60 series cooling piping ??

[robertglines1]

I have engine out  of truck.  On top of oil cooler there are two 5/8 outlets--are these used for the water filter? or heater?.  2nd question.  I have a hot water supply for heater from water pump(pressure side) then where would be a good return place? there is a port to dump it back into suction side of pump.      suggestions welcome.  New territory here for me with this particular engine.   Bob

Hi Bob,
I'll try to attach pic of mine. One of the outlets was actually the return from the defrost/front heat system and the other one has a block heater in it.
Don't know if it's the same as yours, but thought it was worth a try....
HTH...Tim

On my Series 60 there is some sort of feed or return from the interior heating system where the block heater would normally go.  I have not added a block heater for this reason although I rarely start the engine when it is cold enough for a block heater.

I have a pipe out where Block heater is also. Not that in the end it will still be there. Heater return to basically bottom suction side of water pump. Last little details!!( in this area.)  Thanks.  Bob

Ok....what I came up with.  Take plug out of back of head for feed water(supply) then transfer pump thru heater then return to suction side of water pump.  I went and visited a local tour coach operator shop and talked to his mechanic.He said I prob would not get enough heat out of oil cooler connection for defroster and heat. I have the transfer pump that came with shell. Going to use  the fittings off oil cooler for water filter.  Just another hurdle when you change things from the normal.  Just plain busnuts!!!!!    Bob
