Overheating

[snowwhitetiger]

I have a 2004 PT Cruiser with an overheating problem. I replaced the Catalytic Converter‎, Thermostat, Pressure cap (16psi), and have done two radiator flush myself. Now when we replaced the Catalytic Converter‎ it run good for two and a half weeks the through a code. It was running cold, that's when we replaced the thermostat. It run hot so we did a flush and replaced the thermostat again with a fail-safe, Pressure cap (16psi). Now the weird thing is, we can drive it for more then half a day, and then stop at the store go in spend a hour come out head home and it run hot. I know its running hot because its pushing water and coolant back into the over flow tank. I do believe the water pump is working good because I can take the radiator cap off and put my hand over the hole and it will suck my hand down to it not much but if I rev the motor the presser is a lot more.

Have you checked the radiator fan? A known problem with the PT.

when I made it home I left it running and checked and it was running

Maybe radiator is stopped up?

I have considered that, but if it was...Wouldn't it have keep water from coming out when we did the flash?

Not that you do but could be only partially blocked.

I have looked and have found some for as little as $58 and as much as $130. Is there any thing that needs to be known before going cheap or expensive?

May not be your problem. If it is and your going ebay, free shipping is good and seller's rating is very important.
