Facts:
The OEM aluminum heater tee is known for going bad
The dimensions are too oddball to be easily found (5/8 x 5/16 x 5/8)
Plastic replacements suck
You can find them in stainless for over $50 (!)
You can build them out of plumbing supplies but it makes this piece large and unwieldy
Apparently there is an all-brass version from Midwest but I've never seen a price
So I present the cheapass heater bleeder adapter
Ingredients:
Four Seasons 84706 heater shut-off valve. These can be found at auto parts stores but I paid $8 Amazon Prime
5/16 NPT brass barb hose adapter (in I think 3/8 NPT?)
Directions:
Unscrew valve fitting from adapter body
Pull valve body straight up to remove
Insert barb adapter w/ thread sealant
Install in car
Treat yourself beer and pizza with those fat cash savings
