there is a consensus on preventive water pump replacement on
987.1
engines.
but what about
987.2
DFI engines?
i see that the water pump looks completely different.
same preventive replacement proved to be required?
My 2010 failed with under 10K miles /18months. So different part - same crap. My only symptom was a squealing bearing when hot. BTW All
987.2
's are not DFI. Only 3.4L. Th 2.9L uses the same water pump.
Part nos:
water pump complete 9A1 106 048 00 (includes gasket, pulley and bolt)
water pump housing complete 9A1 106 038 04 (includes above plus seals, bracket. and a bunch of other stuff).
I'm trying to decide if I should buy one to carry around as a spare. Planning a long trip this summer. I've got about 40K miles on this one (my 3rd - but #2 didn't fail - the engine did).
yea, i'm talking specifically about S models DFI engines.
is yours DFI?
No, mine is a 2.9L. What does DFI have to do with it? Same pump on all 9A1 engines - including
911
. Pump doesn't care if there's an 'S' stuck on the back, or how the gasoline mixes with air. Since the pump is just a belt-driven accessory, failure isn't a function of horse power.
The point of my original post was that 9A1 water pumps still fail at a disappointing (but not suprising) rate.
My 2c is that in most cases a failing waterpump will give indications it's failing- noise, weeping coolant- distinctive smell. So I take the approach of watch and see rather than doing it as part of preventive maint. Maybe not a bad idea to have the spare parts if mileage is getting up there and you do your own wrenching. I recall some conflicting advice from the tech columns in Excellence, Pano. Some saying replace on mileage (can't recall how much) others saying watch it for signs. I'm in the latter camp. My
Cayman
R's pump failed (very clear bearing noise) at 20 something thousand mi. I track it quite a bit so maybe a factor? lots of high rpms.
yea, that makes sense to me :cheers:
I also have a 2010, 2.9L. I took the car to the dealer for some work to be done and mentioned that I heard a squeak when I first started up the engine. I thought it might be a belt. At 26,000 miles I was told that the water pump was bad. I was also told that

considers this a normal wear item. Another wear item is the shift cable. Mine broke at around 27,000 miles and I was stuck in the middle of an intersection.
Just laughable, isn't it? Or it would be if it also didn't put the occupants in such danger.

So, does

calling this a wear item mean they are not being covered under the manufactur's warranty? I have occassionally smelled what I think is antifreeze, but no sqealing sounds yet. I will be out of warranty in Nov is why I am wondering about warranty coverage.
My replacement was covered under warranty. Dealer service dept was aware I regularly tracked the car.
Yeah, I don't recall anyone getting denied warranty coverage. But if you're just past warranty, you might not get any help. I think they use that "wear item" excuse to fend-off criticism about the lousy quality of the pumps.
Also, there's CPO coverage and 3rd party plans to be considered. Don't know how that will work out.
Late response, but still relevant if you're driving one of these. Prior to getting a failure, the car will lose coolant and throw a coolant light. The light comes on before engine damage, but it's time to top up for sure. You can still drive the car...but I would drive conservatively..
..Top up with DISTILLED WATER and anti-freeze. Do not use tap water to mix anti-freeze. If you introduce minerals and the like into your cooling system, it's pretty hard to get that out later.
I wouldn't carry an extra pump. You can get one online quick. It can be delivered in a day or two. If I couldn't find distilled or deionized water, I'd get a tow rather than put tap water in the system. ...so maybe you just want to carry pre-mixed coolant? If you have that, you can top up when the light comes on and drive it quite a long way. It still pumps, but it leaks. I ordered my new pump the first time i got a warning light. Then I scheduled the repair at my tech. Had to top up another time prior to all being ready for the fix...After that? All good. No permanent injuries.
