anti freeze pukin out overflow

New member here, I have a 88 and it just started pukin anti freeze out overflow tank.I just put a new t stat in aand it still does it. Could it be the water pump? Any suggestions would be great. Thanks

Welcome!

It's over heating. You'll have to see if the radiator is blocked. Run the engine, not to over heating, and see if the entire radiator gets hot

Ok thanks. The motor never got hot it jus builds pressure and pukes out overflow and the anti freeze isnt hot. I will check what you said to do tomorrow.

Since it didn't get hot, change your radiator cap first, an easy, cheap fix.

OK I'll try that. It was running fine the other day then I noticed it was leaking antifreeze. Pulled it home changed t stat today and let it run and started flowin out the overflow.

I bought a new cap and still have same problem. Ran with cap off for a bit and didnt see any bubbles. I have a new t stat. The radiator never got hot. Could it be water pump? What should i try nxt? Thanks

did u make sure the t stat was going in the right direction

Yes put it in the same way old one came out.

Worst case scenario you have a blown head gasket, that has been my personal experience with my old Civic. As the others said, it could be a clogged cooling system, or a collapsed lower radiator hose.

I pulled the spark plugs out and they were wet. Would this be head gasket issue? The truck ran great and had no issues till the other day.
