Quick question before install saturday...

SunburstGoldGT · Feb 12, 2004

Im gettin my steeda underdrives installed saturday and i was thinking about it and wondered since the sizes changed on the pulleys, would i need a different belt, but then i thought just the ratios of the pulleys changed, I need help because i basically confused myself trying to think of how they work. Also if i use the same belt, should i get a new one since i will already have the old off anyways?

Thanks

The crank pulley is smaller but the water pump and alternater pulley is larger. No need to change belt size.

Yes. In line w/ Coromprat the alternator & water pump pulley's are larger so they turn slower. That is what underdrive basically means. Due to the fact that the alternator & water pump are being underdriven there are now freed up horses. Running a smaller crank pulley allows it to spin faster, applying th freed up horses directly to the crank, increasing HP & TQ. Make sense? How many miles are on your car. I'm on my 3rd belt @ 43000, but changed to my 2nd belt @ 5000 cuz Ford thought my Throwout Bearing squeaking was my belt & I didnt' know better then.

Hey thanks for clearing that up guys, and DownSouth I have just over 42000 on my car and am still on the original belt, no squeeks or anything, but i think i might as well go ahead and get a new one for the install.

With 42,000 miles on the belt, I'd go ahead and change it. I change the belt on all my cars every other year no matter what.
