Yep, That's the one. Try to find which hose it is without the part number in hand. Doesn't matter here or Porsche PET PDF file. Nothing gives you an indication. The phrase. "water flange" is of no help. The way the parts guy at the Porsche dealer found it. Was to go to the service manager and get him to point it out. I went ahead and ordered from them as they are the ones that found the right part # for me.
Not fare to make them do the work and not reap the profits. Same price as Pelican anyway.
I need to get the water pump and that three legged hose for it next.

You've done a great service for those to come...I'm quite certain Wayne will appreciate it, as well.

I hope anyone that is on this search and needs this part. And finds this info helpful. Orders the part from Wayne. As it will be to his credit and his site that they found the information. I do order some parts from Wayne. The profits go to keep this great site up and running. SmileWavy

Matta, You may know the answer to this question. Or anyone else with hands on experience. Is there enough difference between the Genuine Porsche water pump and the Piergurg one. To justify the difference in price? Being that the Genuine is almost a hundred bucks more?
Thanks for your input in advance.
Randy

I can't speak from experience, but everything I've read appears the aftermarket pumps fail quite quickly. Check for posts from Jake Raby or JFP in PA for their expert opinions. Those folks have the experience and have seen many failures, so I tend to appreciate their guidance the subjects. FWIW, I never cut corners on my Porsches, as it could eventually lead to greater problems.

Kinda what I was thinking as well. Both of those folks advice for me is always appreciated and respected. JFP is the first one to advise me to do the S cooler and low temp thermostat. So off I go. If you wanna enjoy BBQ and a beer in ABQ. Come by anytime.

Thanks for your input Matta!

The oil coolers are upside-down.

Thanks Click. I have the S-Cooler out in my shop already. The T-Stat insert was delivered today to my house. I'll post a pic of what it looks like tonight after I get home.
Randy

Pierburg (actual name Kolbenschmidt Pierburg AG) is a German automotive component manufacturer; but I do not know if they are a tier 1 supplier to Porsche, or only do after market.

Here's a pic of the oil cooler and T-Stat insert as promised. You can see the tool that comes with the insert to put it in the stock housing. Water pump ordered and on the way. I went with the genuine pump.
JFP, Thanks for your input. As usual!!!

Anytime; glad to be of help. After removing the fasteners, be sure to lift the old cooler straight up and then slide a plastic bag under it before removing it. Even though the cooling system is drained, there is always some oil and coolant retained in the cooler, just enough to make one Hell of a mess on top of your engine, that will try to come out when the unit is tilted. Saves on clean up………..

Thanks again JFP. Will do.
Randy

Oh sure, NOW you mention it! ;)

I received the water pump today. The Genuine version. You can clearly tell, the impeller is made of metal with a flick of the finger. I will feel much more comfortable with that, than the plastic ones, some of the after market ones are. I'm not sure how the Pierburg one is made.
Still have to get the T-Stat hose and the water pump hose, related to the part numbers on this thread.
I think when done. I'll be happy, I went ahead and replaced all these parts while there. It cost money, yes. Piece of mind for me is worth allot.
I'll be posting the install of these and other parts. (AOS, associated parts) on another thread when everything is in hand and ready to go. It can be found at this link.

Nice, thanks for the photos !

Since when does the genuine pump use a metal impeller? According to both Jake Raby and JFP in PA, a metal impeller will do irreparable harm to the block when the bearing fails. Not sure which is worse, plastic lodged in the heads or a ruined case...either way you're screwed.

Matta, Not sure since when. But it sure rings like metal when you flick it with your finger nail. I'll tap it with something else tonight. Like a screw driver. But your observations brings me to another question. What is the typical life expectancy of the water pump? Miles or years?
Thanks, Randy

I have never seen an OEM pump with a metal impeller, and I've seen quite a few pumps over the years. The life of the pump is always a question; some seem to go on forever, others break up after only a couple of years. Because the failure of the impeller can result in little bits blocking vital coolant passages, preemptive changes have become more common in recent years, usually in the 3-4 year range, or when the cooling system needs to be opened up.

Well, I came home and tapped it lightly with a screw driver. It sure rings like metal. But I took it out into the daylight and looked at it carefully and it looks like brown die cast plastic. Not sure why it rings like metal. So I stand corrtected. Thanks for everyones help. Here are a couple more pics.
