Ron, it could be, but I seem to remember seeing it on the right side. Anyway, it's always easier to do the flush thru the system with clean water rather than just draining the block. The hose method stirs up all the crud that has settled and gets it moving and out of the block. You can do the block drain as well. Pick your poison. Personally I like a power flush with the hose and engine running.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
