98 Saturn Sl2 overheat

While I know electronic gadgets well I'm not nearly as good with cars, aside from basic brake and oil changes.

98 Saturn SL2 160k mi. Overheated on the highway, steam and all, pulled off and sure enough coolant had leaked/steamed out. Let it rest and refilled coolant and was able to make it home with the heater on and the temp gauge reading normal. Coolant light blinked all the way. I checked the coolant when I arrived home and it was low and not pressurized. Just looking for some ideas here/ estimate on prices.

    I'm not sure if it's the themostat i'm haveing trouble with or the waterpump.

    Where does the themostat sit in reguards to both hoses.

    One top hose swings to the right side, the other to the front of the engine.

    Is the themostat under the alternator?

If it overheated without being low on coolant the first time you may have a themostat sticking. But I would start with a check of all the hoses for cracks or loose clamps. Also check leakage at the front of the motor from the water pump. It's hidden behind the a/c compressor but you should see splash marks on the hood if it's leaking there. For good info on how to fix it yourself try There are a lot of good tech tip articles for the S series cars. I lost a water pump pulley at about 90,000 overheated five times getting home. The car now has 230,000 on it and still going strong.

Cant find temp sensor on 1992 saturn sl2 need to change

On the SL2 (DOHC), there are two coolant temperature sensors located on the left-hand side of the cylinder head, near the upper coolant hose. On the SL2, the upper sensor with ONE WIRE controls the temperature gauge in the dash. The lower sensor with TWO wires provides input to the computer. They are not interchangeable. Here is a tip you will need a 14mm deep socket or box wrench. The new sensor may require a 13mm socket or wrench, depending on the manufacturer. Good luck and hope this helps. Keep me posted.

98 saturn SL2, P0172 and misfire dtc's, jerks when accelerating after warmed up. Coolant looked a little frothy but doesn't seem to need coolant added(not consuming coolant)Oil looks good. Problem started...

Possible blown head gasket. Big problem . Have that checked immediately by a engine coolant pressure leak-down test. You can lose your engine and pronto! Small amount of coolant possible passing into crankcase or/and the cylinders.

'98 SL2 Saturn Traction Control

Traction control helps limit tire slip in acceleration on slippery surfaces. In the past you had to feather the gas pedal to prevent the drive wheels from spinning wildly on slippery pavement. Many of today's vehicles employ electronic controls to limit power delivery for the driver, eliminating wheel slip and helping the driver accelerate under control. Don't turn it off.
