    Re: Back flushing motor procedure?

    Not sure by your post as to exactly what your trying to achieve.... but I'm thinking that you might be trying to backflush out missing impeller pieces??? Other obstructions???

    There were several posts just recently which go more into depth.. but to get you started if impeller pieces are the issue....

    Remove front and rear hoses of oil cooler. In the aft of the oil cooler, feel around for impeller pieces, if you don't find all that you are missing, flush water through front of oil cooler, then recheck aft of oil cooler again. If you look at front of oil cooler, holes are so small, most pieces of impeller will never get past oil cooler and if they do, they are so small, they will get exhausted out.

    If this isn't what your looking for, post more details....

    Good luck!
