SOURCE: COBALT TEMP GAUGE READS 250 DEGREES BUT ENGINE

Probably the temp gauge itself. Most of the time it doesn't have a problem but sometimes they do go bad. Did the car ever overheat prior to changing the solenoid?

The P0218 Code is primarily intended to indicate a faulty thermostat.
Have the thermostat replaced

Other possible causes that could trigger this code would be:
Low engine coolant level
faulty cooling fan
faulty coolant temperature sensor
faulty intake air temperature sensor

SOURCE: Overheats while Idling.

there are 3 cooling fan reays in a 98 aurora and they are computer controlled. the low speed fan relay should turn on when the ecu detects a temp of 229 degrees and should turn off when the temp has dropped to 216 degrees. it is best to check the temp with a computer monitor so you can see what the computer is reading. If you turn the a/c on you can see if the fans are operating. If they don't come on with the a/c you may have a problem with the high side a/c switch. A bad thermostat can cause the fans to come on late.

Why is our 2010 cobalt still overheating after changing the thermostat?it has the 2.2 engine.the temp reaches 210 +degrees.sitting idled and the cooling fan is not turning on.The cooling fan only runs


was the thermostat installed the correct way round . Fans should start spinning at around 75degres c. Check coolant temperature sensor ( not temp. gauge sender unit) for operation. Have a flow test done on the radiator to check for blocked cores.. Have a compression test done to check gasket and for cracks.

Overheating gage when stop & go -2004 chevy tahoe


natural for engine temp to rise in Traffic - Until Themostat opens ) cooling fan sensor kicks on fan . But Antifreeze is not just a Cold weather item . Coolant is Absolutely Necessary for Hot Days . You must be full to recovery bottle setting of cold when checked prior to start up . Coolant for your make / model is Reddish - Pink colour and should have a reading of -25 thats negative 25 degrees the Lower the Better even - 50 .. Why ?? - 50 is 50 %% antifreeze / Coolant Concentrate MIX Gives Hot weather cooling Ability or very cold weather starting / winter HEAT .

I have a 99 jeep grand cherokee 4.7 that is overheating whenin traffic or at a stoplight or drivethru. i have a check engine code p01491 . i have replaced the fan relay.i hhave jumped the fan it works ....


The relay gets power on the gray wire from a 40amp fuse. The relay is grounded and gets a power signal from the PCM on the dark blue and pink wire. The PCM signals the relay if the engine temp reaches 220 degrees or the ac is turned on and it works.
You would need to have a scanner or the means to read engine temp to find out if the computer is signaling the relay on when the coolant temp reaches 220 - 225 degrees.

I own a 2007 chevy uplander v6 95k miles and the cooling fan comes on 20 seconds after car is running. I traced the fuse block to fan#3 by removing fan relay to know which fan is being told to run. it only...


Your vehicle has two fans controlled by three relay's . Both fans run together at two different speeds , low an high ! With the A/C on the fan's will run all the time while stopped at stop sign or idling . Any other time the then only come on when the coolant reaches a set temp. The ETC - engine coolant temp sensor is a input to the PCM - engine computer . When coolant temp reaches 212 degress the PCM energizes the fan 1 relay turning on both fans at low speed . This is very complex ,your best bet ,take it to a qualified repair shop.
