The engine block heater is leaking. It's installed in a freeze plug hole. Tighten a screw and the rubber expands and seals it, or did. Gonna pull it out and see why it's leaking. Could be a crack in the rubber. It's made specifically for this engine which is a 1981 so the rubber was likely 40 years old when I bought it.

The old Chrysler 318 engines had a problem with those plugs, and those compressed rubber plugs worked good. Later, the diesel engines on the Mercedes trucks (not as good as Int.) used engine block heater, as well as a starting fluid system. Did not work well below 32F IIRC, and so we often pulled them. International engines started better in cold.

never been able to tighten the fan belt.

If an adjustable as here, maybe grind some more space?

Alternator is the adjustment. Can’t extend it or the alternator hits the inside of the tilt front end/hood. BTDT
