Leaking Coolant when car shuts off

[Bloody Panda]

So I've noticed that my car leaks coolant out of the overflow when I shut it off. I was thinking that this might be a bad rad cap? Could that be the solution?

Pull the thermostat out ,, Some people with mods need a better rad or use high temp coolant .. Everyone thinks the faster you go the better, with out thinking about the cooling system just my 2 cents


Edit , Pull the thermostat out , to check that its working (opening and closing)

Do not pull the thermostat out!

If you need to do that then something is wrong with your cooling system, that needs fixed.

Definitely leave the thermostat in. It's warming up so maybe your car is getting cooled a bit less. Thoroughly check over the entire system, make sure she's full of coolant and that the coolant looks good and clean.

Yes try this. I've heard this is a great way to test it. Also, my buddy put a high performance aluminum rad in his subbie and it runs a looot cooler now. Make sure its double core.

T-stat is working properly. I guess it not hurting anything to be at the halfway mark, but It wasnt there before. Anything else to make it go up?

Its possible that your old t stat was rated at a lower temperature and now you have a stock temp stat.

It started with the old one, so that was the 1st thing I changed thinking it would solve the problem. Fail

If you changed the ECT sensor along with your old thermostat maybe one of them was bad and now with the new ones your system is working properly. If you don't see any signs of it overheating I wouldn't worry about it.
