Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hi Im David, thanks for visiting the site. there can be a few things that can cause this. 1. check the coolant level, make sure its full 2. there can be air pockets in the cooling system. Has any work been done on the car lately? what does the temp gauge get up to while the car is just sitting there running?
check the coolant level is the first thing to do. then you need to know what the temp of the coolant is getting to sitting at idle. without a temp gauge, you will need to have a scan tool that reads live data to determine if the thermostat is opening at the right times. you can also feel the upper radiator hose and the lower radiator hose. they should both be equally hot.
