timing belt replacement and timing

Just to add to this one because I work at a Hyundai dealership. On these models, for some reason, the belts all dry rot really fast especially the AC belt always starts to crack after about 30,000 miles. Typically when we see the drive belts really worn or really cracked, we recommend the timing belt as well. We use our best judgement when we recommend it not strictly based on mileage but also the age of the car. I've replaced these timing belts on these same exact cars with only 17,000 miles strictly because the car sits around a lot and nature does not stop for anyone so the environment continues to eat away at the belts. These timing belts on these cars are, in my opinion, the easiest timing belts I've ever done on any car. I can finish the entire job without rushing through it and put back together properly in around 45 minutes. My dealership charges about $425 I believe because it's typically charged at 3 hours labor because an inexperienced technician can take that long. I do them all the time so it's second nature. These cars have 2 drive belts and a timing belt. If you're a loyal customer to the dealership, most of the time they will try to hell you out and give you some sort of a discount. If you want to do it your self here is the instructions in the diagrams below. Check out the diagrams (Below). Please let us know what happens.

Well I've only gone there to buy the car and get a couple recalled parts installed so I don't know what counts as loyalty. 17,000 miles and the timing belt needed a change? That's only a little more than a year of driving. I Drive often which is part of the reason why I think I should do it soon. I was hoping if 60K miles is the norm I can have it changed once and be good for the rest of the car's life.

Yes only 17,000 miles but the vehicle was 8 was old. Hyundai recommends every 4 years or 60,000 miles. It's worth spending the money now if you plan on keeping the car, otherwise you risk replacing engine components or the entire engine. And no I'm sorry but only going to the dealership to get free work done wouldn't exactly count as a loyal customer.

Could they install a timing belt designed for a different car as that it is higher quality and doesn't rot as quickly? Is there a good reference to the highest quality cars out there so I can start researching my next car now?

No you can not install a timing belt designed for another car onto yours. Timing belts are vehicle specific. The amount of teeth they have, the tension of the belt, and the length of the belt. You can't go based on which vehicles timing belts last longer because it all depends on the manufacturer that makes the actual belts. A timing belt dry rotting or wearing has nothing to do with the vehicle itself. It's based on mileage, age, weather conditions. For example, if you live in the northeast, the timing belts wear faster because of constant climate change. If you live in like Florida, it's almost always a constant temperature which helps prolong the life of the timing belt. Northeast is considered severe weather conditions.

I change the timing belt and water pump and tensionner 3 week ago and now look like the t-belt move out of the cam gear I remove the upper cover and the belt move
Any suggestion or idea what could be the problem cause now the car won ´ t start.
Thank you

Was the tensionier replaced?

Yes the tensionner have be replace

If the engine was running smoothly before this happened again, I would double check the tensionnier to make sure it is good. It has to be allowing the belt to get lose and move.

The tensionner brand new from Hyundai

That is the part that keeps tension on the belt to prevent it from slipping.

Ok i will change the belt and at the same time I will check the tensionner but I wondered if the lower cover could be the problem I saw a groove at the bottom exactely face to face of the crank gear

Is the cover rubbing?

i had a new timing belt installed and now it makes noise at between 1000 and 1500 rpm. i had him also install a new water pump. The original serpentine belt was fine even at 78k miles. The tensioner was also fine. this is a 2007 hyundai elantra lim. auto 2 liter. my mechanic previously installed only a belt on my 2001 sonata 2.4 liter auto and it did not make this whrrring sound. It does not happen within the first few minutes then "comes into being" you really don't hear itonce your in the 1600 plus range on rpm's. Car runs and idles fine. I have only 300 miles on the new belt and my mechanic who checked it out said maybe to put another 300-500 miles on the belt and we'll check it again. I have had good work from this guy over the years.

I have had similar experiences with timing belts that I got a little too tight, that does not mean there is a problem, just a bit noisy. It may well go away as the belt gets some time on it.

When trying to time engine, the cam chain aligned crank aligned, but the cam pulley is pointing at 7:00 rather than 1200.

There are marks on both the chain and the gears to line up.

I was told it was time to replace my timing belt and have conflicting information as to whether or not I need to do the water pump at the same time. As far as I know, there are no problems with my pump. The question is, Hyundai says I do not need to do the pump, but a local mechanic says it is a good idea to do both. What should I do?

It's called insurance, the question is, why tear the front off the engine and not pay the extra for peace of mind? If you like to gamble, don't replace it! If it was mine I would!

I maintain my car diligently.

In December 2009 (one month ago) I had the timing belt replaced, a new radiator installed, and the valve cover gasket replaced.

My mileage on a subsequent trip decreased dramatically from 34 MPG to 28 MPG.

The garage that performed the work is honest and reliable.

Any thoughts on the cause?

THe only thing I can say is the timing could be off. However, even one tooth off will cause it to run very poorly if at all. Is it running good? If so, when was the last tune up?

Let me know.

Joe

Thank you, Joe.

Our mechanic rechecked the timing belt and teeth. He said they were fine.

Since then we have had to replace our thermostat since it was sticking open. Our mechanic said that if the engine is not running at optimal temperature (such as when the thermostat stays open), the mileage could go down. We are still monitoring the mileage after the new thermostat, but city driving shows no mileage improvement.

I changed the spark plugs last summer, and the mileage increased. I have not taken the car in for an "official" tune up because the mileage was very good (before our work).

The engine seems to run very well. It is just the decrease mileage since the timing belt work. Not sure what else to check.

Thanks again.

2002 Hyundai Elantra 4 cyl Two Wheel Drive Automatic

I had my timing belt replaced by a mechanic and every morning when I start the car, I hear a screeching sound for 2 seconds and it goes away and its coming from the timing belt part because I opened the hood and my wife started the car. THe noise can only be heard everytime I start the car in the morning.

The tension on one or more belts may be incorrect, the belt was installed improperly or they failed to replace an old, worn tensioner. Go back and have it checked ASAP.

most likely the noise is coming from a loose drive belt and not the timing belt. If the drive belts were not replaced during the timing belt replacement, they should have been double checked for tightness because old belts need to be adjusted tighter than new belts. By now the belts are probably glazed anyway so have them replaced.

My mechanic said that I should to replace the timing belt on the car as preventive maintenence.

Does anyone know what else is typically replaced/repaired when doing the timing belt?

usually the water pump, but you can hold off a little longer. If your nevous because it's an interference motor here's a simple trick to ease your mind. remove the top portion of the timing cover and do a visual inspection of your belt. if there's no oil, damage or stress lines on belt i would hold off. unless the car has sat or ben driven hard. But factory spec does call for the t-belt to be changed at 60000 interval. But i changed quite a few and usually they have more life than that. also if you want to take it a step farther you can spin the balancer so you can inspect whole belt. hopes this was informative.

My car is a four cylinder, two wheel drive, manual transmission with 194,000 miles. Having camshaft on TDC, please help me align timing belt sprocket (two marks on this, which one do I align to front of engine there is a hole in the sprocket, should it be at six o'clock?), and where should the valve cam marks be?
Robert

Okay, here is what I was able to find on the belt and chain timing marks and alignment. If there is more needed please just ask I will look for more. Thanks and hope this helps. Belt alignment

Chain alignment

With reference to your drawing for the engine timing marks above, I had this same problem with understanding these marks. I replaced the head gasket in my engine without pulling the engine out of the car and have everything put back together but cannot get my car to run. Do the cam shaft markings have to be lined up with the cam chain markings when the timing belt cam shaft pulley is at TDC? My crankshaft marks lines up with the chain marks but not when the crankshaft timing pulley is at TDC. Is that normal? The other thing I need to know is this. Since I did not have an engine hoist and did not pull the engine, the motor mount on the passenger side is in the way. I cannot remove the crank shaft pulley or the lower timing belt cover. have been using the mark on the crankshaft pulley to line up with the zero degree mark on the plastic TDC indicator on the lower timing belt cover. Is this acceptable for lining up the crank shaft at TDC? I do not know what I am doing wrong but if my timing marks are lined up right I can at least eliminate that as my problem. Thanks for your help!
