An over tensioned timing belt can make a humming noise. Did you follow the service manual procedure for tensioning it?

Too loose and now too tight.

Post a vid of the sound please

Hi Ron,
You've been a Great Help before with my Civic and I Greatly Apprecate It. Here's my question, Can I adjust the Timing Belt Tensioner without removing All the Belts,just remove upper cover ?

 

[RonJ]

It's a tight spot to work in, but I do believe it can be done.

You need to remove the black plug from the lower timing belt cover to access the tensioner adjusting bolt.
