Just had all my belts replaced along with the auto tensioner being swapped to a manual one and there seems to be a whining/supercharger noise coming from the timing belt area while accelerating.
Other then the timing belt being too tight Is there anything else that should be checked when I bring it in to a shop?

Almost every week someone will ask this question.

It is OK. Enjoy the supercharger sound until the belt gets worn in....I kinda miss it lol

I can't stand that sound, I guess I'll get used to it.
I've read a few other threads where people haven't had any whining noise after swapping the tensioner to manual and changing their belts over.
How many miles before it goes away?

I've been experiencing the same symptom right after the timing belt work was done. A few months later, I have manual tensioner swapped, the whinning noise remains there as soon as I shift in the gear.

I spoke to my mechanic who told me either turn on my radio a little louder or take his wife for a ride along will eliminate the noise. I went w/ the 1st option and seems to help.

same thing happened when I did my manual tensioner swap. I still have the whine 5 months later but its suttle....plus I dont hear it that much over the turbo lol

This is a good method to try and will eliminate some concern. It's a PITA to do sometimes depending on your application. Loosen and tighten the tensioner bolt, the one through the cover. I still think its a symptom of the belt being on the tighter side. But everyone says they are experiencing it. I am running the autotensioner BTW.

I bought the car in today and the mechanic adjusted the tensioner, no more supercharge noise.

E-Money

well did he take the covers off or adjusted it by my method?

angeloaa

To be honest I have no idea, I was looking through the Helm's Prelude manual while he was adjusting it. All I know is that it didn't take more then 10 minutes by the time he had the car hoisted up. The front left tire was removed.

Was this mentioned as being something that could cause a problem in the future ? or did your meccanic say anything about the belt being too tight resulting in a decrease of performance ?

this is my opinion:
The only thing I can think of is the belt may snap over extended period of time for being on too tight. It's more stress on it.

Mini, an experiened Honda mechanic/member here had told me when using the manual tensioner all you've got to do is pop the belt on and tighten the tensioner screw, no need to tension the belt up.
Personally, I couldn't stand the supercharger noise anymore.

Whoa, not that experience, just know my car like the back of my hand, I'm only 24, my dad was a master Honda tech though, most comes from hangin' out with him.

The average person really doesn't need a manual tensioner, the only time you'll see auto tensioner failure is with aftermarket cams or someone let the timing belt go for too long and it started leaking oil and very few that I work with have seen a leaking tensioner. There's a gasket that is replaced when you compress the tensioner each time you change the t-belt.

Question, does the auto tensioner also tension the balance shaft belt? I was told my whining was coming from the balance shaft belt being on to tight.
