back to about 80 degrees. I did this for a year until I figured out the relay needed replacing.

Air conditioner goes off when fan speed is increased


when it's on 'auto', the fan adjusts according to the temp in the car and the temp setting you have it set at. try setting the auto temp control down to 65, then hit the "-" one more time to send it to "LO" - the fan should automatically jump up to max.
