First of all are you sure you have a sl1 and not a LS1?The SL1 model never traps air in the cooling system.But the LS1 trap air all the time plus the LS models i have changed tons of heater cores and the SL model barely have ever changed any.

Ok just making sure after my many years of working on saturns i have found a lot of customers are unsure of the model they have.I just dont want to waste time giving info on the wrong model.So does your ac work?If so turn it on does your radiator fan come on with the ac?Also how hot does the temp get?The radiator fan comes on just after the temp gauge goes past the half way mark on the gauge.Also the coolant is full?

So the radiator fan under hood that attaches to the radiator comes on with the ac?Iam not talking about the inside blower fan that blows air into the car.

It should always come on with the ac if it doesnt it will cause the ac compressor to turn on and off.Try it now start the car up and turn the ac on make sure the ac compressor kicks on is the radiator fan on?It really sounds like your radiator fan has failed from your symptoms with the ac and the overheating unless your moving.
