Default Re: Flushing engine block

One important detail to consider. If your plan is to only flush the engine with water you will not get the drudge out of the engine unless the water pumps are removed. All of the built up crud located at the bottom of the block will not come out due to the design of the water pumps. Even if you fill the block with any type of rust remover to get the junk out the pumps need to be removed. One plus you do have is the lower drain plugs on the block if you open those up some flushed material will come out. But with the pumps off blasting the block with water into the openings in the front face of the block will remove a huge amount of junk easily and fast.
