Has 2005 honda accord 2.2 diesel engine,a timing belt or a chain?

This is going to depend on which engine you have. The 2005 Accord 4 cylinder has a timing chain and is maintenance free. The 6 cylinder model has a timing belt and should be changed every 90 to 100 thousand miles which you do not want to skip.

Dont think Honda Motor Company would cover it on an 04 plate anyway, so get a second opinion from another Honda dealer, dont think it will need all of those parts either unless Honda have modified all of them which is unlikely

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)

Yes, it does have a timing belt.
Most peoplerecommend getting your water pump and timing belt every 100,000 miles, but i would take it to a mechanic and see if he believes it should be replaced. be weary though it does cost a lot, and some people will jump on this oppertunity like a shark on chum Some sites will sell 100,000 mile kits for cars. but its not a DYI job inless you know your way around a car.

i do believe that engine has a timing belt

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

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.

they say 105k so do it asap. dont wait get it done , a bad belt can screw an engine

It depends, 4cyl. is a chain, the 6cyl. is a belt and it is an interference engine. I have not done this one yet, but Hondas are never that easy.
