I recently replaced the impeller in the
water pump">raw
water pump of my
engine.
The good news is it now sends a nice, steady gush of water through the
engine.
The bad news is that it also send a steady stream of water out the sides and back and into the
bilge. I re-sealed the plate that covers the rubber impeller, but that doesn't seem to have helped.
I should say it did not do this before I replaced the impeller (which, because of brilliant design, required the
removal of the whole pump).
I'd rather not spend $300 on a whole new
pump, but I'm beginning to worry that it might be necessary.
It's an Isuzu C240
diesel. Any advice/ideas appreciated.
