is there any way to test the temp sensor? im having doubts about my temps on the dash because the gauge will only go to the first mark on my gauge even after a long trip so i would like to know if my sensor is bad or if it really is running that cold, what are normal engine temps? is there a way i can check the engine temp without the sensor? and what is an acceptable range ? thanks i really dont want to blow up another engine because of stupidity

 

you can test the resistance of it when it is cold and then re test it after it has been running for a while. there should be difference but i am not sure how much of a difference. you don't need to start a new thread all the time. you could have just add this to your thread about your oil pressure.

 

ok thanks for the advice i think those are all the problems i have right now thanks all

 

Normal proper engine temp is 185-195 degrees. That is what it was designed to run at. There are methods to test the actual temp but if you make sure the correct thermostat is in it then the idiot gauge can let you know if it over heats or fails to heat. The resistance values of the gauge and thermostat change over time so I just know what is normal for my truck and you need to figure out what is normal for yours.

 

ok thanks i just replaced the thermostat yesterday and i must say that was much easier than replacing the thermostat on a saab 900,
