I was told I needed a new water pump. I bought a new one and as I was installing it I noticed the leak was caused by a loose bolt not a faulty pump. Since I was there and had already taken the old one 90% off, I installed the new one. Now, I am parting the car out and have one left over. It works and was used for about 40,000 miles. Does anybody need a back-up or cheap replacement pump? Willing to sell it at huge discount. $20 plus shipping. This is a Porsche pump part number 996106 101, not an aftermarket product.
