check if the fan is actually turning on when it heats up. It wasn't in mine and all i had to do was wire the fan to the battery with a fuse and turn it on manually... now it doesn't overheat... there is probably a sensor somewhere that may be going out so check on that maybe... also what my mechanic friends told me is that the oil gets burned through the piston rings out the exhaust and that's why you have to keep adding oil. (this may be why the oil pressure is low) so just add more oil, look into the sensor for the fan and maybe the piston rings. that gets spendy so I'm not gonna do that one

Dont forget to check your radiator fluid. You may have a slow leak somewhere. Its important to check your hoses every once in a while for excess wear and tear. You can do this simply by giving them a squeeze (especially where the hoses bend and are secured) If you see lots of cracking, it wouldn't hurt to change them.

Also run your car in your driveway for a while with some plain cardboard (no print) underneath your engine and radiator. After about 20 minutes, turn off your car. After another 20 minutes take a look at that large piece of cardboard, and note the various colors of fluid you may have.

My Saturn had the overheating problem when stopped. After further investigation, it turned out that the electric cooling fan never turned on. The only way I was able to get it to stop overheating while stopped was to turn on the air conditioning, which forced a fan to come on to cool the AC condenser.

I found the root cause of the problem was the engine temperature sensor. The temperature gauge was accurate which threw me off until I found that there are two temperature sensors- one for the gauge, and one to feed information to the computer. After replacing the engine coolant temperature sensor, the problem was solved.

If the freon in my ac system becomes to low, my cooling fan will not come on and my temperature gauge rises. I recharged the ac system and the coolant systems stays in check. I guess the fan relay is joined to the coolant system pressure switches.????

Is the motor in this 1993 Saturn slY going to overheat by using a radiator out of a Chevy Celebrity?

If the Chevy Celebrity radiator is smaller that the Saturn radiator it might well overheat from not enough cooling capacity. If the Chevy Celebrity radiator is the same size or larger than the Saturn radiator I would think it would not over heat.

What would cause a 1997 Saturn SC1 to overheat when sitting in traffic and not overheat if moving on open road?

Low coolant level, or the cooling fan(s) are not energizing due to a bad fan motor, sensor, or relay- maybe even a broken wire. Engine coolant temperature sensor will cause that everytime... more likely than anything else because it only does it when stuck in traffic or stop sign to stop sign and not on open road.


What is Saturn's atmospheric pressure compared to earth's?

Saturn is a gas giant, meaning there is no solid surface to compare to the surface of the Earth. Saturn will have a different pressure depending on how far from the center of the planet you measure, just as the earth does the higher you fly on earth the lower the pressure until you get to space. At the center of Saturn the pressure is 50 million bars.

How long does Saturn take to complete one rotation?

Saturn is the sixth planet form the Sun and one of the Gas Giants. It takes 10 hours and 39 minutes for Saturn to complete one rotation on its axis.


How long does it take to revolve around the sun for Saturn?

It takes Saturn equivelent to 29 years to complete a full turn around the sun and it takes Saturn 10.5 hours to complete a turn on its axis. (Therefore a year on Saturn is equivelent to 29 years on Earth and a day on Saturn is 10.5 hours)
