Re: Serpintene belt question
Because some Vette owners are poor and can't afford the delete pulley ,
what we do is ditch everything ,
Install a std rotation SBC water pump and make a old style adjuster for the Alt
If you look at the F-Body belt diagram,the PS pump runs same rotation as crank
so in new setup belt runs Crank-PS -Alt -WP
Plus you get to remove any brackets and the idler on pass side to clean up engine bay
Might work for F-Bodies
( Appears Vette PS pump has opposite rotation so belt in F-Body would be under ; not over PS pulley)

Re: Serpintene belt question
When the water pump needs to be changed from reverse rotation (ccw) to normal rotation (cw), how can one tell by looking at the pumps what rotation they are? This is if one did not know the year or application and no pulleys attached.

Re: Serpintene belt question
The vanes on the impeller are apparently straight so they move coolant which ever way pump is turning.
Worth a try 1st to save some $$$

Re: Serpintene belt question
6 rib serp belts are generally listed by their length in mm
ie
6PK1550 where 1550 is the belt length
