Temp switches
Preparing for hot summer towing a small Scamp camper with our 87TD and reading all i can find about the borderline cooling system. I see references to Red switch,Blue switch,Grey switch for the aux fan switch. Does anyone have part numbers and temp ratings for these various switches.I have the dreaded #14 cylinder head that is OK right now and would like to keep it that way even if it means running the engine a bit cooler than maximum efficiency would require.I am on a dialup internet connection so cannot use the EPC and even if i could i dont believe i could look these switches up by color. All or any help will be greatly apreciated. TIA Don

No I don't.
However I don't believe that the difference between 195* water and 205* water will make the difference between cracking or not cracking, it is the pressure from combustion at full-throttle and the heat from combustion at full-load that conspires against the weak point between the combustion chamber and the water jacket. That area flexes, the more it flexes the faster the metal fatigues. Towing will accelerate its demise. Just opinion from other full-throttle water-jacket failures due to the pressure pulse from combustion.

You may want to consider adding a second radiator or replacing your existing one with a much wider core unit.

A larger radiator would be be pretty difficult in that car without altering the appearance of the car alot,so thats out. Someone on this board must know the information i seek on these switches PLEASE Don
