Temp Question?

[MY 85 GT]

The new Mustang i bought its a 92 mustang GT auto..when driving the temp goes up..but idiling it will go down i forgot what causes that?...I really dont like the factory gauge either...it goes a little higher then the middle i was told it has a 190 t-stat also...im thinking of putting in a new radiator and a 180 tstat...any thoughts?

Bad ground. Check the ground cable from the block to the chassis. I just fought that same issue a couple of weeks ago.

Stock car doesn't need a 180 t stat it may run too cool with it actually . If blower is an idea then I'd do it . Like hoopty said check the ground . And also that the t stat isn't in backwards . That will cause it too

Really backwards ? Is that possible...lol.that would cause it to heat up while driving but go down idling.?. yes I'm going to put a blower on it just a 5-6 psi kit..not looking to break any records..

I would check the grounds first.

What grounds the ones behind the heads?

in general overheating when the car is due to poor airflow from a clogged radiator, bad air deflector, or a stuck thermostat. Overheating in traffic is a bad fan,, waterpump

First motor I ever bought. Intake was on it already . Used to get on the highway and run hot get off and cool . Sure enough someone said make sure the T stat isn't backward . And it was

Thats my thought im wondering if the Radiator is partial clogged I want to install a new aluminum radiator..i need to do a new AC condenser Anyways...it has a leak..Im looking into the SVT radiator..they look decent anyone have one? How are they?

If your radiator was clogged up, wouldn't it be hot all the time? I have a Champion 2-core radiator on mine. It was cheap and works really well.

Im thinking partial clogged thats why i think it gets hot when driving...cant keep up with circulation...But when i come to a stop it cools back down...I could be wrong...unless the water pump is no good...or the wrong one?

Definitely all possibilities. Check everything. The good thing about a cooling system is none of the parts are really expensive, so it makes sense to replace anything that is remotely suspect.

The previous owner just before i got it...replaced the water pump...hoses..belt, t-stat...Radiator i dont think he did unless it was a used one out of another car doesnt look new...

flush the system, refill with new 50/50 and make sure to burp the system and then go from there.

From experience... You HAVE to burp the system. I really like the thermostat housing with the burp hole. I used an old temp Guage sending unit with the head cut off and hollowed out with a hose clamped to a bucket. Works burping the system super simple

Lisle funnel. best $25 you will spend. no more jacking up cars to burp them

 

[MY 85 GT]

Why do you have to Jack up the car to burp the system?....

 

[elarm1]

To force out the air bubble. It's harder to do than you think!

 

[MY 85 GT]

I wonder if thats the problem then?...i know he did hoses..water pump...etc..wonder if he didnt burp it good?
