ok thanks i hear what your saying because i also have a 94 Mercury Cougar 4.6l and i bought an powersteering pump for it from Autozone. Yes they gave me a LIFETIME warranty but the dam thing went out 7 days after i had paid a mechanic 125 dollars to put it on. I wont be driving that car for a while, lucky for me i can do my own alternator on my bonnie. But i think ill try the Ac Delco because i have their high performance spark plug and im killing anything that races me (V6 only). But thanx alot guys!
