coolant problem

[asite57]

my car never seems to get warm up like ever. it runs at maybe 165-180 degrees and my heat doesnt work, what does this sound like to you guys? its a 1999 GP GTP

sounds like its time for a coolant flush, heater core flush and new thermostat.

That should be plenty warm enough to give you heat I'd say your thermo is prob stuck open though

 

[asite57]

if the thermostat was stuck open wouldnt it throw a code?

 

[dsmuts]

I'm not sure i've had cars with the thermostat out and it still didn't throw a code.

 

[asite57]

besides the loss of heat is there any downside to the thermostat stuck open?

 

[dsmuts]

a little bit worse gas mileage but not much.

yeah ive noticed that im getting worse gas millage lately, i figured itd be good for the car though it runs cooler
