SOURCE: replace thermostat on 2003 grand prix gtp with

The thermostat housing is located in the upper radiator hose. You will see a metal elbow secured by two bolts into what I remember is the upper intake manifold...don't quote me on that but you will see it regardless of whatever I call it. Anyways, GM decided it was a good idea to put stainless steel bolts in there but that makes it easy to strip the threads in the bolt hole so I think it's best when you put your wrench on the bolt to just tap on the handle till you vibrate it loose, then turn it.
When you pull off the housing you'll lose a little coolant and it will create an air pocket which we'll address. It's a 50/50 chance that the thermostat housing gasket will either stick to the housing or the engine...it may be torn, cracked or flaking in either case clean both contact surfaces before you replace the gasket. I recommend an oil impregnated poly material gasket.
Note the position of the thermostat in the hole and place the new one in as such.
I recommend a 180 degree thermostat...stock is 195 but the GTP runs better with the 180.
Put on gasket and reinstall the hose/housing assembly, alternate from one bolt to the other so the housing mates flat and cannot cause a leak.
Next, fill the coolant overflow bottle to the "HOT" mark. If the bottle is dirty and hard to see just put a light on top of the bottle...GM didn't mark it very well so if it's not squeaky clean you can hardly see a damn thing.
*IMPORTANT** if your car still has Dexcool in it, DUMP IT. It will eventually destroy the motor.
If not...continue on. Start the car. Go back to the thermostat housing and place a rag on top of, and twist the peacock valve on top of it to let the air out until it starts to get coolant on the rag. Done.

SOURCE: grand prix torque converter locks up too soon

Either the speed sensor, TCC solenoid , ECU or a stuck check ball in a lockup plate. I recommend taking this to a transmission shop this could get fustrating.

Why does my 2003 pontiac grand prix maintain speed on flat surface when cruise is not turned on?


Sounds dangerous and hard on breaks. I\'d catty with the throstle linkage under the hood. It should twist open with a bit of pressure, than snap shut when you let go. Yours won\'t. The return spring is worn, stretched out, or most likely gone missing or fell out. Find it and hook it up. Or any spring with the power to pull it back to a closed position. Must be hard to restart the car after it\'s warmed up too.

Irecently had my transmission fixed by AAMCO. Ever since the repair my cruise control works intermittantly. 1998 Dodge Grand Caravan.


Some cruise controls are vacuum controlled check the vacuum lines make sure they are hooked up and are not leaking air or sucking in outside air. Another cause could be the cruise control switch around the brake pedal. There should be two there is one for the brake lights and the other is for disengaging the cruise control try bending the bracket downward a bit and maybe spraying some WD40 on switch in case it might be sticking due to wear so the switch operates freely. Happy motoring!!!

Cruise Control - 2000 Mercury Grand Marquis LS - not working


Your manual should tell you that. Also check your brake light switch by the brake pedal. It also disengages the cruise. If it is bad the cruise will not work but the brake lights may still work.
