Thanks guys. Appreciate the advice. I'll put a new thermostat in while I'm at it. Not sure what shape the old one is in.
I'm just doing minor maintenance things at this point, and trying to get the truck into a relatively reliable toy. I don't venture too far in it yet, not until I have a little more confidence in it.
The main thing now is to get the hoses replaced and get some new anti-freeze in it. Winter's coming!!
Thanks again.
