Water pump question

I was reading another forum that a Toyota tech mentioned
that the weep hole was designed to remove debris .If it is
just very small amounts then water pump replacement is not necessary.
Suggesting a flush and refill.Has anybody had any experience with this?

 

Mine was trickling out, not enough to drip, but left a thin line of pink crystals down the engine block. Dealership replaced the water pump under drivetrain warranty.

 

I find that hard to believe. I always thought that the weep hole was on the outer side of the bearing after the seal. IMO, if you see a drip, you have a problem.

I have never heard such a statement.The weep hole was an indication of pump
failure so I thought.But I am use to working on hot rods.

 

I wouldn't want that guy working on my vehicle(s). How can a hole remove debris?

Maybe he thinks it's there for debris to escape? If so, guess what else can escape? Coolant is a fluid and fluids flow more easily than debris and like electricity, will always seek the path of least resistance.

If you're seeing leakage at the weep hole, it's a matter of time before the water pump dies. It could take awhile, but it will eventually happen.

 

Seal is going bad if leaking from the weep hole.

 

If you have a leak/drip you have a problem.

 

There is no wet spot just a small amount of crust.
But here is the bulletin.T-SB-0117-11.Very interesting.
