I have two failed aftermarket rebuilt waterpumps sitting in my garage that came off of engines that I bought to rebuild.

I also have an fresh aftermarket rebuilt waterpump that I refuse to install on my engine, along with a new generic waterpump that is so poor in quality that I refuse to use it. Both of these waterpumps came from eBay Sellers who misrepresented them as Genuine New Porsche waterpumps and refused to take them back.

None of the aftermarket rebuilt waterpumps or the new one are the same quality as even a Porsche rebuilt waterpump. So, I don;t use aftermarket waterpumps. You can choose for yourself, because ultimately you are going to be the one that pays.

And, yes I have bought aftermarket new and rebuilt waterpumps for my U.S. made cars in the past. None of them lasted as long as the Genuine original parts in those cars either. They were cheaper in the short run, but in the long run it wasn't worth the savings, when considering the shorter lifespan, and additional cost and time to replace them when they failed.

Dont forget, there are untold numbers of 944 engines with porsche waterpumps that locked up ruining the engines. Waterpumps will all fail. If there are well documented, consistant failures of an aftermarket waterpump before 90K miles, then you have got something. But only for that one brand.

well my car is done, to bad i cant drive it. im out of state visiting friends. i have to agree with gohim. ive owened several cars and most i have tuned to my likeing. ( 82corolla sr5.84celica gts.86corolla gts. 89celica alltrac. 90vw gti. 92mitsu gsx.) i still own the alltrac, and my belief is cuz i always used genuine toyota parts . i have seen several after market parts that r of verry poor quality. as for saving money and doing it your self. i know i can do it, i was a press mechanic for 20yrs repairing n rebuilding heidelburg press. i can even read some german. but the 2 yr porsche warranty is the clincher. its lasted this long with porsche parts so something is going right.

The reason that I only use Genuine Ford waterpumps in my 3.0L Taurus engines is because I only get about 25K miles out of the most common generic waterpump (sold under many different names) which is actually made by GMP. The lifetime warranty is not attractive to me because while it only takes me an hour to replace them, I hate taking the time (and the tow home) each time they fail.

Genuine Ford Rebuilt waterpumps come with a lifetime warranty (and believe it or not, new Ford waterpumps are 1 year warranty). I get 100-120K miles out of them, regardless of whether they are new or Ford Rebuilt. I have tried several different brands of generic new, and rebuilt waterpumps, and none of them last more than 50K miles.

As for waterpumps for the 924S, I have compare at least 6-8 different manufacturers, and remanufacturers, and I prefer the Porsche new and rebuilts.

Only a fool runs a 944/924S waterpump 90K miles, regardless of who made it or remanufactured it.

And, yes you could simply run your car till the belts break then buy another one, if you really wanted to. BUT, how long do you think the used belts on the replacement car you buy are going to last?

You choose to take your chances with generic parts of questionable quality, and perform the labor yourself. That's fine. If someone else chooses to buy Genuine Parts, and pay for Porsche Dealer Labor to get 2 years of unlimited mileage operation with a warranty, that's their choice, and that's fine too.

"Only a fool runs a 944/924S waterpump 90K miles, regardless of who made it or remanufactured it."


I have to agree with you on that. I have changed the water pump whenever I changed belts and Idlers. But there are a lot of sources out there who recommend changing the water pump every other belt change. Like Clarks for instance.

"For 944s it is unusual for a water pump to last significantly past 100000 miles. For that reason, I recommend replacing the water pump at every other belt change (90000 miles). For 968s, it may be possible to extend the life of the pump to the second belt change at 120000 miles. However, you should monitor for indications of a failing water pump closely after 100000 miles." -Clarks Garage

If you have information promoting such maintenance, paired with water pumps that make it only to 50K miles, you are going to have calamities. I have not heard of a “beware” brand 944 water pump with such a short life. If you have porsche engines with locked up aftermarket pumps you probably have absent minded owners. The same kind who have locked up engines with porsche pumps.
