Pt cruiser 2008 overheat i change the raditor and the fans , thermostat and still overheat lot of money and still


Has the system been flushed? Correct temperature thermostat installed? Are you getting flow through the radiator? Rad cap sealing properly and is it the correct one? Are the fans actually coming on? Is the temp sensor working properly? Rad properly filled or still have air trapped inside? Water level correct? Water pump working or seized, leaking?

Cooling fans don't work


Did you recently change the coolant or have it changed? The system needs to be 'bled' or 'burped' of any air in the system. I did this for a friend once to fix an overheating issue.

There is likely a relay for the fans or the coolant temperature sensor that is bad. You'll need to get a Haynes repair manual (library) or look online for a service manual for your car...also, search the online dodge/plymouth/chrysler forums.

My guess is the relay that is bad IS causing a fault to ground that is draining the battery, too.

You could just remove the Negative battery terminal every night 'til you get the fans figured out.

Since it's overheating while idling it could be:
-water pump
-thermostat
-radiator plugged
-low coolant

Unfortunately, these engines have a history of blowing the head gaskets, too.

You could have a worn out water pump
The impellers will wear down over time
The fan Belt may not have adequate tension
The radiator may need flushed

Good Luck, I hope this gives you some things to consider

Sounds to me like the impeller in the water pump is corroded bad enough that you now have no volume of water flow.If a pressure test on the cooling system shows no leaks and the rad fan does in fact run then this is the most likely solution,if the fan does not run you may need a temperature switch or a fan motor.

My 2004 TrailBlazer overheats in running only I changed acdelco water pump , thermostat and coolant water and still overheat


check your fan clutch, very typical problem on these 4.2L engines. These fan clutches are electronically controlled. Another issue may be clogged radiator.

Overheating


If you have seen the signs of leakage around the water pump thn its worth replacing it being that far already.
Its better too, to flush the radiator.
Usually if the seal blows thts the end of the pump even if it looks ok!

Running hot


Check the Tension on the Belt. If it is not tight enough or you need a New Tensioner for the Belt, It will run hot. It is not letting the Water Pump Cool the Motor fast enough. You might also Check the Radiator. If the Radiator is Even a Little Clogged, It will overheat. Also, Check the Fan clutch, If it is not working Properly, You will overheat. Let me know what you find!
