Use the 195, this is the correct temp for the most efficient engine operation and fuel mileage.

The heater in a 1996 cadillac fleetwood does not blow hot air when engine is idling, it is just warm, when the weather is very cold, (below 25 degrees.) when it is not this cold it seems to work...


I am guessing you have not changed your thermostat from a summer one to a winter one. If this is the case you need to put a 195 degree thermostat in to replace the 165 degree summer one. Let me know. Thanks.

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.

Cooling fan stays on on my 200 l-series saturn but the car drives fine why would the fan be staying on


1. Check for a code P0128 stored in the Powertrain Control Module (PCM)

2. If there is a P0128, clear the code and see that the coolant fan turns off.

3. Replace the thermostat and check that the coolant temperature stays close to 195 degrees while driving.

No heat 1999 Jeep Cherokee


...You need to make sure you have the correct thermostat! Usually, there are 160, 180, and 195 degree therms for this jeep. 195 degree therm should be used no matter what the season. If you have a lower temp therm., you will not get good heat (or any at all) in cold weather. Also, You should flush and fill your cooling system to get any contaminants and/or debris out. Check the heater core...it may be **** at this point!

Thermostat or heater


If you mean that the temperature gauge stays in blue area, likely the thermostat is stuck in the open position. Yes>>> change the thermostat. Ues one rated at 195 degrees and don't forget to buy a gasket and some glue to install. When re-filling coolant, fill the system as much as you can through the radiator, Start the engine and run 'till it gets very close to operating temp. Monitor cooant level and add as needed while engine is running, cap off. When close to or at operating temp, turn engine off and wait about two minutes. RE-start engine, run with heater full on and continue filling radiator slowly till it is full. Close cap, drive about 1/4 mile, top off recovery bottle and you should be finished. (while filling, sometimes coolant will back up and spill over. this is normal. keep a pan under car to catch whatever you lost so a cat or dog dosen't drink it.)Check system for leaks... especially in very cold weather, hoses will need a small amount of additional tightening after they are hot.
Good luck

make sure antifreeze is full. run engine 10 min. verify engine is around 195 degrees. if not, try replacing thermostat. if it is running at 195, then maybe heater core problem or heater control not functioning properly
