Hey guys I have coolant coming out my overflow tank. What could be causing this it has new water pump and cap. Could the termostat cause this

 

Hope it ain't a head gasket. It checked the oil and it's not milky or anything

 

What year and what engine?

 

It really helps if you fill out your used CP so everyone knows what you have, easier to help you.

 

It's a 96 Cherokee 4.0

 

Pretty much all my cooling system is new, water pump, clutch fan, electric fan, radiator cap. What isn't new is thermostat and radiator. One of those two cause my problem?

 

Yes, I had this same problem. I ended up replacing everything except the radiator. Of course, it ended up being a clogged radiator. If its the original radiator, replace it as well as the thermostat and it should fix your issue.

 

I was told that it may be my head gasket

 

Better get it into gear and replace that then. What the hell do we know..........

 

Did you burp the coolant system ?Are you sure your radiator isn't clogged ?

 

No how do u burp the system on these 4.0s

 

You don't need to.

 

Ok good.

 

Overfilling is one possibility. It should normally be about half full when cold. Filling it to the top will pretty much guarantee and overflow.



No.

 

Bad radiator cap can cause this.
