Been digging around old threads and its seems to be a confirmed facts that if you buy a Porsche AG waterpump, they cover 2-years unlimited mileage warranty, parts + labor.

However, I couldn't find anything on if the pump and belts had to be installed by a authorized Porsche dealer.

Was thinking of going this avenue and doing it myself.

Anyone know?

Anyone have experience with a WP failure where Porsche honored this warranty?

Thanks

I have read posts from at least two other people outlining how there was a failure (either here or on Pelican) and Porsche covered the cost of parts and labor to repair.

BUT, the repair and replacement was done at a Porsche Dealer, and coverage under warranty is dependent on what the Dealer Mechanic/s find.

If you put the parts in, and you don't all Genuine Porsche Parts, and one of the other parts fails, or you make a mistake tensioning the belts, then you will pay the full going rate for the replacement parts and labor. And you won't know if you are paying until after the work is done, and the decision made by Porsche.

A mistake made during assembly (under tensioned, or falling to retension during the tiny window for retensioning the timing belt), or the failure of a Non-Genuine Part (saving $10 on a belt roller when you didn't replace it, or bought it from Joe Blow's Cheap Europarts could really cost you). Just putting in a Genuine WP will not protect you from a broken belt failure (unless the failure occurred due to a seized Porsche WP, Porsche belt, or Porsche pulley or Porsche roller).

This is mean high anxiety, while you are waiting, and guarenteed high blood pressure before the final verdict comes from Porsche.

So the critical parts to keep genuine porsche are:
Timing rollers
Timing belt
WP

also, balance shaft belt and rollers are non-related in the event of a WP failure, right?

I am mostly concerned with the WP failure aspect of the warranty as it could lead to catastrophic engine failure. I want to be protected in that department.

Am I correct in believing that its the bearing in the pump that fails? Resulting in the timing belt from being thrown off?

My understanding is that when the water pump seizes up, the timing belt breaks and then all hell breaks loose with the valves, etc.

Everything changed in a full FOES is important.

If the oil seals leak, then oil gets on the belts, weakening them, and may cause them to break before the next scheduled belt replacement. So if you don't change the oil seals, there is an oil leak, oil gets on the belts, causing one or the other to break, or strip a tooth and skip, or stretch and break, and you didn't install Porsche oil seals, NO WARRANTY ON THE BELTS FAILING. If you don't replace the waterpump with a Porsche Part, and the shaft seizes, or the seals fail and coolant leaks onto the belts causing them to weaken and fail, AGAIN NO WARRANTY from Porsche. If you don't replace the rollers and pulleys with Porsche parts, and one or more fail or seize, and a belt/belts break or jump off. AGAIN NO WARRANTY. If you don't buy both belts from Porsche, and one breaks, AGAIN NO WARRANTY.

This is why Porsche will not automatically warranty every car that has a/some Genuine Porsche FOES parts installed. If you were to take your car in complaining that the Genuine Porsche Timing Belt failed and the engine is damaged, Porsche is going to insist on a teardown to determine the cause of the failure, and if they find a broken Non-Porsche Part, at the very least you will get stuck for the cost of the breakdown, and if you choose to have the Porsche Dealer make the repairs, you will be the full cost of the parts and labor.

So, don't think that replacing the waterpump will protect you against all failures between FOES because Porsche will pay for it. Some people buy all Porsche Parts for the protection. Some people buy some Porsche Parts, figuring that getting the critical parts will help protect them against failures between FOES. Some people buy all aftermarket parts figuring they will save lots of money, and nothing will happen anyway.

The way I see it, you look at the costs, weigh the risks, pay your money, and take your chances.
