Cooling system reminder

If you were ever considering FWC, please keep in mind your RWC engine is slowly rusting to death every day, every month, every year. The only way to arrest this deterioration is with anti-freeze cooling.

What prompted me to post this is I just learned the viable blocks for rebuilding that are returned to MMI as cores has fallen to roughly 50%.

Time marches on relentlessly.

Joe, If I could cobble something together successfully, anyone can do it. I completed my mark I FWC in about 2014..I ran with no t-stat and the undersized HX for years (I've always been a gauge watcher so no issue there with it running 185-190°F), and finally got the larger HX in 2020 (Mark II) and then I was able to put the t-stat back in and it settled in nicely about 165°F.

I do highly recommend upsizing the side plate like Neil and I did to 1/2" NPT and a 3/4" coolant inlet hose. It seemed to help a lot with flow volume. Everything else was 5/8" hose. One of the things I fought with the larger SenDure HX was the inlet from the head was on the opposite side, so it liked to kink the hose. On MkI with the gold cap, it was a much cleaner install.
