fredrogers Posted November 20, 2005 Share Posted November 20, 2005 I just installed a new mechanical water temperature gauge in my 87 gl wagon. What is the normal operating temperature for my car? Thanks! -=fred=- Quote Link to comment Share on other sites More sharing options...
ShawnW Posted November 20, 2005 Share Posted November 20, 2005 Its based on what your thermostat temp is if you are measuring the block temp. A reading of 195, 192, 180, and 175 would be common. Quote Link to comment Share on other sites More sharing options...

Cougar Posted November 20, 2005 Share Posted November 20, 2005 I would guess around 208 deg. F. Quote Link to comment Share on other sites More sharing options...
archemitis Posted November 20, 2005 Share Posted November 20, 2005 212 degrees is where water boils right? but our coolant systems are pressurized so that brings the boilng point up alot. id want to see it within 10 degrees of your thermostat, depending on where your sensor is Quote Link to comment Share on other sites More sharing options...
fredrogers Posted November 20, 2005 Author Share Posted November 20, 2005 Thanks for the good info. I just changed out my water pump, t-stat, and radiator, so I wanted to know if I still had air in my cooling system. -=fred=- Quote Link to comment Share on other sites More sharing options...
MilesFox Posted November 21, 2005 Share Posted November 21, 2005 if you have enough air in the system or the coolant is so low, wayer wont pass over the sensor. beware of a COLD reading when you know the car is warmed up. same when the heat isnt hot if the coolant ois too low my sedan leaked at the water pump and i would leave the heat on. once the heat started to get cold it was time to pull over and add another gallon of water Quote Link to comment Share on other sites More sharing options...
fredrogers Posted November 21, 2005 Author Share Posted November 21, 2005 Thanks for the advice! So far I think she has been doing good. The temp stays in the 180-190 range. My heater is working much nicer and she warms up a lot better in the morning. -=fred=- Quote Link to comment Share on other sites More sharing options...

I ask because I have a bad temp guage and I am looking for alternatives. Quote Link to comment Share on other sites More sharing options...
fredrogers Posted November 22, 2005 Author Share Posted November 22, 2005 I went down to my local checkers and got a cheap mechanical gauge. Also be sure that it has a metric adaptor for it; I had the checker's guy open up 3 of them to be sure a got one that would fit in the threaded hole where the factory sending unit was. But if I where to do it again, I would get the one with the longer heat tubing for the sending unit. Mine was not long enough for a good mounting location so it ending up next to the center of the dash just down from the radio. I did find an easy way to route the hose though the passenger side gromet. To get a new factory one is $$. To get a new electric gauge is $$. Plus my problem is that my dash is unhappy (all sorts of electrical gremlins). Sooo... I just got a mechanical gauge and it's doing the job great! -=fred=- Quote Link to comment Share on other sites More sharing options...
