SCWE (Special Cold Weather Equipment) Maintenance Manual

[Svenn Ryen]

Here are some more arctic kit pictures, this time the passenger side heater.

I have had the core replaced. The construction of if makes it almost impossible to be sure that all coolant / waters has been drained. Mine had a few minor leaks, but a new core has been bulit in.

The fan is driven by a two way fan...so that it can either be used as a window defroster or heat the passengers and drivers frozen feets. I the large outlet leed air throug the engine compartment in ducting an into drivers side.

The smaller heater mounted on the drivers side is only for window defrosting.

Hi Svenn

You raise an interesting point about not be able to drain the heater core unit. In reading through the cold weather equipment manual I don't find any reference to this problem or the need to always run antifreeze in heater equipped vehicles. There are numerous cautions about damaging the heater cores and about checking them for leaks.

Has anybody come across a manual or service bulletin referring to this issue?

Great to see actual photos of a heater unit, thanks for posting.

Special Cold Weather Equipment Manual Link http://canadianmilitarypattern.com/S...0Equipment.htm there was a page missing from this manual in my posting which Svenn spotted and I have now fixed.

Cheers Phil
