Timing chain or belt for a 2004 Honda Accord

7 years change it

Honda uses a timing belt. It should be changed every 60,000 miles.

On Honda Accord between 2002 - 2010 all they came with was an 2.4L engine, all have timing chain in them, no timing belt

It depends on the engine. The 4 cylinder engine uses a timing chain, and is generally replaced every 150,000 miles (Honda doesn't give a specific interval) with the water pump (driven off of the timing chain) and timing gears. On the V6 engine, you have a regular rubber/steel belt, and it is supposed to be replaced every 105,000 miles, according to Honda. The water pump is driven off the belt as well, and should be inspected or replaced. (I recommend replacing the water pump anyway, just to save yourself any future trouble)

Are you sure you have a timing belt on 2004. Most new cars have timing chaines. I will check for you or just go to autozone or napa. they can tell you if you have a chaine or belt. In most car having timing belt., it can be changed around 120-140 k

Belt is better replace either about every 100.000 or you'll destroy the engine when it goes out

Belt is Better because it's easier to replace, therefore much cheaper

Chain is inside and in the oil bath so harder= more expensive

By the way. dealer says replace every 60K . 100K is a MAXIMUM

Your vehicle is equipped with a timing belt. It is due for replacement at 105,000 miles(168,000km)

chains are metal links and usually last the life of the car.
belts are fiber reinforced rubber cogged belts and need replacement about every 60 thousand miles or so.  Because a broken belt can result in catastrophic damage to the engine. Belts are cheaper, usually quieter and require less moving mass for the engine.
My personal preferences are chains. 

2003 and up Honda Accord with 4 cylinder engines do indeed have a chain and the V6 has a belt which must be replaced at 110,000 miles. Why? Ask Honda, they designed the engines.

your vehicle would actually have a timing belt on it not a chain. Honda recommends replacement at around 90k-105k (miles) along with water-pump ,tensioner and tensioner bearing, depending on climate and normal/severe driving conditions. they have had some issues with some of the hydraulic tensioners, 6 cylinder model, failing prematurely. Depending on the dealership ,and if you can show a record of adddiquate maintenance records (you have kept up on normal maintenance) and failure is not due to anything other than part failure, honda will most likely agree to a warranty of the part itself with you paying for labor cost due to fact of outside normal warranty specs.
