When cold, your engine runs from a different computer mode than when warmed up...It seems that when you reach temp, the normal "run" program transitions in (undercomplicated version) Usually when the signal from the temp sending unit does not change (bad sender) the engine will remain running but will run rich. Usually if the sending unit wire is disconnected it will also remain in "cold" mode. I'm thinking that possibly the sender is internally shorting out or the computer isn't working correctly. If you have an engine light on, likely you can retrieve a code that may point you to something in that area. Or, since sender isn't very costly, change it and see if the problem clears up. (I'm not a big fan of just putting in parts without testing, but in this case it may pay off)
Good Luck

How to replace the thermostat on a 2002 chrysler concorde lx 2.7 engine size


The Thermostat is under the connector for the upper radiator hose on the Engine. Trace the upper Radiator hose back to the engine and remove the 2 to 3 bolts holding the engine mounting to the engine. The thermostat is under that. If you don't have the thermostat already you can remove it and replace the cover and drive to the Auto parts store and purchase it then drive back and put the new part in after the engine cools. If you are replacing this because of over heating doing this will tell you if that was truly the problem or if the problem was actually the water pump. Using the vehicle over short distances without the thermostat will not damage your engine in the summer months. It is mainly there for winter months to let the engine warm up before the cooling fluid starts flowing anyway. Heck, I have one vehicle that hasn't had a thermostat in it for 2 years now. Runs great.

Have a 1998 Chrysler Concorde with 134,000 miles. About 2 months ago it started stalling intermitently. Would stall and I could restart immediately. Now it stalls once every trip at a certain engine temp....


your car problem is overheating, some car model like yours is designed to shut-down engine when engine temp. rise so as to avoid frying the engine. your engine overheating problem is attributed by one of these factors:
1. check or refill radiator water if less
2.check radiator cooling fan operation-if damaged pls. change or check the electrical system.
3. damage/ worn water pump-if damage pls. change the water pump.
4. check for any coolant leak somewhere the coolant line-pls. rectify the leak.
5.worn coolant reservoir cap- change if damaged.
6. clogged radiator-if clogged pls. change it.
7. damaged thermostat valve.

Temperature gauge is up and down


Sounds like youve noyiced the first sign of a failing thermostat.Its now taking more heat to open the thermostat or its jamming on the slide when it opens and closes.Good luck with it and pay special attention to your temp gauge until its replaced.

Transmission


Make sure that you check you fluid in accordance with the manufacturer's recommendation. Usually with the engine running and warm and the transmission in neutral.
