Question about 2001 Chrysler PT Cruiser

1 Answer

Our 2001 PT temperature gague has been fluctuating from cold to very hot. It goes down when the heat is put to full inside. Water pump was replaced in 2007. Radiator has also been replaced. Coolant was at the correct level. Could this be the thermostate?

The t-stat could be stuck or possibly an air lock

How come i dont get no heat?


The heater core may be plugged with rust. Good way to test it is with the engine warmed up put the controls in heat mode and then go under the hood and locate both water hoses going t the heater core. Hold on to both hoses to see if the temperature of both hoses are the same. If not, no water is getting into the core. . If the temp is the same, then control vacuum is not working. There is a check valve in the line to the control head that prevents vacuum fluctuations from moving the blend door when accelerating. Check it.

2000 Gallant. Installed new radiator, thermostat, and water pump. Why does temp gauge read hot when it's not?


Disconnect the temperature sending unit wire connector for the gague ( not the one for the computer ) with the key on. The temp hand should stay on cold mark. Next, ground the wire and the temp hand should go to full hot indicating the gague and wiring to it are ok. If ok suspect a faulty temp sending sensor if the cooling system is full and properly bled

Audi A6 2001 quattro 2.8 mysterious over heating


Yes, replace the thermostat. Then you need to 'burp the coolant system'. Your car has all the hallmarks of air in the system, especially a heater that is cold. This is because there is no water in the heater matrix. This is why it overheats. The system must be full and with no air to circulate correctly through the radiator.

Burping involves the following steps.

Remove the lid to the reservoir, remove the radiator cap, fill the radiator to the top, turn heating on full blast, start engine and get to operating temperature, keep topping up. Squeezing the radiator hoses helps. The level will rise and then drop when the thermostat opens. Top up when bubbles stop and the level becomes constant. Put radiator cap on, top up the reservoir and put the cap on that.

Is the coolant level full? Sounds like air pockets, as a temperature sensor can't read air temperature. If it looks good, you might have a circulation problem, due to plugged radiator, or heater core, or possibly a worn out water pump. You can also "feel" around the thermostat to see if it's opening properly.
