engine and drivetrain Temperature Guage

[PeterCS]

My temp guage on my dash only moves marginally from the blue - makes me worried that my guage or sender is faulty. does not seem like an accurate reading to me.

Where is the sender on the engine?

many thanks,

seems like a quick look with an infrared thermometer would help answer the Q. they're about $20.

Mine used to do the same. Turned out the temp sensor (just above the water pump) was bad and so was the thermo switch between the hoses. Engine was actually running very hot was was reading cool.

Mine is doing the same thing. I just replaced the thermometer and hoses and there was no change. Looks like I need to replace the temperature sender.

Beg or borrow an Infrared temperature gun and aim at the water outlet where the sender is to see what is going on.

It's here:

Cheap and easy to change.

As everyone said for for the sender first they are cheap, I did that on mine and it solved the problem until something went wrong with the grounds and now it's going up into the mega overheat range when the car was just started....sigh

While you are in there...

Grounds.

Check, clean, tighten the ground cables from the battery to the body, from the alternator to the body, and from the engine to the body. This makes up the other half of the circuit for the sensor.

If you pulled the instrument cluster, grounds again. I usually add a star washer under the nuts that hold the temp & fuel guages to the circuit board. Some people also add an additional ground wire to these points using some small ring connectors.

Great thread. Mine too is registering nice and kool.

I wil try the sender first
