Water Pump, Help me
 

Hi, my name is Alex, I am new on the forum, I have a 2001 Porsche Boxster S and today, after hearing a loud noise, a friend checked my car and bad news, the water pump leaked and the pump was broken, with smoke on the pulley ... So no more car, perfect

I checked with 3 mechanics and their prices: between $800 and $900...
It's too expensive, and I just changed the convertible top ($1700) so less money for the water pump would be better !!

I find this Kit on Pelican Parts ($317.25), on the top of the link

What do you think about it??? The rating for the parts is very good

I don't know if there is a big difference between this brand and the genuine porsche?

Is Pierburg a good brand?

Can you help me please?

Thank you very much

FWIW, I went Porsche brand. Did it myself, about 4 hours.

For an OEM one from Sunset Porsche it is $255.88 plus shipping.

WATER PUMP | Genuine Porsche | 996-106-011-56

And a gasket for $8.88.

WATER PUMP GASKET | Genuine Porsche | 996-106-340-54

Yes it's perfect it's almost the same price but for porsche brand, can you advise me a thermostat because my friend told my that I have to change the thermostat too

Thank you very much

Pierburg is the really only brand outside of oem that is recommended by my indy shop. Get the oem metal gasket and you can do the thermostat while you are down there. It's not a too hard of job. I just did mine last month.

Your friend is partially correct in regard to the thermostat. You do not have to change the thermostat at the same time you do the water pump. The labor to get to either is redundant so it make sense to do both at the same time.

This is not a tough job if you can get under your car. You drain coolant. you remove the serpentine belt, hoses to the pump and then the water pump bolts. Clean the surfaces replace the pump, hoses belt and refill. Lots of good info on various sites on this job.

Alex....
When you change out the pump, you really should replace the coolant fluid too - but be prepared to pay.
1) When you remove the old pump check that the impeller is in one piece and not broken - the last thing you need is impeller bits in the cooling system.

2) If you are even half interested in keeping your new to you car for a long time, use the search function and read about "coolant" & "gelling" for a few hours. If you are not going to use the genuine Porsche coolant, you MUST flush the whole system to remove all the old stuff or you could get gelling - which is not good.

You will now hear some differing opinions.....

Jeez! How many beer breaks did you have :)

water pump is easy to change. if a little fiddly. Pedro has a walkthrough

Replace Water Pump

I didn't remove the engine mount, but pulled the seats and replaced through the inspection panel rather than from underneath. replace the serpentine belt as well.

And if the pump you order has a plastic impeller send it back get one with a metal impeller.

...not necessarily good advice. Do your research.

Went in from panel behind seat. Had to buy one wobble head socket. Then low temp stat. The I did all coolant. Then UD pulley, belt, done. I'm in no rush.

Metal impeller?? When mine failed, I knew because the bearing had allowed play and THE IMPELLER WAS RUBBING THE BLOCK OPENING where the pump sits. If it was a metal impeller............:eek: Which do you think will grind down first? The steel impeller, or the aluminum block? Aluminum in the coolant is not good.

Glad when I cut open my coolant filter and no shavings! Or fluid even??? Chicken feathers??? Oh, that was the cabin air filter.

Nearly everyone in the know has advised against metal impellers!

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 and thank you very much for all your answers

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.

Okay perfect, Im gonna take the parts separately but I can't do it myself, I know nothing about mechanic and I don't want to brake something or make a mistake, I just have to find a mechanic to install the pump
Thank you very much

I'm thinking about doing this project and appreciate the link. This step has me stumped. Why would you need to "trim" old gasket? :confused:

To install a new water pump gasket, it will need to be trimmed in 3 places as shown in the above photo. In order to remove the original gasket from the engine, you will also need to trim the old gasket in the same points.

The original gasket covered the water pump and item next to it with one gasket. If yours is original, you need to trim the gasket in the car, and trim the new gasket to just service the water pump. If someone has swapped WP, just trim the new gasket.
