2003 Accord Whirring Noise in Engine?

Modern Honda 4 cylinder engines use a timing chain, not a replaceable
timing belt. The V-6s still use a belt.

 

Change they did. Honda's current 4 cylinder engines use a timing chain.
Many customers are really unhappy about having to pay for costly
timing belt replacements and thus many companies are going back to
timing chains.

 

My guess would be that it is either the accessory drive belt or one of
the things it runs such as the alternator or power steering pump.

 

I doubt it is the timing belt, but it might be the accessory drive belt.

 

you'd better hope you're right! when timing belts fray, they /do/ make
a whining noise. ignoring that costs real dollars.

 

it's bizarre that in a time of improving emissions control,
manufacturers would do that. as chains stretch, valve timing drifts and
so consequently, does emissions. belts don't stretch ans remain dead-on
accurate through their whole service life.

and car owners getting ripped off by unscrupulous dealers and repair
shops for over-expensive belt changes if not going to disappear because
of a chain - there will always be something else to hose the customer with.
