1998 Saturn SC1 transmission

Clogged radiator, worn out water pump fins, oil pump failing, head gasket blown and leaking into the cylinders, thermostat stuck closed.

sc1 means saturn coupe with a single overhead cam engine sl1 means saturn sedan with a single overhead cam engine same engine and same parts for both these cars

that is because the reason the vehicle is idling so high is because there is a vaccum leak somewhere and it is sucking in cold air

car over heats at idle when i turn on ac it cools down. checked relay fine,fuse is fine.help!

sounds like either you have 2 of the wires crossed.........one is loose....probably #1 or your #1 plug needs regapped or is not tight and losing seal....all will cause a misfire and set the check engine light

first get it scanned for codes 2nd look at the air filter, and the mass air flow unit sitting on top for leaves or dirt , then check the air intake bellows that runs to the intake check it for cracks? also look and listen for vacum leaks around the engine possible cracked hose causing ecm to get false signals from airflow meter? good luck

You either have a bad engine coolant temp sensor & connector.Located under upper radiator hose at cylinder head Yellow & black wire.Original sensor is ceramic & replacement will be brass from saturn.Also you may check for vacuum leaks at PCV hose & valve.Hope this helps

What actually is wrong with the car? What is it doing?

I had this problem. Its a sensor. Unfortunately I don't remember the name of the sensor. When it gets a tiny litle crack in it, this is what happens. If you take it in to autozone, they will do a free sensor scan for you. You can replace it yourself. Its really no big deal. If you get the scan done you can contact me and I will give you further info.

u will need to pull the trans and replace the torque converter front seal.
