Re: Pt crusier 2001 overheating

Ok you say it's overheating. There is a bleeder right below the radiator cap just to the right just below the thermostat. Once it is a steady stream. Your done. To start things off right here's how I do it. Pull the lower rad hose to remove all I can. Put it back on and make sure the clamp is as far as you can on the hose. OK. Pull the housing that holds the rad cap off. USE only g05 synthetic coolant. It's a must for the ceramic bearing in the water pump. G05 is zerdex. Might be misspelled sorry if it is but for sure g05. It's not green or gold. It's orange. OK that said. Fill that as much as you can. Remember 50 50 that car takes 1.85 gallons. So thst said. 1 full gallon of g05 coolant. You can buy at most parts stores. Put the rad cap housing back in. Tip use a little rtv to hold the thermostat in place so it doesn't leak. Now add water make sure the whole gallon of coolant is used. Fill it up. Have a 10 mm ready with cap on if it's maxed full once u have filled the system when it's started. Once it is throw the cap on now use a 10 mm with a 3 inch extension so u can access it. Now once it's a steady stream don't sit on it all day. Now ur bled. Now. When the temp goes up soon as the thermostat opens the fans should kick on. If it doesn't. I would invest the money on a fan. Dorman makes one with the relays on it. OK we done with that stage. Now stage 2. Pull the plugs out one at a time. Disconnect the coil pack so it doesn't start. Do a compression test. If they are all around 90 psi or clise to each cylinder. Do what's called a bleed off. Leave it on don't remove for a few minutes. If it stays up at let's say a 3 second crank your ok on the head odds are. If it drops you either have a blown head gasket or a cracked head. The motor can take some overheating. That said. You now have the info how to so be careful and don't do anything when it's hot. Nothing when hot. Hope it helps. I do not take responsibility for your repair. If the cooling fans never turn on. Dorman. Replace if it stabilizes in temp to a point at idle.
