Well, I decided against the Blue Devil and was gifted the cash to replace the head gasket and the fan relay assembly. so that means the entire cooling system has been changed within 4 months. It better not give me any problems!:)
I want to keep the car for at least 2 more years! Good luck to all.

I purchased a 2004 pt cruiser from one of the most disshonest lowlifes i have ever met in my life so far. Said they changed thermostat and radiator cap and told me the machanic said it was fine. Ha Ha it didnt even make the trip home.It was over heating bad and the fan was running . I think the coolant was burning out the tal pipe. I called the person i bought it from on Craigs list and told them what happened and they said theres no lemon law in Iowa and hung up on me. Lovely just my luck. I got it pretty hot about three times limping it along to get home. Probly time for a different engine.

I was also have the same issues as everyone above. "Car slowly started having overheatig problems while running and gas was bubbling into the overflow bottle" The problem was due to the radiator being clog 50% the tempurature of the radiator was was over 100 degrees cooler at the bottom with small hairline fractures in the corners. 5 of them to be exact. I has the radiator replaced and the problem is now fixed. WARNING! if the pressure test is good YOU DO NOT NEED A HEAD GASKET!! Dont let anyone talk you into it your car will never be the same.
Hope this helps.
NOT ALWAYS. Firestone told me at least 4 times that my 2002 PT Cruiser pressure and chemical tested good. After $2249 and 9 trips, it was the head gasket. Quick check, with radiator cap off, let engine warm up. When thermastat opens water should flow past open thermastat. If it blows out (stand back), there is pressurized air in your cooling system. Other signs,coolant coming out the drain tube on the firewall across from the overflow bottle and loss of coolant, Car was fine in cool weather with not A/C.

I also have a 2001 PT Cruiser and it overheats I live in town so every time I go into town it overheats on the highway it doesn't overheat. I was reading all the comments and this guy was talking about the connector for the radiator fan, I believe that is the problem can someone please tell me how to check it. Thanks

A sum of my older post buried in this thread-(and some of it is repeated)

The fastest way to tell if you fan is not working is to open you hood, turn your PT on (engine running), and turn on your a/c.

If the fan is not running -Bingo! there's your problem.
Most likely your radiator fan.
a) Worn out rad. fan motor/ clip holding motor to fan worn or loose (my g/f's PT problem,$100 part 3 hours to fix in driveway)
b) Bad Connections
c) Bad Relays

Next, could also be:
a) Bad Thermostat
b) Radiator Fluid not bled when refilling radiator
c) Wrong type of Radiator Fluid

Results from driving overheated because of above problem-
White smoke from under the hood = crack or expanded heads ($1000+ repair job)


Your fan kicks on when the a/c is on or the temp reaches a certain point. You fan will kick off at 35 mph - at that speed the airflow from outside to your radiator is enough to cool your radiator coils.

To check your fan - turn your car on and turn the a/c on. The fan should be running. If not, see #1 below.

Most likely causes:
1. Fan motor is burned up - happens a lot. New fan motor $99 and a few hours of work.
2. Relay(s) not working - you will be lucky if this is your problem ($10 fix), but probably not.

Good luck and DON'T(!!!!) drive with the temperature in the red zone!!!! <or even close> If you see white smoke from under the hood then you've screwed up and it will cost you $1000 -$2000 to get you heads fixed.
I got the fan fixed but still overheated and spit out fluid through the overflow tube by the firewall. This was the first car that I had to bleed the radiator fluid. From my mechanic buddy, he said that there are small passages in the engine where air bubbles can block the flow. There's a little valve right below the radiator cap on the right hand side that you have to loosen while filling up the radiator with fluid. It's best to have a 3/4" or 1" hose placed on it ran to a pan to catch the run off radiator fluid from being bled.
Bleed the radiator-
Right below the radiator cap (1" or 2" inches) there is a 10mm nozzle to the right. Just unscrew it when you fill your radiator up. It is recommend that you get a hose to drain the overflow in to a container (you can reuse it again). I got a 3/4" clear hose from ace hardware,$.79 per ft, to drain it into a pan. You want to keep pouring radiator fluid in until the fluid that is being bled is a solid stream - no bubbles. BTW, my fiancee's car already had the green stuff in it when we bought it, so that's what I continued to use. The HOAT is good for 5 years, where as the regular green stuff is only good for a few years.

See my long post above-

Check the radiator fan first

Make sure you or whomever bleeds the radiator while putting coolant in. There is a bleed valve on the right hand side of the radiator fluid fill opening just below the radiator cap.

If you run your car once it hits the red area and it dies or you have a bunch of white smoke - it's your heads and maybe more you messed up.$$$$

Alright my cruiser has become a nightmare. Started overheating so I replaced thermostat and pressure cap. Started overheating again so I replaced my water pump and coolant temperature sensor underneath thermostat housing. Burped the radiator and now only overheats when idle and reservoir sounds like it's boiling. I don't think it's my head or head gasket cause there is no indication of cracked head or head gasket. What are,the few reasons left why this thing is overheating?

My 01 PT Cruiser is still overheating after changing water pump timing belt, thermostat and radiator cap.From reading other post it sounds like their could be a cracked head. If so is the something the mechanic should have noticed while changing the timing and waterpump?
