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

I have a 2002 PT. that is overheating, but not all the time. I can take 1 or 2 trips in town and it does not overheat, then it overheats. I have replaced the water pump, Thermostat, low and high fan...


Do you hear the cooling fans coming on ,if you do then you might have a blocked radiator or cylinder head / head gasket problem. If you dont ever hear the fans come on you have an electrical problem ,maybe a fan switch or motor or wiring/fuse issue.

I have a 2002 pt cruiser that was overheating. I flushed the system, replaced the thermostat and heat sensor. Started the car and let it idle for about 30 minutes with no problem. Took it on the road and...


The best way is to do a chemical hydrocarbon dye test at the shop.

This can rule out leaking headgasket.
You did not state the odometer reading....a 2002 should has 70,000+ miles.

====
Check the fan relay(s).

Turn A/C on and see is the fan coming on.

Is the fan fully operational?
====
The last odd ball item is the water pump.

In the past,I saw turbine of the water is totally worn out and looks perfectly OK on the outside and shows no sign of leak.

02PTCRUISER HEATING UP SLOWLY BUT WHEN STOPED HEATS FAST,FANS WORK ,THERMASTAT SEEMS TO WORK WATER TURNS, DOESNT HAVE ANY ANTIFREEZE IS THAT THE PROBLEM?


of course thats the problem. if you had a manual on the pt you will find that this is a pressurized system and just water without antifreeze changes the boiling point. Flush the systen and put the correct amount of antifreeze in, and replace the radiator cap with a 12-18lb cap.

Running hot coolent is fine...


check for a blown head gasket it will sometimes pump air into the heads and make the coolant levels seem fine but in truth they are not and check the water pump for rusted fins make shure the water level sucks down during sharp throtteling of the motor if so the cooling system is fine as far as that goes but where to start

1.) tempature switch located on the motor it tells the ecu when to kick on the cooling fan

2.) fans spin freely without taking force

3.) thermostat it could be stuck closed due to someone at sometime only running water without antifreez and causing the pressure pin to rust and freeze the gate shut

4.) monitor the water levels if they go down suddenly as 1 gallon of water a week or 2 weeks its a bad head gasket you can see this on spark plugs as well

and for most your water pump make shure you get good heat from the heater at low running tempatures and start the car and monitor what the water in the radiator does (while its cold) the water in a car is over 195% and can easily do harm if the car is just warmed up not even close to over heating so you can imagine what it could do at an over heated state



but get the problem fixed or else you can result in blown head gaskets water in the oil piston breakdown do to rust in the piston walls and even worse complete engine failure

2002 pt cruiser overheating was told i need a new raditor and thermostat for 1 grand sounds fishy


Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.
