I just installed a new mechanical water temperature gauge in my 87 gl wagon.

 

What is the normal operating temperature for my car?

 

 

Thanks!

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.

I just put in a 192 thermostat, so . . .

Around 190 then?

 

What temp is "over heating" at?

 

Thanks for the info!

I would guess around 208 deg. F.

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

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.

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

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.

What did you use to do this? Is this like a factory water temp or did you use an aftermarket something?

 

I ask because I have a bad temp guage and I am looking for alternatives.

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!

Do you have a part #?

Here is a link to the gauge I bought.

 

Part #: 6142
