Re: [DML] Water Pump Controversy

["content22207" <brobertson@xxxxxxxxxxxx>]

I've never understood the big water pump controversy. There really
isn't much of anything to go wrong inside a water pump. They are not
complicated pieces of machinery -- just a shaft that spins on some
bearings, with a pulley stuck on one end and an impeller stuck on the
other. That's it.

Of course the seal that the shaft passes through will eventually go
bad, but water pumps have always done that. That's how you know it's
time to buy a new one.

If the back is leaking, simply unbolt it and either replace the gasket
or make your own with a bead of silicone.

I suppose if the white metal (pot metal) casting wasn't any good, that
could be an issue. But I've never heard anyone complain about a PRV
pump body itself cracking.

IMHO, the big controversy is price. For any of my other vehicles I can
buy a brand new water pump $20-$40. Try finding a PRV model that cheap
(except eBay).

For anyone contemplating a non-vendor purchase: be aware that PRV
water pumps are made for two different backs, which I call "right
handed" and "left handed" (for the side that the big takeoff barb is
on). Ours are left handed, looking from the front. A right handed pump
has the impeller groove on the wrong side -- won't work with a stock Y
pipe. Be sure to get a pic of the back or inside of the pump before
you buy.
