Head gasket 91 explorer. ?'s

[JC316]

Heads are likely cracked. Figure $500ish to get it on the road. If you wanna sell it, PM me with details.

I was just given a 91 explorer with a 4.0 v6. Everything on it is good, even the a/c and 5 speed. But it has a blown head gasket. The guy said he fixed it and it someone over heated it 2 weeks later and blew it again.

It will start and run, struggles to build RPM and feels really low on power. There is exhaust coming from the radiator cap as well.

What other problems should I investigate? How big of a pain in the ass is it to work on one of these?

take heads off get them resurfaced get new head bolts and head gaskets throw them back on an u should be good.

holy old post. and to the other replies, the heads are bad about cracking and have to be replace in multiple cases. They are cast iron, not alum.
