Hello,
I am adding an update to me Heater rebuild questions.
I pressure checked my heater core and flow tested it with my hose.
The core looked brand new and flowed quite a bit of water with my hose
check and did not leak under pressure. My heater valve looked great also.
As for the o'ring between the heater valve and the core. I used two
Nitrile 1/2 " x 11/16 x 3/32 o'rings stacked together. The replacement
o'ring I got from a popular supplier looked more like plastic than rubber.
Hnbr o'rings are very resistant to chemicals, temperature changes and have
high tensile strength. Having worked in aviation since 1970 this is my
choice. I thought about not reinstalling the heater, since I don't recall
the last time I needed the heater in my Healey, but I am trying to keep
somethings original.
