Can anyone explain to me how a head gasket job would fix the problem, if
there is no visible leak?

Thanks.

I'm curious to findd out what is causing this . Is your engine boiling
over? The mechanic said the coolant isn'nt flowing. one of the coolant
pipes is clogged with something.
I have been having a similar problem with my 84. it has new head
gaskets.
I just installed a new thermostat. Still overheating.

the radiator heated up , then it stopped. I'm going to disconnect the
hoses from the two main pipes today and flush water thru them. if it sat
a long time, like mine has, it's possible that the pipe has rusted
closed inside. Or the inside of the pipe is narrower due to rust
deposits etc.

The other thing I'm thinking it might be is the radiator. After all
these years sitting, they clog up.

That's what i think my problem is.
If you light flashes before the engine is warm, then it could be the
printed circuit has a component failure, or plug corrosion.
if you changed the sender, check that the wires are good.

i have several vehicles and i have found that time is not on their side
of they sit unused for years.
