So, after around 4 years of doing nothing but home improvements projects to the old and new houses, I finally got around to doing a needed project on the old girl. At the time I put her back together, there was a coolant leak coming from the heater somewhere. Since it was close to the JCCS show and I didn’t want to deal with it right then, I just bypassed the heater. Fast forward to now and I got some time to address the issue. Doing some testing confirmed I had both a leaking heater valve and heater core! So out came the box and I first wanted to check the heater core. After getting it out and testing in a bucket of water while filled with air it turned out to be a small crack in one of the side tanks. A little heat and solder fixed that. The bigger problem is the valve. I know these are at this point basically non existent. I did have a spare heater box but of course that valve was also leaky. There are universal valves out there, but they are either cable operated or vacuum operated but the main thing was they all seem to be 5/8” connections where this car has 1/2” hoses. I know you can adapt the hose but I wanted to see if I could find a cleaner solution that would be as close to bolt on as possible, short of finding a NOS piece. Turns out the solution for me was in the garage next to the Subaru. A Datsun 1200 heater valve. While not a bolt on, it does have the correct 1/2” inlet / 5/8” outlet in a 90* configuration. Best thing is they are still readily available. Ordered a new one and swiped the one on the car to modify for the Subie. Here are the pics of what is involved in making it work in the stock location. Basically welded the 1200 valve to the Subie bracket.
