Water pump recommendation
 

I know search is your friend but couldn't find. Any recommendations for a decent water pump for 00 box s?

ThAnks.

Lots to read, the general consensus is to stay away from any metal impeller pump.

simple

Get a pierburg from warehouse33auto.com
putt rennlist in the coupon code area when checking out and get an additional 10% off

don't forget to order a new gasket and coolant (3 gallons) that you dilute 50/50 with distilled water (walmart $0.88/ gal)

good idea to replace your thermostat while you are in there

also replace the bolts, I had one torque off at 7 ftlbs!

Thank you both? Any opinion on the manufacturer whalen vs LN engineering for a thermostat? Might as well swap out while down there.

Wahler? Sorry I think that is it.

Having dealt with third party pumps I recommend OEM only. Even the OEM pumps aren't great but third party failures are more frequent than OEM. The third party pump I used once lasted 2,400 mi. and you'll hear stories similar to mine a lot. I've heard, unconfirmed, that even Porsche are recommending a new pump at 40K miles as a maintenance service.

the Wahler is fine. It is a whole lot less $ than the LN and comes already installed in a housing.
Many also suggest replacing it with the low temp version. Lots of discussion on that.

Pierburg makes the Porsche water pump and the one I received had the Porsche number on it
I don't recall any issues or problem with the Pierburg one

drink whatever kool-aid you prefer

Also if you can, buy or borrow an Airlift for replacing the coolant. You will need a compressor to use it

There are a lot of water pump and DIY threads here as well as DIY on pelican. Do some searching.

And, and..... consider changing the motor mount while you're in there. It makes changing the water pump easier and they are a maintenance item.

+1

And makes it easier to tighten the one fiddly bolt on the WP, and with the coolant hoses loosened makes it much easier to get to the motor mount.

Thanks guys. Now do the motor mounts wear out over time or usage. Car has just under 50k.

Time ravages the rubber. If it hasn't been replaced yet it likily that it needs to be. Warehouse 33 got it for $174.

of if you have access to a ??ton press, you can just buy the insert for a lot less $$

I changed mine earlier this year when I did the water pump and other items. The Boxster had 26,000 miles on it. Here are some photos of it. Keep in mind the car is a garage queen, it is always in the garage and never driven in the rain. Like others have said, it's the age. Fourteen year old rubber under stress just doesn't hold up.

The part number is 987.375.023.05. It was $138.62 at Sunset Porsche.

This is a side question - but can changing the motor mount effect the stick shift and how hard it is to shift?

I had my clutch done in Oct 2014 and afterwards my shifter was the smoothest ever. Then in Dec 2014 I did the motor mount and I don't remember the timing exactly but for the last year shifting has been tight and hard. I also had the transmission fluid changed somewhere in that time frame.

What fluid was used? Probably not Porsche OE 75W90 gear lube. Go back to that, and it should improve. Worse on cold mornings?

Motor mounts on a Boxster are more critical for the trans vs a 911 (a 911 actually has trans mounts too) due to the mid engine set-up.

I think you meant to say "OE". OE does not equal OEM. For example:

OE= a Porsche water pump in a Porsche box

OEM= an approved Porsche part manufacturer, like Pierburg, NOT in a Porsche box, may or may not have a Porsche part number.

Third Party= someone who make water pumps, that does NOT supply to the Porsche supply-chain

Heck, even Jake Raby uses and recommends only a Porsche OE water pump.

Whatever you decide, just don't us a pump with a metal impeller, composite only.

I bought a water pump and am trying to plan out my next move. I loosened the belt and the bearing on the existing wp seems very tight, no wobble at all. From the top I can get to all the bolts that are visible. Are the two on the bottom the hardest to get off. 5 on top not so bad, how are the two that need to be accessed from the bottom? Also, how long can I leave my car on jacks. I will probably do over a week. Is that ok?

OEM to me has always meant Original Equipment Manufacturer which in the case of Porsche means it comes in a Porsche box with a Porsche part number on it. It may (and most likely is)be made by a third party company but is the authorized Porsche replacement part. I don't ever recall buying a Porsche replacement part (OEM) that didn't have a Porsche number on it.:cheers:

Raby doe not care what parts cost. When you have maybe $10k+ profit in a engine, it doesn't matter that much

Your first statement is false. I don't know about your second statement, because I am not privy to Jake's finances and margin structure, and I doubt you are too.

Read his old threads about water pumps. What I remember from years ago; he recommends Porsche OE water pumps, no after markets stuff, no metal impellers, no OEM stuff, only pumps with Porsche part numbers in a Porsche box. He developed or had one developed a few years ago, Very stout & robust. But, it didn't sell. Expensive. So he went back to OE Porsche, and recommends changing about every 4 years as preventive maintenance.

*All this was for the 986/996 and first generation 987/997. Wonder how this will play out for the 987.2/997.2 and the newest 981 and 991 with the DI and 9A1 motors??

Hopefully this will clear up what is OEM and OE. There is also a list of manufacturers that make OEM parts for Porsche, water pumps being one of them.
"OEM Porsche Parts�stands for "Original Equipment Manufacturer". Porsche OEM Parts refers to the company that originally manufactured the product for Porsche. When referring to OEM Porsche parts, OEM designates a replacement part that is made by the manufacturer of the original part from factory. Believe it or not, Porsche does not manufacture and produce many of the parts they use to build their automobiles. Like most carmakers they use outside independent companies to help them design the parts used in your Porsche. Porsche then puts the parts in their own boxes with their logos.

How do these parts become available to companies, like ****************************************, to be sold to the end user? After a certain time frame the actual manufacturers of these Porsche OEM parts are allowed to sell them to other wholesale distributors for resale. This time however they come packaged in a box with the name of the actual manufacturer of the part, not Porsche. Its not an inferior part its just put into a different package. In most cases the part will be identical with the exception of the packaging."

Do you really think he cares about $100 in the cost of a water pump?
The Pierburg pump is the same as the Porsche branded pump

As far as his profits, well it does not take a Rocket Scientist to guestimate what the profit might be. @ $20k+ for a replacement engine from Raby when other replacement engines are in the $8-$12k range it's not hard to figure that he is making $10k ish. Sure, Raby does more in his engines and does probably replace more components than some others, but he has even stated that he raised his price somewhat because of what the market will bear

I am not saying he is not entitled to make a profit at all, in fact he is 100% entitled to make whatever he can.
Is Raby one of the top M96 experts in the world, YES
Does he build a great engine, YES
Is he making major bank, YES

If you research his old posts on this topic, he will not use or recommend a Pierburg pump. Only a Porsche pump in a Porsche box.

Which could be any number of pumps supplied by OEM and authorized by Porsche to be boxed and numbered as a Porsche part. Porsche does not make water pumps they rely on a third party supplier and probably the one that gives the best price point. Jake Raby can call what he uses whatever he wants it is his business.

so what???
