Where is the thermostat located on a 1995 Saturn SW series, 1.9L engine? My temp sometimes runs higher than normal, and have been told that the thermostat might be sticking.

Not if the engine is getting up to normal temp. Could be low on coolant or a problem with the heater core or a blend door under the dash.

Find your low level sensor on the overflow bottle. Sometimes they come embedded and molded into the bottle and you just change the overflow bottle, sensor and all. Should be same as most Caprices.

The hoses that are "cut" are silicone and better quality if properly cut. They withstand more heat, but Molded hoses have advantages too.

What I do not see here is any mention of a Thermostat. Lack of one would explain low temp readings. Also if you saying "Beyond the cold" is below the cold mark, then the water temp sensor(sends info to dash) may not work or the dash gauge is broke. When the car engine runs, it should move higher than cold.

You will need proper operating temperature for all the engine controls to work normally and will get better gas mileage.

depending on what temp your thermostat is,sometimes some engines run warmer,make sure it doesn'r run hot,and keep flushed with new antifreeze every 12,000 miles.

Replace the thermostat which is located inside the lower radiator hose on the block side.

Get the Stant 195*F thermostat. As long as you replaced the engine coolant temp sensor than the t-stat is the next thing to replace. Also as a double check make sure your dial on the inside of the car is properly actuating the arm to move it to heat.

IF ENGINE RUNS AT RIGHT TEMP SOUNDS LIKE YOU MAY HAVE AIR BLOCK, OR BLOCKED HEATER MATRIX, CHECK FIRST CHECK THE HEIGHT OF THE HEATER MATRIX IN THE CAB , IF ITS HIGHER THAN THE FILLER/EXPANSION TANK. THEN COULD BE AN AIR LOCK, LOOK FOR THE HIGHEST PIPE AND SEE IF THERE IS A BLEED VALVE, IF NOT TAKE BOTH PIPES OFF THE MATRIX FEEDS (TWO PIPES GOING FROM ENGINE BAY TO INSIDE OF CAR, AND FLUSH OUT WITH HOSE TO SEE IF IT IS BLOCKED, AND RECONNECT LOWEST PIPE FIRST AND FILL SYSTYM TILL WATER APPEAR FROM TOP AND RECONNECT RUN MOTOR, AND KEEP TOPIN UP, YOU CAN BUY A COOLENT FLUSH SOLUTION TO CLEAN THE SYSTYM OUT

Any cooling system fault in JULY/AUGUST is a big deal. This sensor is 22$ and can be installed in a COLD engine in minutes.Very small cost for accurate gauge so you can monitor gauge and know if real overheating conditions exist.I would probably spring for a new thermostat while Im servicing that sensor and coolant just for good measure. stay cool

could be clogged cats or may even be bad crank sensor.

thermostat is normally one of the higher housings in your cooling system a rounded type of housing dont leave the thermo out

Check your temp guage in the car, if the car is running at normal operating temp then the heater control valve is bad. If the temp is low then it could be a bad thermostat.

Pull the engine coolant temp sensor, I know it sounds funny but do it if your looking at the engine it is located on the right side of the head.. chances are the ceramic tip on the sensor is cracked.. 15 dollar fix or so should take away from the high idle.. let me know how it works
