87-89 generator overheat

[omaopa3]

The flat radiator is hard to refill with coolant just by
filling the coolant tank. You must go under the rig and milk
the hose to eliminate the air pocket from the radiator. By
squeezing the hose you will hear the air bubbles returning to
the coolant tank. After you do this a few time, restart the
generator and watch the temp gage. If you start to overheat,
shut down and milk the hose again. You can also put a squeeze
on the return hose while gen. is running. I have gone through
this again when I recently replaced my hoses and did a new
insulation job. Once the air is eliminated, your radiator will
have an even temp. across its width.
