A/C Bypass belt length for 4.9 I am wondering if anyone can tell me the correct length (and perhaps part #) of the shorter serpentine belt needed to bypass the a/c on a pre-northstar 92 STS 4.9L.
I have searched all morning and I came up with conflicting lengths and part numbers: 62 inch
-Gates 68411 74 inch
-Micro V 6PK1888
Also, is it smarter to simply run the shorter belt, or go ahead and buy the bypass pulley ( http://autoparts.pricegrabber.com/cooling/m/73760699/)?
If all else fails I will just use a string to measure, but I'm hoping someone has already done the grunt work.
Thanks in advance
Re: A/C Bypass belt length for 4.9 This was posted by someone a while back. Re: A/C Bypass belt length for 4.9 Thanks, that confirms two of the part numbers I had found! Hopefully it will still effectively spin the water pump since it is the smooth side of the belt, and the water-pump pulley is smooth.
I will give it a try. Worst case - I'm stuck with a useless belt.
