I read many posts from doing a search and I am still confused with the best way to clean the engine block from rust and crud, with-out removing the engine and having it cooked.
I bought some prestone cleaner and flush which I haven't used yet, but I read many people use cascade dihwaher soap, CLR and even one with muratic acid..don't think I want to try the acid route.
The radiator looks good but I know theres a lot of junk in the block...Just looking for an answer
