Default 2002 PT Cruiser 2.2 CRD COOLING ISSUE

i have the above mentioned car and am having an issue( i think) with the cooling on the engine. It seems to me to that the cooling system is not right, the fans seem, im my opinion, to kick in very early and the temperature gauge never really gets above 1/3rd of the way up the gauge usually just a tiny fraction over the 2nd line, and the heaters are not exactly what i would call hot either is this normal behaviour for this car/engine or is there an underlying problem i need to get investigated, any opinions would be greatly appreciated thanks.

Danny,

We here in the U.S. don't have the diesel engine and there might be something different with yours to turn the fan on early. A known problem with the heater not giving off heat is trapped air in the coolant system. The air stops the hot coolant from circulating into the evaporator and giving off heat.

Of course if the fans are cooling off the coolant to a point where the water doesn't reach operating temperature, that in itself would stop you from getting heat.

Doesn't the guage reach normal temperature (half way) when you stopped at idle for a few minutes? It if does, and your still not getting heat inside, then try the trapped air theory.

2nd line from the stop (bottom) if it's the same as ours, seems to be running cooler than normal and your saying it never gets hotter than that.

From my search through the internet your problem could stem from 3 different things. The thermostat, air in the coolant system and/or the heater control valve.

Danny,

All I can do is show you where ours is at and you can go from there. Good luck.

Miss ejd,

Please start a new thread on your problem. We are trying to help an owner with a diesel engine from overseas. If you go back to the main section under Tech and Performance or General Discussions and hit "New Thread" you can ask what you like about your problem.

We will need more information about your PT also. Mileage, maintenance performed, and if you did the work yourself of changing the thermostat and coolant sensor.

It sounds like the stat is stuck open to me, but I would like to see the car.
