"Radiator Saver"

Never knew they made something like that.

I'm currently battling a dirty engine with a lot of rust and crud inside. I've already backflushed the radiator once and some hefty chunks came out, but still it didn't take too long to clog up again with finer stuff.

My plan is to get a rustdisolver and run that through the engine for awhile as the next step. Then do some more flushing.
