acesneights1 Posted March 20, 2016 Share Posted March 20, 2016 I found a heater for my Tractor but for the life of me I cannot see anyplace on my Mack motor to tap in for heater hoses. Does anyone have a couple good pics of an ENDT 673 with heater hoses coming off it ? The Military TM's do not cover this engine with a heater kit. Thanks.

Freightrain Posted March 20, 2016 Share Posted March 20, 2016 Top of the water manifold and back into the water pump. Just remove plugs and hook up hoses. 1 Quote Larry 1959 B61 Liv'n Large......................

j hancock Posted March 20, 2016 Share Posted March 20, 2016 Buy the shutoff valve and install it in the back of the water manifold. Gives you the option of turning off the hot water during the summertime. Quote JimIt doesn't cost anything to pay attention.
