Question about 1997 Pontiac Grand Am

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).

2004 Pontiac Grand Prix Temp Gauge not working and car not running properly.

I would check the coolant temp. sensor it should be in the head and have one wire on it. The manufacturers program the computers to change the air fuel mixture, and idle higher when the engine is cold. If the engine is at normal temp and the computer thinks its not it could be idling it up to bring it to proper operating temp.

Cadillac running at 228 degrees to 240 in traffic. Will putting a cold thermostat correct this problem?

It could most certainly be a bad or stuck thermostat, but on a 1997 model, your water pump may be gone (or not circulating enough coolant).
This is why its only heating up while in traffic - there is no airflow cooling the fins of your radiator from moving at speed.
I would check this out - WHILE ENGINE IS COLD - Start the engine and then remove the radiator cap - you should see coolant circulating from the movement of the water pump. Let it run 5-10 minutes to see if the thermostat will open - if it does open, your temp gauge should come down from the opening of the thermostat

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!!!!!...
