Default Need help ASAP! Overheating issue

I have a 01 pt cruiser. It started running rough and overheating. I replaced the radiator. But it keeps getting hot. Coolant will be all over the engine after I let it run for about 10 min. I have not been able to drive it in a month. I took the EGR valve off and when I do that the car runs fine but as soon as I put the new one off it started running rough again. The fan works but when you plug it in there is no connection. I replaced the relays. Im just completely stumped at this time. When I go to start the pt I have to keep my foot on the gas or it will not start. Any help would be appreciated.

Welcome to the forum.

Since this is your first post, you probably haven't read all the "overheating" threads that we have, at least you didn't say so. The fan is a known problem and if it's never been replaced before, that probably is your problem. The brushes inside the fan motor tend to burn out so while you changed the radiator, the fan itself should have been replaced. Was the radiator gummed up or not letting the coolant flow freely or did you just decide to change it without testing it to see if that was your problem? Most of us get our parts from RockAuto Parts Catalog for good prices and fast delivery. The fan and shroud (Dorman) runs under $100 and comes with a lifetime warranty.

You took the EGR valve off and the car runs fine, then did you put the old one back on or buy a new valve. They do go bad so replacing it seems like a good idea.

The radiator blew thats why I replaced the radiator. I did put on a new EGR valve and I took the fan out and tested it on another car and it worked fine. Ive been told the it could be a blown head gasket or the Cadillac converter. For some reason getting a straight answer out of anyone has been difficult. As much as I love my car spending hundreds of dollars just isnt what im looking forward to doing.

More specific info would be helpful. Like were the coolant appears to be coming from etc. I would suspect the t stat housing and cap. You also have to get the air out of the system.

agreed.

And when we say get the air out of the system, we dont mean just bleed it. Air can also accumulate INSIDE the engine, where using the bleeder valve will NOT remove the air . you have to "burp" it with the engine running to effectively remove air pockets from inside the motor itself :-) here is how.

How to Burp Your Car's Cooling System | eHow.com

You may have to repeat this process 2-3 times fully in order to remove all the air, check the gaskets and seals around the thermostat and housing, make sure all of your hoses are not cracked or dried out too :-)

Best 2 ways to check the cat are as follows.

Get a laser thermometer and warm the car up nice. Check the temp of the exhaust before and after the converter, if its 10x hotter infront. cat is clogged.

Other way, let her warm up in the dark, crawl under it. If its glowing its gone.

head gasket can be easily checked with a routine compression test at your local garage :-D
