Hi Svenn

Do you have the little one way valves for the primer pump? I may have just seen a source for them the other day.

Cheers Phil

Hi Bob

You are correct the filter horizontal on the frame has got to be one of the nastiest locations you could figure out just about as bad as many modern cars. You get to burn yourself on the exhaust pipe and dumb hot oil down your sleeve.

But the change over to the bigger filter mounted high in the engine compartment I think had as much to do with better filtering and a filter that condensation could actually be drained out of. There is quite a lot of information about the filter relocation in the Service Bulletins from the fact that they had a kit for retrofitting the earlier design kind of tells you that original horizontal locations was not doing the job.

Cheers Phil

Hi Phil

Funny you should ask about the one way valve. All tubing with a few exceptions on my kit has been removed, so please tell me, as I am in the process gathering the bits and parts for the kit.

I also have had no luck finding the small fittings that goes into the manifold for the primer kit. I have a NOS primer kit that will be mounted on my GPW jeep so i at least have an idea how they look.

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
