Hello, new to this forum I have a 1960's Michigan 55A series 2 with a 353 Detroit. Want to install a small cab heater as I am sick of being cold plowing snow. Question is where is the correct location on engine to install the 2 hoses to feed the heater? Picture would be helpful if someone could post it. Thanks for any help with this project. Bill

I would guess there must be a plug close to the water pump for a feed, and then back into the head some where. Do yourself a favor and put a couple shut offs on each spot on the engine. I remember being in a 125 Michigan loader that had a heater that ran off engine oil like Terrex rock trucks with the air cooled engines did. Almost instant heat.

It looks like the 53 water pumps had two ports right on top of the water pump housing. Looking forward from the flywheel end of the engine, the port on the right looks like the suction side, but you should tell by the casting that the left is the outside of the impeller, and the right goes toward the pulley and into the center of the impeller. That will be the return to the engine. The supply will be somewhere on the back of the head that's convenient (into the coolant, not oil:D), and if there's no ports there, then there should be one near the thermostat.

Iron River Michigan. Been there 35 years ago, the last time while I was living above Lake Superior in small town called Manitouwadge. Friends from Iron River use to come fishing to our place. You definitely need a heater to live in that area and plow snow in the winter. I worked on many Detroit 353's, will look for a picture of from waterpump end connection to back end of head. All the best to you.

On the flywheel end of this Cylinder head on the picture you will see the word CRAB written. Right behind the letter B of Crab is a steel plate with 2- 3/8 bolts holding it on with a gasket underneath to the back of the Cylinder Head . I have seen some of these plates with threads tapped into then for either a 3/8 or 1/2 inch 90 degree elbow threaded into it.
On the front end of the engine you will see one pipe plug visible on the top of the waterpump housing. You could possibly use this plug also or the one that is visible on the side of the Thermostat Housing. Heating these pipe plugs with a torch in the dead center and then quickly tap in socket and plug will break loose easily. I seem to recall that this is how I seen these units plumbed for a heater in years past.
Hope it helps .
