2000 gas 3 cyl. Intake hot

Early 70's 2000 gas 3 cyl.

Starts easy, runs good for maybe 10 minutes. Starts to bog down, miss, black smoke out exhaust.

Discovered today after running it a short time the bottom radiator hose was warm but the top radiator hose was very hot. Radiator near full. Water was hot but maybe not as hot as the outside of the top hose.

Also almost burnt my hand on the intake manifold. It was literally just as hot as the exhaust manifold.

So what is going on here?

The waterpump failed a year ago (bearing, spitting water around fan shaft) and I replaced it. I do not recall if I replaced the thermostat (I assume it has a thermostat) but I'm sure I would have replaced it at the same time as the pump.

Ideas? Suggestions? Thoughts? Things to check? Things to look for?[/b]

Your post is the only one in this thread that mentions a thermostart. All of the others reference the thermostat.

Gas engines don't have thermostart, the top radiator hose is always hotter than the bottom hose when the engines running.

Think about it, hot water out the top hose to the radiator and cooled water from the radiator back to the engine thru the bottom hose.

65/ later Ford gas engines had coolant flowing thru a water jacket in the intake manifold to heat the incoming air and fuel, so yes it's going to be hot, matter of fact the thermostat is in the front of the intake manifold.

Check the air filter for blockage then check for proper fuel flow.

Timing? Dirty carb? My 960 used to get really hot like you are describing. Timing was off a bit and we cleaned the carb real good. It's fine now.

Look for a stuck thermostat. If it was that hot you should see coolant flowing into the radiator.

Thanks Mike, that was my thought too.
