I just replaced the timing belt on my 2000 Honda Accord and it sort of
runs OK. I am not sure I did it 100% right. There is grinding noise
from the timing belt teeth now and then when the engine runs slowly. I
drove the car to work today on the highway and it runs fine when the
engine is up to speed. The Honda manual was not too specific on belt
tension. I took the car apart a second time and the belt tension
seemed OK. I am wondering if the belt will stop grinding when it wears
I was hoping to take a long Thanksgiving day trip, but I don't know if
I can trust the car. I could give up and have the dealer look at it
but I hate to give up.
Any suggestion on checking the timing belt installation and tension
Are you positive that the noise is in fact the belt? Did you change the
water pump? Does the Accord have a single "serpentine" drive belt for the
alternator, ac, and ps pump? If not and they are separate belts, you had to
remove them to get at the timing belt so maybe you have incorrect tension on
the alternator, ac, or ps pump. If so, the noise could be coming from the
bearings in any one of those. If you can get your hand or a finger in there
carefully while the engine is running, try touching the timing belt cover
and see if you can "feel" the noise. Check the covers, make sure they
aren't loose or vibrating.
I've done the belt twice on my 99 Civic. The manual shows the sequence of
installation on the belt pulleys: crank to tensioner to water pump to
camshaft. The tensioner pulley is then loosened so it springs back into
place and applies tension. The tensioner should move freely without
binding. The timing marks are then rechecked. Then the engine is then
turned about five turns. The timing marks are then re-checked again. If
ok, the tensioner is loosened 1/2 turn, the engine is turned 3 teeth on the
cam pulley, and then the tensioner is retightened.
I don't know if the belt itself would be "grinding".
