Hey I just bought a real fixer upper 87 13b the body is super straight the interior is deace. Everything has been sweet so far. Until last week started over heating and loosing coolant. I have her up on blocks and I can't seem to find the source it looks like it is coming from deep within the engine the hoses all seem fine any Ideas fellas?

 

There's a few hoses behind the waterpump, and another in the back under the intake manifolds that could be leaking. The only thing you can do is to try to track it down by where it drips from.

 

The coolant hose that runs near the oil pedestal on the driver's side near the firewall is usually the culprit, as oil will break down the rubber over time. I'd check there first.
