I have a problem i really cant figure out. I have a 2007 GV 5 door. The fan belt keeps jumping off at the water pump pulley. Then it would shred as its not seated on the pulley correctly. What i have done to try resolve the problem:
1. Changed the idler pulley.
2. Changed belt tensioner.
3. New belt not original though. Gates belt 5pk1650, from what i have been told that this is the incorrect belt size. Its suppose to be 5pk1645 which btw i cant find anywhere.
Any help would be greatly appreciated.
