Question about 1997 Pontiac Grand Am

1 Answer

Cooling system leakage/temperature fluctuation

I own a 1997 pontiac grand am 6cyl and the temp gauge will go from 100 degrees to 240 in a matter of minutes then down to 110 up to 240 and so on. my mechanic told me after i had the radiator repaired and all hoses replaced that there was this seal i needed to get and it would cost 600 dollars to fix it. i just want the name of that part i need and i can get it repaired for a much more reasonable price. thank you for your help.

Hi, the fan in the cooling sistem plays a very important role ,if the fan dont work properly that kind of temperature variations may happens,this can be coused by a bad temperature suitch, a bad relay or defective fan ,,another posibility is a bad thermostate ,even if is new it can be defective, water pump should also be checked......(never heard of any seals.) GOOD LUCK..

2004 Grand Cherokee Temp Gauge fluctuates and Chk Eng ite comes on


I would check that the circulating water pump connected to the radiator is working properly. Why else is the temperature fluctuating? Get a computer read on that engine- a free diagnosis from the service department at the dealer should take about two minutes and tell you everything. Only the dealer can pull up the total diagnosis, because certain codes can only be recovered by the brand equipment. NOT Autozone

Temp gauge


If the gauge were faulty, it would not be accurate. And no it would not affect the engine cooling system.
It sounds like your radiator fan is not working, or the cooling system is low on coolant. The fan should come on when the engine temp reaches 220 degrees.

Engine coolant Temperature gauge fluctuates


Watch the temp gauge when the electric radiator fans come on. The temp sensor that controls when the fan comes on may be faulty.

Where is the fan temperature sensor located


actually, the ECM directing the sensor to actuate the switches. the engine thermostat is the actuator of the fans in the cooling system. and its located in the oulet port of the engine where the upper radiator hose is connected. (and or at the lower rad hose, some design on VWs).

Coolant temp rise to around 210 degrees when idling or in stop & go traffic bur drops back to around 196 when cruising. Is this normal?


completely normal those readings are perfect this car comes with a 195 degree thermostat,210 is fine for stop a go traffic remember a cooling system with the proper amount of coolant in it and under pressure will not overheat till about 240 degrees your in great shape no conerns!!!!!...

Radiator fans don't keeping running to keep the temp constant of the coolant


the fan only runs when the coolant temp reaches 225-230 degrees F, the temp will not remain constant, it will climb towards hot and then the fan will engage and bring it down, this is normal operation

2000 Pontiac Grand AM little heat being produced.


1st thing to do is change the thermostat. It is either missing, or stuck open (you provide good info). This is why the car is not running at operating temp and why you have little heat. The no blower for settings 1-4 probably means a bad switch.

1999 pontiac grand prix gt dual climate control not working prope


The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.
