I just repleaced the timing belt and water pump on a 91 accord. Now there is a whining noise only at idle that seems to be coming from the water pump. My friend's 95 also makes the same noise that started after he changed his timing belt, but we figured that was becuase he used a generic water pump. I don't think the belt is overly tight, so if you have any ideas please let me know. Thanks, Joe.

 

Make sure the belts not too tight.

 

check your belt tension yes but on a side note water pumps aren't very expensive so most people just replace the water pump when they replace the belt as well... Just a thought... if you're going to check the tension it wouldn't be to much harder to replace the pump and it will save your engine down the road....

 

tell me how you adjusted the timing belt and the balancer belt,,,,,,,,,,,,

if you get either 1 of those too tight , engine will whine at idle ..,,,,,,,,Also while you had it apart did you chk to make sure tensioners were not noisy >???
