Default '02 Cruiser Overheating- Please Help

Hi All, first time poster here.

I have a '02 PT Cruiser Non Turbo Base model that is overheating (actually temp gauge is drifting up about an 1/8th inch from midline but I know the problem is only going to get worse) Here are the facts:

1. Car has about 100,000 miles
2. I replaced radiator, water pump and thermostat at about 90,000 mark
3. My Fan is not coming on when car starts or when it warms up after idling.
4. I suspect my fan used to work at driving speeds because AC would be warm and then cool when the car was moving.

I "THINK" the problem is my fan went from working some of the time to dying all together because of the fact that radiator, thermostat, and water pump are relatively new.

Anyone else have a similar problem? I am having my fan replaced and will probably flush and refill coolant. Again, any help would be appreciated.

Thanks

You think a new fan assembly and coolant flush will do it or could it be something else? Thanks!

These cars have a notoriety for the fan motors being weak. The fan motor has a hi and a low speed, the low speed is foe the A/C and the hi speed is for the radiator air draw. Chances are the hi side is out and not running.
Replace the motor and that should cure that.

Have you also replaced the radiator, water pump and thermostat? If so, there's the high and low speed relays, the fan fuse and the engine coolant temperature sensor.

You could have air trapped in the coolant system or a leaking head gasket.

i have replaced the fan, radiator, thermostat, coolant temperature sensor, and water pump. i don't think that the head gasket is leaking. there aren't any signs of it. i have not checked the relays or bled the coolant system, but the fuse is fine.
