need water pump bolt pattern Reply #3 – June 25, 2008, 07:28:25 PM Well you could have noted the positions of each of the bolts as you removed the pump from the block. But since you didn't do that, your car is still sitting in my garage while you are driving mine!Just kidding, bro. I hope someone can help you out because I can't remember where they go and they aren't the same as the ones in my '87 LS.If anyone knows the answer to this question, please let us know. I tried a forum search to no avail. If you need pics, let me know and I'll see if I can get some decent ones. Thanks in advance. Quote Selected
need water pump bolt pattern Reply #4 – June 27, 2008, 05:10:01 PM No one can help? Does anyone know if we could just use trial and error? Like run the longest bolt into each place until we find the one it fits in? Then do the same with the next longest bolts? Quote Selected
need water pump bolt pattern Reply #6 – June 27, 2008, 06:59:33 PM Start any one with the pump in place...THEN keep swapping them around till only 5/8"-7/8" of each bolt protrudes from the pump... After most are correct, swap the original if it is a noticeably different length from the others... Quote Selected
need water pump bolt pattern Reply #7 – June 29, 2008, 12:22:53 PM Hey guys i hate to jack a post, but what is the rotation on our water pumps? Is it standard or counter clockwise? 86 5.0 ls cougar, thanks in advanced. Quote Selected
need water pump bolt pattern Reply #8 – June 29, 2008, 01:42:19 PM Depends on which side of the belt drives it. I'm pretty sure all serpentine belt 5.0 cars have a reverse rotation pump (pulley driven by smooth side of belt). If the pump is driven by the ribbed side it would be forward rotation. Quote Selected
