Thoughts on Water Pumps

[jrblackman]

My 2000 with 109,000 miles still has the original water pump, hoses and overflow reservoir. I have a leak somewhere near the water pump and given the age of everything I am not that concerned whether it's the pump, a hose or the overflow; I am going to replace it all. Does anyone have experience with the Gates water pump 134-09063238 from Partsgeek? It's $77.98 which makes me leary.

Thanks,

As I read more I have already decided against the one I mentioned previously but additional feedback is welcome.

Here are a couple of links that may help you decide. Have you decided what anti-freeze you are going to use?

Buy a Pierburg WP, they are same ones that come in the Porsche box for a bit less. It's not worth (in my opinion) trying to save money on anything to do with the coolant system in these cars.

Yup, I went with the Pieirburg.

Just changed out a cheap water pump with 6000 miles on it. There was play in the bearing.

Yeah, I may regret my gates WP but so far so good. I certainly have had good luck with their other products.

Here's my crappy rational...
My 84 Alfa Spider used to go through OEM Bosch fuel pumps at $250+ apiece. I didn't drive the car a lot so maybe it didn't like sitting. The pumps were whiny as well.
Well, in 2007, the car strands me again and just to get it off the side of the road, I buy a no name pump in stock at local Autozone for $159. I install the pump and the first time I turn the key to on, I hear nothing. I start the car and it starts up fine. 10 years later, its still on my car and very quiet.

Fast forward to the Boxster...Somehow a $200+ OEM WP that sees to fail around 50k miles (or folk seem to want to proactively replace) doesn't seem that impressive, hence, I'll try the crappy Gates pump and see what happens.

I don't expect my rational to convince anyone else, nor am I trying to do so.

Now in retirement, I figure my car will be driven 2-4K miles a year. Age of parts will be more of an issue than use.
Either way, since this is a fairly easy DYI, if I have to replace the part in the next year or two, no biggie.

Check the impeller on the old pump. If it looks like the blades have any damage, flush the system forwards and backwards like there is no tomorrow. If afterwards you see any high temps, cool it off and flush again. Cracked heads are no joke.

I ordered a gates from amazon as experiment, I didn't like the look of it when it came, had a metal.impellor (description said composite). I sent I back and got a pierburg, much nicer, felt smoother.

Also, while your in there, it is a good time to change the belt and motor mount if you haven't yet.

I replaced motor mount shortly after I bought the car and I replaced the belt a couple of years ago when I put the UD pulley in.

I put a WP Gates on my car in 2014 at $122K miles. Drove it about 1200 miles the next week back and forth to South Florida. I'm now at 132K miles (retired now and don't drive it as much). No issues.

It has a composite impeller, not metal.
