pappers 50 Posted September 5, 2015 Report Share Posted September 5, 2015 Hi,Removed my a/c pump and bought the required belt from VW but it only has ribs on one side of the belt. I've checked elsewhere and the part number seems right but given that it has to run the reverse side of the belt around the water pump, does this seem right? The grooves on the coolant pump pulley are much less prominant than the other pulleys. Anyone experienced this? Cheers. Link to post Share on other sites
daveyboy 897 Posted September 5, 2015 Report Share Posted September 5, 2015 Sorry for jumping on your thread pappers, but I could do with knowing about this too pappers 1 Link to post Share on other sites
pappers 50 Posted September 5, 2015 Author Report Share Posted September 5, 2015 My best guess is that between the tensioner and crank pulleys & grooves, enough tension and guidance is provided? It appears that the shallower grooves on my water pump pulley have slightly flattened the ribs of the old belt a little.My concern is that the surface of the flat (outside) side of the new belt does not seem rubberized at all to run around the pulley....?

reynolds9000 26 Posted September 7, 2015 Report Share Posted September 7, 2015 I have deleted a/c on my 12v and am using a one sided ribbed belt. I will go double check but I'm almost positive my power steering pump pulley doesn't even have groves and the belt stays perfectly centered pappers 1 Link to post Share on other sites
pappers 50 Posted September 7, 2015 Author Report Share Posted September 7, 2015 (edited) Thanks yeah looks like its fine. The web says for low torque accessories or where the belt wraps the pulley well, single sided is good enough. Edited September 7, 2015 by pappers daveyboy 1 Link to post Share on other sites
daveyboy 897 Posted September 7, 2015 Report Share Posted September 7, 2015 I've deleted it on my 12v too but wasn't sure if the 24v was the same. Pappers have you got a part number for the belt? Link to post Share on other sites
