Did you just replace yours'?

In prepping my Jetta 2.0 engine for my Westy, I figured I'd replace
some stuff like seals and belts. I also figured I'd pull the coolant
pump. "Better now than later" I thought.

Got some advice on brand names for replacement and was advised to get
one with a metal impeller as the stock plastic one self destructs. I
pulled it and sure enough, the plastic was deteriorating! Not sure
why, but maybe something to do with a chemical reaction?

Neil.
