02 PT Radiator Fan Stops Working Intermittently - Car Overheats

02 Non-Turbo - Radiator fans is not coming on as it should, which results in the car overheating. This has been a lingering problem over the years. I have replaced the radiator, relays, fuses. Is this a systemic problem with PT's?

I heed the problem fixed before I give this car to my daughter for college.

    I just drove my 2002 PT Cruiser 20 miles after buying it and after overheating the green coolant came out all over the ground. The oil looks clean. The temp. gauge in the car did not show it getting hot. What do I need to do to fix the overheating problem?
    Thank you,

    fan is not worlking and car is overheating! what do i do?

  • htbeaudet May 12, 2009

    I have a 2002 Cruiser that just recently started overheating when sitting idle. I flushed the radiator and replaced the thermostat and added all new coolant. Still, it overheats. I did notice that the fan comes on when the air is turned on but I'm now questioning if the fan isn't working all the time?? Someone suggested wiring it so the fan starts when the car starts and turning off when the engine is shut off but I have no clue where to start. All help is appreciated. Unless you think it could be something else, all suggestions are appreciated as well. Thanks!!

I had the same problem and researched it and found 1000's of other people having the same problem and spending lots of money replacing water pumps, radiators, thermostats, switches, relays,,, etc. What I did was check the cooling fan with 12 volts and found 1 speed doesn't work. I wired the fan so it comes on when the key is turned on and goes off when you turn the key off. The a/c is cooler than it has been in 3-4 years. The temp guage goes to right under half and it doesnt matter if you sit and idle or drive the interstate the temp stays the same and the a/c will run you out of the car. Fixed for less than $5.00.

It could be a fan motor that is failing or maybe just the fan module relay. the relay can be bought at any dealer or auto parts store for anywhere from $20 aftermarket to $90 dealer price. I have seen this many times to think it is another water pump or t-stat. I would suggest the relay. When the relay has gone out then you can still hot wire the fan to working all the time the vehicle is running. With a new relay it will shut off like it is supposed to and run when it is supposed to to prevent overheating. The relay itself may be the problem but it has been known for the whole fan module to go out as well with the relay also. Call your local dealer and ask them to run your VIN # to see if they have a RECALL for this problem before buying anything. I know on a lot of Chrysler products there is a fan recall and the fan relay recall. If your vehicle has these recalls then all it will cost you is your time and gas to get there. Hopefully this helps you.

Assuming the radiator fan works correctly, my guess would be a leaking head gasket.

When your daughter rear ended the other car, she could have caused one hose somewhere to get a kink in it. Please follow especially the pipes underneath to check for a kink. It may be a very small hose but it can cause this problem. It did it to my 1990 VW Golf GTI.

It could also be that there was a metal pipe that bent also and water is not circulating properly.

02 sunfire overheating

make sure you have radiator full of coolant
run the car to operating temperature
check the operation of the cooling fan
feel the upper radiator hose and the lower radiator hose. they both should be hot.
if one is cold then you may have a bad thermostat or restricted flow
if cooling fan does not come on when engine is hot then you have bad cooling fan switch, relay or motor.
good luck

My 1996 Volvo 850 2.4 I5 non-turbo appears to be overheating. I replaced the Thermostat but it still appears to be overheating. How do I troubleshoot to see if it is the radiator or maybe the cooling fans?

first you need to check your cooling fan working you can do so by turning your a/c on if your a/c is working properly/if so turn off a/c and let car sit till overheat and see if fan kicks in.if not possible your fan circuit electrical or sensor related/and also check for air in your system bleed system good check for circulation open radiator cap.

the electric cooling fan for the radiator will not turn on when the engine reaches normal operating temp, its only supposed to come on if the engine temp goes over the normal temp. (around 220 degrees)
it is normal for the fan to come on any time the a/c or defroster is turned on.

I have a Datsun/Nissan 280ZX non-turbo (Not a 210)

Have the thermostat tested first. You can do that by observing if the fan turns on when the fan exceeds your normal running temperature. You may want to check the radiator cap it may be worn out that some steam may come out through it causing temperature to increase in the process.
