The ONLY upside to advanced auto is the 'limited lifetime warranty'. Man I cant tell you how many parts I might have torn up myself. Then took it to them and made a vauge statemnet like,"something is wrong with it, it doesn't work", and I got a new one, last up was my afermarket 70 amp alt. Batter teminals got accidentaly crossed(momentairily) fried the voltage regulator, 16volt engine running. I've returned 4 throttle switches, 3 fuel pressure regulators, 1 starter..... No one ever asked how it broke. I would tell them if they ask, but.... Is that dishonnest? I am barred from 2 local autozones, it wasn't actualy from returning so many parts, but the exchange that transpired between me and the mgr. when I was finaly denied a refund after 9 months of a 'limited lifetime waranty'. Needless to say, I called the regional managre and got 2 autozones in hot water in one day plus a $25 gift card. I am currently wondering if I am boasting or making myself look like trouble, or maybe just a bad mechanic(which I certianly am not, just accident prone when it comes to lifetime parts)There i go again. Sorry I couldn't help your thread. I am feeling less confident, as i am doing my waterpump this week. I bought the Hepu, and I am hoping it goes on easy. Thanks Kenneth
