Its very likely belt is one tooth off, when tension was applied on idler pulley cam pulley moved out of proper alignment. Here are instructions on how to replace the timing belt correctly. Here is a guide to help you step by step with instructions in the diagrams below to show you how on your car.

You need to be really careful with this engine. This is an interference engine which means rotating the engine when out of time can bend the valves.

There was one issue I ran into on the front bank cam sprocket it did not have a timing mark like the rear bank and crank sprocket so that may be the issue.

The only thing I could find online was going off the number 1 stamped into the sprocket and not sure if that was right.

Not if you expect to find out what is wrong with it. You can probably borrow/rent a compression tester from the local auto parts store.

When should I change the timing belt on a 2004-Honda Accord? I currently have 71,250. Miles on my car and the Tires Plus company is insisting I replace it now or my engine will be damaged.

Check your owners manual. I think the recommendation is to change it at 90,000 miles. I didn't change my until 115,000 miles on my '96 Accord. The problem is, if it breaks before you change it, it will cause a lot of damage that will cost more than just changing the belt. I'm coming up on 200,000 miles and will be changing the belt again. I'm going to try doing it myself this time. Good Luck.

You have to understand the risk here. If that belt breaks or jumps time while going down the highway, the pistons will collide with the valves and bend nearly every one doing major internal damage.

It is actually a chain on the 4 cylinders and should not need to be replaced.

Engine Mechanical problem
2002 Honda Accord Automatic 22,750 miles

When I took my car to the dealership for routine service, I was told that I needed to replace my timing belt. The car has only 22,750 miles on it, is regularly garaged, and has never had a problem. The dealership insists that the timing belt needs to be replaced every 6 or 7 years, irrespective of mileage, because "rubber degrades regardless of whether you're trying the car alot." Can this possibly be right? I got the feeling that they were just trying to make some money off me, because they know I know nothing about cars. Thanks for any advice you can give me.

The material that the timing belt is made out of will "decompose", so to speak, overtime wether it is being in use or just sitting there. Sort of like a tire dry rotting. Although 22k miles is an extremely small amount of mileage, 7 years is a rather long amount of time. I suggest having it replaced sooner rather than later.

Thanks for using 2CarPros. Com!
