2003 accord timing belt

I just bought a 2003 Accord LX (4 cylinder). Looking at the maintenance
schedule, I see a mention of the drive belt, but not the timing belt. The
timing belt is mentioned in the 6-cylinder maintenance schedule. Does the
4-cylinder engine have a timing chain instead of a belt?

If it does have a timing belt, should I use the service interval for the
6-cylinder engine (at 105,000 miles)?

 

think it has a timing chain....The V-6 still has a belt

The 4cyl accord have a chain drive for the engine... it never needs
replacing...

From Honda Canada's site, "CYLINDER HEAD AND VALVETRAIN
The i-VTEC engine is crowned by a compact, lightweight cylinder head made of
pressure-cast aluminum alloy. Its 4-valve-per-cylinder design has double
overhead camshafts activated by a silent chain drive to ensure extremely
precise control of the cam phasing. The cam drive is maintenance-free
throughout the life of the engine. The combustion chamber is designed with a
relatively large "squish" area that promotes faster flame propagation on the
ignition stroke. This results in more complete burning of the air-fuel mix
and subsequently, lower levels of Carbon Monoxide and Hydrocarbon emissions.
"

 

Definitely, the I4 has a maintenance free, metal timing chain. New for
2003's. Not to say you won't have to replace a high-mileage water
pump though, so the savings is largely fictional.

The V6 has a polyester fabric belt, still needs replacing at 105K
miles along with the pump.

Definitely, the I4 has a maintenance free, metal timing chain. New for

the savings is not fictional since the water pump is located external
to the chain case and driven by the serpentine belt.
a lot less labor.

I've just bought a 2000 Honda Accord 4 cyl and the only reference I could
find in the owner's manual recommends changing the timing belt at 105k. I
previously owned a 1991 Accord that required replacement at 90k. Does
anyone know why there's an extra 15k allowed for the 2000 model?

belt technology has improved in the past 15 years. theyve had 15 years
to work on the design and iron out any flaws.

 

Well first note that those milages are for "normal" conditions and driving
habits. The severe schedule, which is usually 60K miles, is suggested for
a variety of reasons and varies according to different model year manuals -
from the usual severe stop/start/short trip driving profile to temps
regularly above 110F or below -20F.

As to why they bumped it up to 105K miles, probably based on improved
materials for the belt, empirical testing and I have to think, partly due
to competitive pressure to reduce maintenance reqts. There are quite a few
other things which fall into that last category in late Honda models, such
as clutch fluid change, even brake fluid change and engine oil change. I'm
still trying to figure if I'd want to leave coolant in for 120K miles.

Thanks, guys, I've had it placed at 85k just in case, since I don't have the
maintenance records and won't take any chances.
