SOURCE: 2002 Pontiac Grand Prix Thermostat

as you face the engine the thermostat bell is on the right (drivers side) Follow the radiatoe hose. Remove the two bolts and raise the bell still attatched to the hose. the thermostat is there with the rubber seal. You can gently pry the thermostat out with a screwdriver or something similar. Put in new thermostat be sure it is the same as the old one, and then replace or change the seal (be sure it is the smae size and thickness as the old one as I got the wrong size from Napa) Then replace the bell, and tighten, but not over tighten. I hope this helps!

Have you shop perform a "leakdown test." You probably have a bad head gasket )or a leak in the gasket).

SOURCE: how much to change a oil pan gasket for 2001 grand prix 3.8 gt

If you want to repair the oil pan I would also check lower engine mount for leaking oil and cracks in anti sway bar near fitting's. This due to engine mount is oil filled. OEM sway bar is made of tubular steel and they crack easy. Replacement sway bar is solid steel. Here's the kicker. When they pull the lower frame to service oil pan. The engine mount and sway bar are attached to that frame. A honest mechanic should only charge for parts ($35 for mount and $100 for sway bar) and maybe a extra hour. My mechanic did all in 5 hours. FYI gasket is only $35 bucks. Good luck

SOURCE: 5.2 1994 Jeep Grand Cherokee overheats at idle

I don't remember ever seeing a Jeep that did not have an electric fan as a supplement to the mechanical one. The electric one should come on when the A/C is engaged. Jeep radiators are far smaller than they should be due to ground clearance issues. The only way to make them work is to enhance air flow through them by using electric fans. (or adding an extra row of cooling cores such as in the special tow package). When the vehicle is moving there is enough air flow created by that to eliminate the need for fans altogether, but you have to stop sometime!
Your a/c compressor adds to engine loading (why it pulls rpm down) When at idle with a/c on, the engine "thinks" it's going up-hill and produces more heat. The heat needs to be scrubbed from the system or it can and will overheat.
Make sure that the clutch fan is engaging. It spins free when cold but should lock up after it gets hot. Add an electric fan to the system...check with several scrapyards and see of any Jeeps like yours have one and take it.(some electric fans are on the drivers side and some are directly in front of the mechanical one) If equipped, there is wiring for it in the car. If necessary you can add one either inside or outside the radiator and operate it by way of a switch and relay or just a switch. (there are aftermarket ones that are "slim line) and are designed to fit between the radiator and the front grille) You could also add an external transmission cooler...in doing that, it will take some of the heat load off the radiator. Also make sure that the new radiator has the same number of core rows as the old one did....some shops mistakenly put ones with less cores in when replacing due to cost. In a system with a marginal design this can become critical. (most radiators come with one two three and even four rows)
Once the problem has been solved, don't forget to put the 195 t stat back in or the engine controls won't work properly.

SOURCE: 2004 GTP Grand Prix overheating in slow traffic

Are the cooling fans coming on during normal operation? If your ac works turn it on and see if it overheats with ac on.If it does not overheat the fans are not operating properly under normal operating conditions.The ac will force the fans on. What you can do to start is just let the car idle in park and see if fans will come on normally. The coolant temp should reach 200-210 before the fans will come on. Make sure the air is off at this time. If we can verify the fans are working or not working properly we can go to the next step. Let me know what you find out.

A head gasket would mean white smoke out the exhaust.
You may have to change the thermostat.
Check water pump flowing fluid thru radiator.

drain the coolant
remove the overflow bottle 2-10mm speed nuts
remove the drive belt
remove the water pump pulley(center of the engine and no groves)
4-8mm bolts
remove water pump bolts 4-10mm 3 of the 10mm bolts are on top and the other is under the pulley flange in the center
4-13mm bolts are on the side(they are long bolts they also go through the front cover)
take a hammer and screw driver and tap the pulley flange to break the pump free
clean the old gasket off
and install the new pump
and reassemble
open the bleeder screw on the thermostat housing
fill the rad
close the bleeder screw
start the vehicle and run to operating temperture

Make sure your cooling fans are coming on when the temp heats up. Are you talking about a leak inside the car or outside? Inside is usaully a drain tube for the A/C stopped up. Outside, look for a water pump or intake gasket.
