Thread: timing belt noise

  1. #1

    Default timing belt noise

    so I did the timing and balance belt on my 99 accord 2.3L. At start up it's quiet and smooth. As it warms up it starts to get a whining noise and the idle roughens some. Ive done other timing belts before but never a honda. I didnt crank on the belts when I installed them. Any ideas or tips? Thanks.

    Check (and probably replace) the tensioner. If you didn't replace that, as well as the water pump, when you did the belts, then you really should go back and do it. Those things are likely at the end of their lifespan by this point.
    If those were replaced (by quality, OEM components), then check the tension on the belts and make sure they're not too tight. Too-tight belts can also make noise, and cause all sorts of expensive problems. You don't want to mess around with this stuff on an interference engine like the F23A. - 1990-1993 Honda Accord forum

    i did replace all the items you mentioned with aisin or oem parts. Turned out that the balance belt was a little too tight. readjusted and all is good. thanks for the reply.

    Whenever doing the timing belt service always hand crank engine with the spark plugs out, valve cover off , rotate crank counter clockwise 7 complete rotations constantly checking the tdc marks both on cams and crank , as well as checking the belt tention by using your thumb and pointer finger to turn the belt to 90 degrees it shouldn't go past that as well attended the 90 degree point should be fairly hard to go further , I belive the tentioner should be 40 pound ft, this is what I did on my 98 integra ls non vtec
