Eric,
There is a gasket that goes between the heater core and valve. It is not a round O-ring. It is a square seal. The part number is 861819297. 20.3 X 2.4mm if you need to source it. An O-ring will work.

Hi Stewart and others,
this sounds good and pretty straight forward. the one clarification I’m hoping for is that there is no recess on the core side of the connection to the hose at the top. this is where the core connects to the valve that connects to the top hose. If there is a place for a O ring then I hope it is on the valve and not the core side!
the more I know and can prepare before taking it apart the better!

The core will not slide out of the fan box when screwed down with the Westy seat installed, the plywood seat floor blocks it.

There should be a restrictor stuffed into one of the hoses, don't lose it, or all your hot water will circulate there leaving little for the front core. If there isn't one, leave the winter setting in the middle position on the valve.

I looked at the valve from my '85's heater (I did not install a new core), and I think there should be an O-ring between it and the core, but the recess for the ring would be on the core side. If the new core doesn't come with an O-ring or gasket, use Permatex "Right Stuff" sparingly to get a good seal.

>> I am traveling and can't look at my stashed-away rear heater for a procedure. But I can tell you that one of the problems you're going to have is keeping the rear seat in a position where you can work on the heater. This is important because not taking precautions could break your arm or maybe worse. You've got to hold the seat up with a 2 x 4 or similar, or else you need to remove the seat from the car. There may be some offers of shortcuts out there but it's pretty difficult to get the whole thing out with the seat in place. You can do it, but you have to hold the seat just right.
