Timing Belt Replacement by jacktb
Aug 24, 2009 (7:18 am)

I would like to get some forum user feedback on the Elantra timing belt replacement. I have three of these cars, one of which is approaching 60,000 miles and due for the belt per Hyundai.
 
My questions are:
 
1)Does anyone have experience with this belt breaking before replacement? If so, what was the mileage and age of the belt?
 
2) Has anyone replaced the belt and examined it for condition? If so, what was the mileage and age when replaced.
 
I trying to determine a reasonable replacement interval. If it can go from 60 to 75 thousand miles with minimal risk it would add 90,000 miles of usage to the total of the three vehicles in 150,000 of driving for each.
 
At this point I am leaning toward replacing it at 75,000 miles, at which point I'll examine it and report to the forum.
 
Thanks. --Jack

One point of reference is that the same belt, in the same engine, has a service interval of 100K miles for vehicles sold in California. Not saying I would take it that long, but that is interesting.

I think that has something to do with CA state law and what they consider to be part of the powertrain.
 
I wonder how many of them have failed and been fixed under warranty in CA...
 
Oh and it's not the same engine, as any fine-print lawyer type will tell you. It's the PZEV variant of the 2.0L which of course means it's different (even though the difference probably amounts to very little realistically).

Yeah, it is pretty much legal-speak with regard to emissions. The CA version is microscopically cleaner, probably handled through the software tuning more than the mechanics themselves.
 
The local shop foreman for Hyundai showed me the emissions for an Elantra, and pointed out that the car could be run in a closed garage without ever reaching hazardous carbon monoxide levels. Not that he would recommend testing it, though!
 
Want to try a neat trick? If you have an Elantra with a trip computer, get on smooth level pavement, take the speed up to 50mph, and look at the instant fuel economy. With the tires inflated to 32psi, the '05 model GT would hold at 50MPG! This is what is referred to as the "sweet spot" where aerodynamics, power band, and rolling resistance all come into balance. Push just to 55mph and it will come down several mpg, but watching that little 2.0L do it's thing is amazing.

And that is the '05 Elantra, before the car got improvements for FE in the engine and transmission. I've hit that sweet spot on my '04 GT before, although I get closer to mid-40s on a real drive in real traffic on the freeway. The 2007+ Elantras should do even better. But at 70-75 mph, mid-30s is all I can get.

Yeah, at 75mph 32 was all the mileage I could get. Ran good at that speed, though.

Yes. The California 100K interval makes me think this belt will last a decent while past 60k. This is one of the main reasons I am trying to get more real-world data. --Jack

This is not directly applicable, but I had a strange phone discussion with a service writer at my local Mazda dealer the other day. My son brought his school car (2000 626) in for an oil change (and that's ALL). The car had 105,000 miles. I knew exactly what they'd say, so I told the service writer when I made the appointment that the car is not on the normal service schedule, it had the 60k service including timing belt at 84k miles, and had the 15k service at 99k miles and an oil/filter change at 102k, so all it should need is an oil/filter change. So what happened? My son told me they tried to convince him the car needed a new timing belt. I called the service writer and asked why they recommended a timing belt replacement. Did they inspect the belt? No, she said 105,000 miles is the recommended change interval for that car. I told her that was odd, because I thought the interval was 60k miles and in fact when I negotiated to have the 60k service done (at another dealership) at 84k miles when I bought the car there a few years ago, they included the timing belt replacement. If the belt could go until 105k, why would that dealership change it, on their dime?
 
I have nearly 45k and 5.5 years now on my '04 Elantra. I plan to run it to 60k, which will be about 2.5 more years, before I replace the timing belt. I am sure the dealership will tell me when I bring the car in for its 45k service in a week or two that it needs a timing belt replacement "at five years or 60k, whichever is first." We'll see.

If you're still covered by the 10/100 power train warranty, replacing the timing belt is required to maintain warranty coverage for that portion of the drive train that relates to the belt. If you fail to replace the belt on or about 60K (assuming non-CA) and it breaks before the warranty expires, Hyundai can and likely will deny warranty coverage of the repair. And since a broken belt will take a good chunk of the engine internals with it, that's a very expensive repair.
 
Now, you don't need to replace it early, and can probably get away with waiting a thousand or two extra miles to get it done, but I'd advise you to have it replaced close to the schedule noted in your car's manual. To ensure you're getting a decent deal, call around to local places as well as the Hyundai dealer; any trained mechanic can do the work.
 
Also, generally, unless the other belts have been replaced recently, pay the few extra bucks and have them done at the same time. Many places won't charge any extra for the labor (just for the parts) as they're in there already.
 
After the warranty is up, do whatever you want. Stretch to 90K for replacements, for instance. But it's in your own best interest to maintain warranty coverage.

Thanks for responding with these valid points. Responses to my original post are designed to give me data on it's realistic life span. Specifically, I would like to hear from someone that has had this part fail. I cannot find any of this information so it is assumed at this point that the belt is designed to go significantly past 60K.
 
I'll probably follow yours and the manual's advice during the warranty period. The feedback will help me for the next time. Thanks again. --Jack
