Thread: 04 grand prix gt temp gauge problem

hello, i just bought a 04 grand prix gt and yesterday it was really cold, around -20. my temperature gauge did not move at all in 65km on highway at 120 km/hr and when i arrive in the city, my temperature gauge went up a little.
my heater was running fine. my grand prix is hard to start also when its warm, i sometimes have to gives some gaz to start,i tought it was spark plugs but i have read on others threads and it seem reliated. and i have a check engine. so wath should i do first? thank you


sorry for my writing im french, im from quebec

i just did a reset by disconecting my battery and the check engine left and my temperature went up.

i still have the same problem, my gauge wont move if im driving but if im on idle after a long time it will start to raise really slowly. i really need this problem fix cause its -35 celsius and i dont have much heat. wath can it be , thermostats?

is there a way to test it? or should i just go buy another thermostats?

i just called for the thermostats, they sell it 20$ and they charge me 70$ for the labour. does it really take an hour to change a thermostats, im sure i could do it faster than that at - 35 lol

ya will do , i didnt want to do it cause its -35, ill probably do this this week end, people told me it could also be some air in my coolant system i dont know lol. i think im gonna just buy a thermostat anyway it would be a good maintenance and ill check the coolant system if everything work fine. thank you for your help

this morning at 5am got a bad surprise, car had a really rough idle and stalled.it did that like 5 times. i took my ford edge to go to work, i just called the towing to go to the garage at least i bought this car for very cheap.

problems are solved!!!!! it was the fuel filter and my thermostats. thank you everyone
