Water Pump, Help me - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I just did this job Friday night.

Pierburg equals Porsche OE. Pierburg makes the pumps for Porsche. Only difference is the box, the Pierburg I bought even had the Porsche part number cast and stamped into it. Same for the Wahler thermostat, but the Porsche part number casting was ground off of the housing.

Zerex G-05 coolant works well (as it does in all-aluminum Mercedes-Benz engines) if you don't want to shell out $35/gallon for Porsche coolant concentrate.

May as well change the thermo while you're in there since it's right next to the pump and you'll lose coolant anyway. Why do it later?

Avoid any pump with a metal impeller as that can cause engine block damage if/when the bearing goes out, while composite will not do that.

I did mine myself. I went with the plastic impeller option, changed the thermostat, coolant and front engine mount all at the same time. I got the care up on jackstands, took off the cover behind the seats. With the motor mount out it is very easy. Check out the DIY writeups do your research and decide for yourself how YOU want to proceed. I wouldnt pay those prices to get the job done.

I think the engine mount removal is personal preference. I chose not to remove it, and had no issues getting the pump out. Two of the bolts were a little slower going, but IMO not as difficult as pulling the mount.

Hi Deserion, did you buy the $317 kit on PelicanParts or others parts?

No, I ordered the parts separately through Pelican. Pierburg pump, Elring Klinger gasket, Wahler thermostat (83*C) w/ housing. Ends up being $21.25 less than the kit (if you use the Wahler 71*C thermo) if you go separate, assuming the kit's parts are the same. Also went with an Opti-Belt drive belt.

Same thing, I got a Pierburg WP and it has the Porsche part number on stamped on it.
I paid $190 for the WP, $52 for low temp thermo/housing/gasket & $3.50 for the WP gasket, no sales tax and free shippingh @ warehouse33auto.com

Don't know about you guys but I've never had a Porsche water pump last more than 60k miles. I'm on my 4th Porsche water pump on my 01 Base Box. My 02 S is now showing signs of leaking. It only has 50k miles.

I don't work on my pcars...so, it's nothing that I've done.

What's your average Porsche water pump life time?

The water pump bolts are different lengths. Make a template out of cardboard and push the bolts into it as you remove the bolts.

The two longer bolts go in the two holes on the WP that have the raised edge on the back to help line up the assembly in case you forget to mark them when you take them out.
