The heater i have is actually an Air heater, and I'm just trying to scavenge the waste heat from the exhaust to heat coolant as well. I have two, one permanently mounted units that i'm putting in the machine and then one of those self contained ones in the red tin can. And using that one the exhaust seems to put out more heat then the hot air.I have installed a few of the diesel burning espar coolant heaters on 3306 engines and I either tap into the primary fuel filter or go right to the tank for fuel supply. As far as coolant hookup goes the 3306 is one of the hardest engines to get good ports for flow on. With the espar it has enough pump flow of coolant that you can tap into the heater hoses and it will heat the engine.
I would recommend you look into the espar or webasto coolant heater for your machine and then use that egr cooler with hot coolant pumped through it from the espar to create hot air to blow on the trans/ hydraulic area.
Another suggestion is if you are starting that hydrostat at -25 you should probably be putting arctic hydraulic oil in it.
I have noticed that there is not any larger coolant plugs on the injection pump side, which i was hoping there was going to be since its more open then the oil cooler side. Right now i want to stick with the cheap Chinese one because it only cost $220 and want to see if blowing warm air at the pumps, and then at the block will even help. The less electricity and power drain one has on the batteries in the cold the better. I have a constant drain on the batteries that i already can't track down, i have a feeling its the alternator itself. So i just turn off the master every night.
I run the cold weather 0w-40 in the engine oil, and then hydo 10 for the hydrostatic and hydraulic.
