Question about Hyundai Motor 2004 Accent

How Do I Change the Timing Belt on my 2004 Accent?

The dealer wanted $450 to change the timing belt which seems ridiculous to me. I can obtain a belt for cheap, but don't know how to replace it myself. Can anyone help? How would I go about replacing the belt myself?

    I should have clarified. The belt is not broken. Hyundai suggests at 60,000 I have it replaced. I'm at 59,800 and I'm taking a trip up to Ohio and back from Texas, putting on over 2000 miles in the process. I wanna replace it so I'm not being stranded somewhere because the belt broke. So, it's not broken, just needs to be replaced.

    For the most part, yeah. I haven't done anything like this before so it's confusing a bit. I've found the how-to manual on the HMAService site so that might be helpful. I just called AutoZone and they sell my belt and gasket covers. They'll also rent out the tools to me to fix it, if I don't have the proper tools. I'll copy this email for my father in law who will help me, and see if he understands what you are saying.

    Any other advice?

The timing belt is inside the valve cover. You have to remove the the valve cover gasket. Underneath that you will find the valves, the head (the top of the engine block). There is a pulley that is used to tighten the timing belt. The pulley is attached to the piston and valve timing. This pulley is usually marked as to where it should be positioned in relationship the timing of the pistons and the cam shaft rotation. This is what is referred to as stting the timing in the engine, and the timing of the distributor. Since your belt is broken the engine has lost track of its timing, so you might have to refer to a manual on your model of car to set the timing. You will also need to replace the valve cover gasket when you put the valve cover back on.

    Two corrections about my response.

    There are two types of timing in the car. There is the distributor timing and the cam shaft/piston timing. You are dealing with the later. Also I meant to make it clear that when you remove the valve cover you will most likely be destroying the valve cover gasket. So you will probably need to purchase and install a new valve cover gasket for your car as well.

    More clarification.

    The cam shaft(s) determine(s) the movement of the valves. The reason you need to get the timing right is that you do not want one of the pistons (that has moved to its highest position) to collide with the valves that might be in the lowest position. Also even if this does not happen the intake of air into the pistons as well as the exhaust coming from and already combusted piston cylinder must be timed so that the internal combustion for each cylinder is timed properly. Are you sure you don't have any valve damage from when you timing belt broke?

    Also, I meant to make it clear that the timing belt wraps around two key components. One is a pulley that turns the cam shaft(s). The other is a pulley that is used to tighten the timing belt so you do not have any slippage.

  • dimo65

    Then when you install the new one just make sure you keep the cam shaft pulley in the same exact position it was when you removed it. If you do this you will not need to refer to a manual in order to set the timing.

    Did you understand the rest of my comments?

    You should know that the valves are used to let air into pistons according to the order they fire. The movement of the valves (up and down) is governed by the cam shaft. The air/oxygen is used in the combustion that sends the pistons up and down, The exhaust from the combustion in the pistons then flows out into the exhaust manifold based on the position of the valves also. The movement of the pistons then turns your drive shaft, which then results in moving the timing belt. Each revolution of these shafts happens many times per second at idle speed, and increases with the RPMs. So that is why it is so important that your timing is set very precisely. Usually there is a position of the cam shaft pulley that corresponds to piston no.1 in the completely down position. But like I said when you install the new timing belt, if you make sure the cam shaft pulley is in the same position it was when you removed it, and you have not moved the pistons at all then you should be good to go. If you have anymore questions, I would be glad to help.

It is vitally important to change the timing belt BEFORE it breaks on these kind of cars, because they have interferance engines which basically means if it breaks you are screwed. When changing the timing belt (I would recommend the following)
(1) replace the water pump
(2) replace the alternator and other belts as they will need to be removed for access.
(3) check and replace the tensioner for the timing belt

Most good reputable independant shops can do this at a much better cost than the dealer. Just guesstimating I would put labor at around $300. That is based on a rough estimate of 5 labor hours. Could be more or less (more at a branded dealership)...

    Dimo65 has given you a LOT of information that is why I did not go into detail on how to change timing belt. In all honesty if you don't 100% know how to do this, and don't have a solid qualified mechanic to help you, I would purchase the parts, and have them installed somewhere. It is just not worth the hassle. If you go to a branded dealership (one that sells cars) they are going to be signifigantly higher in price on everything. There are lots of independant shops that do these types of jobs all day long for a lot less than dealerships.

Do I change timing belt 90k. And approx how much will the cost be

Timing belt change points vary, or at least the dealer recommended intervals do and can vary by 50,000 miles. The purists and the cautious say 40,000 miles for every timing belt but these days that goes a little too far.

The cost of the belt or the belt kit varies a lot from model to model.

The time a belt change takes also varies by a huge amount - from less than an hour to five or even six hours, consequently the cost can vary from making a hole in a week's wage to nearly wiping out a month's salary.

You should obtain a number of model-specific quotations from reputable local dealers and repairers, ensuring they have product warranty insurance in case something goes wrong.

Hi, what is the mileage/time required for 2004 Civic to change timing belt? With/without water pump? thx

I would change the timing belt approximately every 80,000 mi. This is a guideline only that I have used on my 1979 Honda, and it still seems to be the right mileage for changing the timing belt on newer Hondas such as yours.

My daughter has a 2004 Kia Optima with 82k miles. I don't believe the drive belt has ever been replaced. Is it overdue?

Are you talking about the accessory drive belt or the ignition timing belt?

In any event, if you're confident it is the original, then by all means replace it.

My point in asking about which belt has to do with difficulty of repair. You should be able to replace the accessory drive belt yourself, but you should consider having a mechanic do the ignition timing belt.

Good luck

When to change timing belt on 2004 honda civic

Honda reccomends timing belt change at 100k. Most Honda dealers like you to change the belt at 90,000 miles (90k). some auto repair places will want to change the belt at 60k but that is not necessary (Note: if in a severe cold or hot climate like florida or canada you would change the belt before 90k or if the belt is over 7 years old.. Good luck:

When is a good time to replace the timing belt/chain on I35

I35's do not have timing belts. They have timing chains and do not need to be replaced. The only Infiniti vehicles with timing belts are the J30 and the QX4. So whoever told you that you had a belt doesn't know what they are talking about.

2002 Hyundai Accent Problem

first thing i need to know is did the timing belt break?
second is are you sure you aligned the timing marks and after the belt tensioner was tight you rechecked to make sure the timing stayed where you had it.
next step would be a compression check to if a valve was bent whenchanging the belt
i have seen this happen and this engine is an interferance engine.
