Overheating 3208 in a 90SP36

[Howard O. Truitt]

Scottt,
I have never heard of turning on the winter/summer switch and the aux. pump for
extra radiator cooling. How much have you seen this help. Do you need to have
the heaters in the coach turned on.
Little things like this is what makes this a great site.

Hey Bill, I would agree. In our 86FC when coolant temps approach 220*
I am hitting the winter/summer switch and turning on the aux pump. If
that does not help then the fan override is next. If that is no help
the I am looking for a place to stop. Something is wrong.

Believe me I know the cost of CAT heads,gaskets, rad cleaning, new
water pump etc. ($5k) Been there. Mike has a "lil speriance" himself.
I would tend to agree with him. The oil may handle the temps but my
CAT doesnt like em. Plus I ALWAYS cool the engine down before shut
down.

Anything I can do to help the old girl, I will try. She may be old
but she can still dance!
