How to winterize heater PCM 6.0

Recommended Posts

I am going to be winterizing my 2017 Axis (PCM 6.0) for the first time myself this year.  I downloaded the PCM online manuals and have the 7 drain locations for draining the block, transmission, etc.  which seems pretty straight forward.  I am not quite as clear however on how or where to drain the heater, can someone help me out with that?

On the back left of the engine there will be two hoses 3/4" just below the ECM. One of the hoses probably has a couple inch hose that PCM/Crusader uses close the loop at their factory and on boats without heaters. You disconnect these to hoses and blow air through the hoses to drain the hole heater look. You need to blow are through it so the water in the core of the heater gets out, otherwise it will crack the heater core. Here is a picture of the short hose that PCM uses. There will be two hoses here instead of the short one looped back.
