“I use adaptors I made to circulate water through the block without having the radiator in the process.”

This is what I did to accomplish the above. Just some 1 1/2 PVC, fittings and 1 3/4 I D radiator hose. I was going to put a trap on the down pipe by the water pump. Just a “T” with a short piece of pipe and a plug to clean it out and screen at the pump to prevent the reentry of debris. My thinking was the particles would drop into the trap on their way down the pipe.I ended up just using screen at the pump. I brought it up to temp, 190*-200* and let it cool. Cleaned off the screen and flushed everything. Cold weather shut my project down but I’ll resume in the spring. I have a gallon of RUST 911, I’m gonna give that a go when it gets warmer.......Mark
