Purchased a genuine waterpump from Porsche AG.

If you notice, there is no polishing or finishing anywhere other than where it mates with another part

There is also pits in the casting where it mates to the radiator hose

Where it mates to the block, there are tiny pinholes, defects in the manufacturing

The body almost looks black where it has not been polished

So what's the big deal with the genuine pump other than the warranty?

Well, the pulley feels really solid, and i really have to get at it to feel any play.

However, only time will tell how this pump holds up.

Well there we have it, now we have on file what a genuine pump looks like.

You bought that waterpump from Porsche AG?

What did you do, go to Germany?

I take it that what you mean really mean is that you bought that waterpump from an Authorized Porsche Dealer.

Doesn't look like any New Genuine Porsche Waterpump I've ever seen. Maybe they've changed the finish since the last time I bought some. The ones that I have gotten from Porsche Dealers have all been natural silver smooth finish (no paint, and no matte surface).

Did it come in a Genuine Porsche Box, sealed in a plastic bag, with the Porsche Warehouse Shipping Label on the outside box? If not, it's not a Genuine Porsche AG Part.

Looks more like a rebuilt or reconditioned waterpump. I have never gotten one from Porsche that was painted black, or a new Genuine Porsche waterpump that had defects on the sealing surfaces.

Corrosion pits (like you are describing) on the hose sealing surfaces or gasket sealing surfaces would strengthen the theory that what you got is a rebuilt waterpump.

Casting/manufacturing flaws in the hose and gasket sealing surfaces are common on the generic manufacturer waterpumps and are a "Tell" that a waterpump is not a Genuine Porsche Waterpump.

PCNA (Porsche Cars North America) may be independently contracting with a waterpump rebuilder, which could explain the paint.

Or, the Dealer could have gotten that waterpump from an Independent Rebuilder (No Porsche AG Warranty!!!).

Did you get the warranty terms and condition written on the Porsche Dealer Receipt listing the waterpump?

I would take the thing back and get a replacement. There shouldn't be any defects on the sealing surfaces.

I bought the pump from Travis at Rennbay, who special ordered the part from Porsche AG in Atlanta for me.

The pump came in a box, no bag. It had these labels on it:

I ordered several other parts with the same type of packing labels and Porsche AG stickers such as thermostat, radiator fan switch. From ordering parts from the Porsche dealer in Walnut Creek, there are the same kind of labels I would expect.

The pump was not painted black. There was no polishing on the casts.

As long as the pulley is sound, then the pump shouldn't fail on me right?

Just my two cents on behalf of Travis, if he said it's a genuine pump, it is.

What was the damage (cost) for that pump, if you don't mind sharing?

$200 - $300 seems pretty cheap for a genuine Porsche AG waterpump. I would think that $500-$700 would be the going price for the real deal.

here in germany who get the choice to use the original porsche pump and second quality from the same manufactory ( lasso ) . I am not sure, but I think that the second quality has some plastic parts inside, which in at the original porsche one of metal.

we all uses the cheaper one of the free market. but like the the " rollers " of the drivebelt system you get what you pay for. here the free market rollers have a poor quality.
