Rebuilt water pump

[DWBOX2000]

Any thought on them? Worth the risk?

[itsnotanova]

no,no,no,no, and no

[jdraupp]

If Woody says no, it's no.

You have to weigh the PROS and CONS when making any decision.
The PROS: oh, there are none.
The CONS: I can't believe anyone would seriously think about it?
After analyzing the data I think the answer is NO.

You are joking, right?

Its a relative easy DIY
Get a Pierburg WP, they are the same as the Porsche branded ones

[DWBOX2000]

No joke. I didn't know the answer so I asked the question. Glad your not my teacher.

Thanks everyone. I have my answer.

Plastic or metal propeller?

Composite is the term(plastic). Go with the pier berg pump on pelican it's the oem manufacturer for porsche without the Porsche label.

If you search metal impeller on this forum you'll see why you don't want that metal impeller anywhere near your 20k dollar motor.

[rick3000]

Absolutely no. Get a Pierburg, they are Porsche OEM.

Maybe if you had done a search a bit you would have found out the answer to your question about using a rebuilt WP as well as metal vs composite impeller

In any case, best deal I found for a pierburg WP is at
warehouse33auto.com

If you enter the coupon code RENNLIST at checkout you get a 10% discount

don't forget to get the gasket and you probably will need that virgin unicorn sperm Porsche calls coolant. it runs ~$40/gal and you need 5-6 gallons diluted 50/50. Might as well replace the thermostat while you are in there

I paid $190 for the WP, $52 for low temp thermo/housing/gasket & $3.50 for the WP gasket, no sales tax and free shipping. Coolant was ~$40/gal as well

Hi DWBOX2000, I was at the USCG station in Scituate back in the early 80s. Nice little town then.
I tried to save a little money buying a water pump a year ago and bought one on Amazon. It stated that it had a plastic impeller, but when it arrived it was metal. I installed it anyway, but plan to replace it early. As all have stated: buy Pierburg/OEM with the plastic impeller.

Here's a few good threads:

....and for the gasket, use the coated metal style with no sealant. With these engines, gasket sealant has a tendency to squeeze out of the seal and become debris in the coolant passages.

I got my 3 gallons of coolant from Suncoast and mixed with 3 gallons of distilled water, and did a low temp thermostat at the same time, and pierburg WP. There is a good article on Rennlist on how to easily bled every drop of coolant out but I think it may be 996 specific, but there may be some parts in there applicable to us:

Simple 3-step complete coolant drain (updated w/ refill procedure + water pump tips) - Rennlist Discussion Forums

It is for 996 so the hose routing and stuff may be different enough that it does not apply to us, but I thought it was pretty interesting.

The USSG is still there. Thanks for your service. We have been in scituate for 20 years, still love it.
I'll read all this stuff tonight, thanks again everyone for the input.

Ok, I'll be in the minority here....I bought a gates WP for $72 and installed it (with metal gasket and OEM thermostat) a year ago and immediately drove from Panama City Beach to Ft.Lauderdale and back. As easy as the DYI job was, I'll keep an eye on it and change it out again if it fails.

FWIW, my old pump did not fail at 126K miles. I could tell it was original as the original gasket was in place. After I got into the job, it looked like all that was wrong was a little weeping from one of the bolts. I replaced it anyway as I had it all apart. Upon inspection of the OEM pump there was no wobble or noise from the shaft or bearing. Given the 7ft-lb torque requirement, I'll bet I could have snugged up the bolts and been good to go!
