As soon as you turn it on after it has been shut off for how long? you could have a bad sensor. if you have a sohc (single overhead cam) engine you have a coolant temp sensor. if you have a dohc (double overhead cam) engine you have a cylinder head temp sensor. either way you will need to start with everything cooled off, drain the coolant, remove and replace the sensor. for the sohc engine you have to remove the ignition coil to get to the sensor, for the dohc you have to remove the alternator. in both engines you are supposed to torque the bolts that hold the sensor in place to 89 in-lbs, tight enough to not have a coolant leak at that point, and not so tight that you stretch the bolts or break them off in the block. if you still have a problem after you replace the sensor then you probably have a bad water pump. hope that helps.

Radiator fans not coming on. replaced thermostat and cooling sensor


Hi Bill, is the engine actually getting hot enough for the fans to come on? if the engine does have overheating problem (but you say the temp gauge reads normal) then i would check the operation of the engine temp switch, there are two, one for the gauge and one for the fans.

Radiator fans not working car is running hot.


Turn vehicle off. Allow to cool. Raise hood.
Try to see if the fans spin freely by hand. If not, replace. If they do spin, proceed to next step.
Next step-
Check coolant level, add if needed. Remember-radiator must be cool before opening cap. Make sure radiator cap is secure and tight if coolant was added.
Start vehicle. Observe coolant gauge as vehicle warms. Fans should come on when temp gauge reads halfway between c and h.
If fans do not come on see if they come on when you turn on ac or heat. If doing this makes them come on, suspect faulty cooling fan sensor switch. If they don't come on replace cooling fan sensor switch and fan relay.

My 1996 Nissan pickup temp gauge does not heat up. Reads cold all the time and the heater does not blow hot just warm. Any suggestions?


Must be cold out! if you never get any heat on gauge check engine open hood and see how hot engine is getting you will know if engine is at operating temp (170-195 degrees). if yes is there a thermostat? if there is one it could be stuck open even then you should still have at least a little heat. change thermostat last resort a little cardboard in front of radiator will get you by in a fix. Exercise caution with cardboard watch gauge don't want to over heat engine...

Temp. gauge reads high some times. but the motor really isnt hot


It sounds like the coolant temperature sensor is beginning to fail. It is highly unlikely that the in-dash gauge is a problem. The coolant temp sensor inputs to the computer affecting everything from radiator fan speed, engine fuel/air calibration and a variety of other parameters.

Be absolutely certain to "burp" every bubble of atmosphere from the coolant system too. Air bubbles have the amazing ability to prevent coolant flow and will cause all sorts of problems, especially if the bubble wants to hang around the temperature sensor location.

Normal operating temperature is going to be around 210 F.

Most Autozone, Advance locations will read engine problem codes at no charge, so drop by one of those locations and let them read the problem code.

My guess will be the coolant temperature sensor. Then have the problem code reset, remove all air from the coolant and let us know how this worked.
