Leading evidence: 'plastic impeller' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'plastic impeller' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check whenever it is in' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

My 06 CS with 22,000 miles is in the shop getting the water pump repaired right now.

I am on my second pump ( leaking ) both replaced by CPO warranty thankfully.

Water pump found to barely be whining and was replaced @ 18,400 miles,
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The only car I had a problem with the water pump was the '06 CS, replaced at 22k no more problems until I traded it in at 65k +.
There seems to be a lot of water pump failures. Is there a consensus on a higher quality water pump replacement. I would like to replace mine sooner than later.
If you go by the latest
Panamera
Mag article "No" . They have a very bad view of aftermarket waterpumps and state the OEM is the best. That said they do show a few have Bearing and build issue problems but overall most OEM waterpumps are very good. Wait it out till trouble starts , a pre-emptive change just because you've heard about problems isn't the answer.. Hope yours is a good one!
Another problem is the plastic impeller. As they get old the plastic gets brittle and chips off the blades. If a big enough chunk comes off, it can block a passage and create all kinds of havoc. No one has come up with an alternative material so we live with a faulty design.
I asked
LN Engineering
about a better quality water pump. They told me there wasn't a better pump than the OEM pump. They recommended replacing it every four years. I am on my second pump ( leaking ) both replaced by CPO warranty thankfully.
Wow, I have 40K, 41K miles on my 2006 S and no problems yet....
BUT I had aftermarket mesh grilles put in front of both front Radiators and the center void protecting them from leaves, cigarette butts, and the like...
What else can Panorama say? I can't believe that the OEM water pump is the best out there after the history of poor engineering choices used on the Cayman. I remember a 24 hour Daytona when all the new 911s were DNFs after every single one of their water pumps went out.
Any parts site will have something that works like a Bosch, a Johnson or some other equivalent substitute.
The
Cayman
pump is the same across the 6 cylinder water cooled
Porsche
engines with the same basic block. All
911
except
Gt3
and Turbo have the same water pump.
That does not make it any better. I am not the "missery loves company" type.
My 06 CS with 22,000 miles is in the shop getting the water pump repaired right now. It's covered by the extended warranty.
It does seem odd that it can die with only 22,000 miles.
BTW it was funny to see water pumps in the Q&A in this month's Panorama. Two different guys wrote in about water pump failure.
The first tech's response was "this is a rare problem, just replace it when it fails"
The
next
tech said "they fail all the time, I recommend preventative replacement at 50k miles"
I have Owned #6
Porsche
products in the
Boxster
/
Cayman
line. The only car I had a problem with the water pump was the '06 CS, replaced at 22k no more problems until I traded it in at 65k +. My experience.
Cheers
The bearing failed in the WP in my Box last summer. It had just under 26K mi but was covered by the factory warranty. If the WP in the
Cayman
doesn't fail before my CPO expires in May 2013, then I'll replace it after.
Mine went bad on my 06 CS right after the factory warranty at 60k miles. The shop guy told me that in general they're good for about 60k. So far the second one has got me to 141k.
So the Warranty expires
next
month, took in for an inspection to have a once over. Water pump found to barely be whining and was replaced @ 18,400 miles,
2008 Cayman S
.
It amazes me they can go bad so quickly in these cars, but at least having the inspection saved me from a $1200 repair.
Yeah this is kind of crazy considering VW had the same problem especially with MK4 platform cars. Fortunately there were metal impeller alternatives. It's hard to believe
Porsche
could be so damn backwards about something so simple to remedy.
Mine was replaced due to the pulley shaft break. Examination of the shaft break shows discoloration at the edge that changes at the point where it was last attached before it came off completely. It was running fine without change in noise or vibration until it broke off completely. Also, the bearing seemed like it was moving without much restriction. The whole pump is nothing but a cover with steel shaft mounted thru a bearing and a plastic short bladed impeller on the other side. Not hardly worth the $300. the dealer charges for it.
My thoughts are that engine vibration and the vibration of the pulley/belt was just too much for the shaft material. I think the quality of the steel had a small surface flaw that was compounded until it snapped at 66,000 miles.
All fixed now,
-Steve
Mine went out earlier this month. 41k miles - and out in the middle of no where. I have no idea if this was the first. I hadn't had the car more than a few months.
Plastic. The bearing gives up, and then the impeller can contact the housing. Better to have plastic wear down or break than a metal impeller machining the housing.
55K on my original pump, always asked for a check whenever it is in... Just went in to replace an air conditioning system pressure switch that failed quite spectacularly...
and guess what slight leak noticed, so replacing it with OEM.
Glad to avoid a major failure situation :hilarious:
I had mine replaced on 2007 2.7 and the parts man, who I knew, said that there had been several changes in the pumps from
Porsche
. He did not know what was changed, but cited that there was supposed to be updates of some kind.
For what it is worth? Jim
Current PN is 997.106.011.05 - which suggests the 5th version. Google provided no results for previous PN's except for 997.106.011.02. So there's at least two versions.
