Overheating 3208 in a 90SP36

[Scott]

Hey Howard, the winter/summer switch opens a spolan that allows the
water to travel further through the chassis heat system, instead of
going through the hot water tank then back to the CAT (remember I
have a FC) This is the same as in a car when you see high temps start
turn on the heater. It helps but not drastically, but it does help. I
try that before the fan because the fan is loud. Since I had the
radiator work, water pump I do not see the high coolant temps.

A simple check of the radiator is to take a infared temp gun
and "shoot" the radiator in various places from top to bottom, often
times if the radiator has "stuff" that has settled in the bottom of
it (kinda common) it will show a temperature difference. Some
radiators are only cooling on 1/2 or 2/3 of the capacity of the
radiator. Hence high temps under slight loads and time for some
maintenace.
