The 195 is factory, and is where you will get the best mileage/wear for your motor. The colder ones may allow deposits to form in the engine, and may cause other problems. If you want it to run cooler, I would go no lower than the 180. You may be able to get a kit to make the fan a direct drive. This will make the fan spin at engine RPMs, but will sacrifice a little power and be alittle noisier. Check/replace your radiator if it is still overheating while driving down the road, or with the A/C on.

I don't understand why my 97 Taurus antifreeze Reservoir is running at 200 degrees or better with a 195 degree thermostat.


That is normal, just because the thermostat is 195 that has nothing to do with it reaching a higher operating temperature. 195 is the minimum before the stat closes to heat the engine up.

Will not heat up put a new thermostat in it is a 195 is there one higher to put in I drove 70 miles and the onlyhthing I got was warm airiI it is a 1994 jeep grand Cherokee


Well the recommended temp is 195 degrees which is the hottest you can get. Anything over 160 degrees will give you heat inside the truck.
You would need to know if the radiator is full of coolant, the heater hoses are getting hot, and the blend doors under the dash are working.

Well i still have the same problem! after i took your advise i took 1998 grandprix to new machanic/ told him what the car was doing getting hot and only cools when( ac) is on he said it was thermostat


I would vote for the cooling fan theory. The engine thermostat is supposed to open up at 195 degrees and allow the coolant to flow thru the radiator. The cooling fans come on at 220 degrees and when the ac is on.
A mechanic would use a scanner to watch the engine temp and see if the thermostat is opening at 195 and the fans are coming on at 220.

WHAT IS THE NORMAL OPERATING TEMP FOR S-10 4 CYLINDER S-10


All vehicles sold in the USA in the past 30 yrs use a 195 degree thermostat. It opens at that temp. Electric cooling fans come on around 220 degrees to prevent the coolant from boiling.

Underheat


Similar concern for the 3.8 V-6...or the 4.6 V-8...the least costly problem is usually a worn out..(stuck open) thermostat. I assume no water leaks? Most costly can be the heater core, due to extensive labor time...Be sure to use OE rated thermostat that opens at 195 degrees...for performance not heat, a 160 degree thermostat is available...but not good for heat build up...not a big job on your Mustang...Hope this helps.

You might try replacing the thermostat. Hows the heater work? That will give you a clue. A stuck or defective thermostat will cause poor fuel mileage and poor heater performance. This vehicle needs a
192-195 degree thermostat to operate correctly.

What the normal temperature operating range indicated on the temp gauge?


195 degrees is the typical high end on the thermostat (when the thermostat opens), so the temp gauge should read a max of 195 degrees, give or take a few degrees. Some people replace their thermostat with a lower temp one, such as a 180 degree one. Then the gauge will read lower (approx 180 degree max). So the range is typically from cold at start to just under 200 degrees.
