any body have a detail schematic of where and how to hook up the heater hoses on a Cat 246 3034T engine it does have a block heater if that matters Thanks!
I think it may vary some with the age of the machine, here's a picture, looks like one line to the water pump inlet, the other to the thermostat housing:
Thanks thats what I was thinking as I can see 2 plugs that can be unscrewed in those locations,.. somebody else mentioned something different ( had to pull a freeze plug and tie into the block) which got me second guessing
