Water pump .....

[runjmc2]

If your coolant has not been properly maintained it may be acidic and wear/damage your water pump. It's not just the mileage….

Hi guys it's me again. Just wondering if any of you installed or had installed the Boxster water pump with the metal impeller?

The one in Pelican Parts is half the price of the composite impeller Porsche made.

Advantage of metal is that it does not shatter into multi pieces. Your comments please for metal vs. composite!

I have a 2001 Box base.

I've read here that the problem with a metal impeller is if it develops a wobble, the metal will start grinding away at your aluminum block...not good and very expensive.

Think that's the reason Porsche went with the plastic version.

I'm on this project right now. I decided to go with the plastic because

1. That's what was in there originally. (Or so I believe. I'll find out this week)

2. Shredding plastic seems a lot safer than shredding metal.

3. The low cost of the metal impellers really turned me off. While I believe the $100-$150 dollar pumps might be adequate for a year or two, I'd rather not have the thought of a cheap pump going through the back of my mind whenever I decide to take a road trip.

ETA: I went with the low temp thermostat for no particular reason other than it sounds cooler. (pun intended)
