Timing Belt Longevity - mileage or time?

We had our 2005 Odyssey timing belt, tensioner, water pump and valves adjusted back in June 2012 with about 100K miles. The minivan is now at about 190K and 7 years after the first timing belt replacement. The parts are Honda for the timing belt replacement work by the dealer. 95% the drives are short local trips about 10-15 miles.

Will this timing belt last for another year which will get us to about 102K miles for this belt and 8 years? How long does the timing belt last? Is this years or miles? Or should we replace this belt soon? We just did the LCA and the engine/transmission mounts and wanted to spread out the cost.

Beyond, the parts above, we are thinking of changing the thermostat, spark plugs and spark plug tubes. While the tech is working on this, are there other preventive things that we should replace since he is already in there? Heard about cam shaft seal, crankshaft seal or oil pump seal? If the work is not that much, we rather have it done ahead to avoid paying for the tech to go back in there.

We are getting P0420 on a weekly basis and might have to change out the catalytic converter behind the engine. Any benefits on this work and the timing belt? Are there any recommendation on the various flanges or clamps that we would need for this replacement since everything seems to be rusted?

We had one of the spark plug re-threaded about 80K miles ago. Have anyone seen issue with changing out the plugs with the re-threading?

Apologize ahead for the many questions above.

Thanks,

Timing belt longevity is both years and mileage. Typically 100,000 miles or 8 years. Which ever comes first. You should have confidence in getting another year out of your timing belt and ancillary components.

My opinion on this question: I think the timing belt will be okay to leave for another year. Honda's 7 years/105K miles service is a line in the sand, not a brick wall. It's slanted to the conservative side.

Also, failure of a timing belt support part (tensioner, etc.) is more likely to cause a failure than the belt itself. Luckily you had those replaced at the last service (although you didn't mention the idler pulley?). Not every job does.

If it would make you feel better there are little view ports in the cam covers you can pry off and inspect the belt. Wont reveal everything but worth a look. Extreme heat and cold cycling are bad for the belt. If you lived winters in Alaska then summered in Arizona I would say youd get 3 years out of it. I would also say yer crazy. Im in san diego got 129k and 12 years out of the OEM still looked great but we have mild weather.
One thing you can do while its apart... both pulleys on the serpentine belt tensioner can be repacked with grease using a grease needle. No damage to the seals at all.

It’s hard to judge the condition and remaining life of a belt by visual inspection. Also, it’s often the other timing components that fail before the belt actually fails.

I have 2010 EX-L with 60K miles, should I get the timing belt, tensioner, water pump changed ASAP? Am I living on borrowed time? A accident waiting to happen?
Dont change a timing belt , it is wasting your money ,i just change a timing belt on my 04 honda odyssey van , at 170,000 K mile , and the belt still look at branch new , no teeth missing and the letter of the honda still on it , you can see that logo , it fade away but it still there , so i suggest the belt it should last 270,000 mile easily base on the timing belt i just took out , dont scare them

You should make this a priority to have done soon, but I don't consider it urgent. You are due based on age.

Be sure to get the Aisin kit from Rock Auto - less than $200. As said, don't buy it from Amazon or eBay, and don't even think about some other brand.

On my 2010, i replaced it in end of 2020 with 100k miles in it. I used the Aisin Kit from Rock Auto. Almost 2k miles in it now. Coolant, i bought 2 gallon Honda fluid.The serpentine belt + tensioner was already replaced around 80k (because of noise issues). I also replaced the tensioner and pulley bolts and the thermostat.

Just like others said, no way to find if the belt is ready to break or not. For me, there was no issue, just changed it because of age/mileage.Me and my friend compared the old belt with new one and other than the color change with the mileage / heat, there was no cracks or anything like that. If it starts making noise (bad tensioner), replace it asap.

Thank you all for your quick response. I don't plan to do this job myself. Honda Dealer is saying it will be $1,950 before tax to have the timing belt, tensioner, water pump changed.

I am thinking of have a local shop do it instead. Is this something any shop should be able to do? How long will it take?

If you still want a dealer to do the work with OEM parts, you can call a few local dealerships to get several quotes to compare. We checked with two dealerships that are 11 miles apart, both of which are near our house. One quoted $1800 and the other quoted $1075.00 including parts (timing belt, timing belt tensioner, water pump and coolant change), labor and shop supplies before tax. We had it done at that dealership. They picked up the Odyssey from our house, keep us updated of the status and wash/clean the Odyssey before dropping it off. Five hours from door to door and right on time.

Anything parts that we add in between the work is free labor so we paid for the serpentine belt tensioner part since we broke the bolt off the serpentine belt tensioner by pushing it too hard with an extra pipe years ago. Retroactively, we should have paid a little extra to fix the oil pump leak during this second timing belt change.

On another post, I think another person paid $950 or $975 for this service at another dealership. You can always ask and negotiate with the service advisor or counselor to lower quoted price. They have specials during previous months or promotions that they can always leverage.

Good luck

Definitely DO NOT have this done at a dealer. That dealer price is about double what the job should actually cost you.

As I already said, order the Aisin kit from Rock Auto and then have a competent independent mechanic install all those parts. Kit is less than $200; labor to install should be in the $500 - $700 range.

Local shop should be able to do it, but just ask them. Some places are more experienced in Hondas and some less. My local place charges $95 per hour for labor and quoted me $450 labor only.

Since my two boys and I did the work, I "paid myself" $150, then paid each of them $150 for their help.

Good decision. I don't know how your mechanic can quote $357 for the Aisin kit.

It retails for $180 at Rock Auto. Buy it there. Do not buy it from Amazon orEbay - lot's of counterfeit kits sold there.

You want Aisin kit # TKH002



I recommend you also buy the following and have it all done at the same time:

Buy a new thermostat (Aisin or Honda)
Get 2 gallons of Honda coolant
Buy new spark plugs (NTK Iridium)
Buy a new serpentine belt (Genuine Honda)

If you get the Aisin thermostat you may have to buy the seal separately. The Honda thermosat comes with a new seal.

Depends on the mechanic, some will, others won't.

Ask your mechanic where he is seeing the Aisin kit for $357. That’s outrageous.

Even at NAPA it’s $272, which is the highest price I’ve ever seen for it. Do a google search and you’ll see it for around $180 -200 at most places.

I am looking at getting the Aisin kit from RockAuto online and it is $180. I am going back to him to quote the additional items to be done. Let me see if I get negotiate with him a little bit on the price to have it under warranty, his labor cost seems reasonable to me and I have already change the passenger axle seal with him and he seems to have done a good job on that.

Just wondering if anyone can recommend a reputable local independent mechanic in the CT area to do the timing belt/water pump/tensioner/etc service. My 2005 Odyssey has 177,000 miles. The timing belt/water pump was last changed in 2013 at ~90k miles at a Honda dealer. I think the cost at that time was around 1100.00. Thanks.
 
#32 ·
I do not have a CT mechanic recommendation, but I do recommend you order the Aisin timing belt kit from Rock Auto for $180 and when you find a good local mechanic have him/her install it for you.

I don't recommend this but I got my timing belt done for the 1st time at 165k. 3rd owner. 1st 25k in NY, next 50k in Miami area, last 90k in central Illinois. My hyd tensioner started clacking in cold startup scenarios, quiet down once warmed up. Drove it for 2-3 weeks in warm weather on vacation & drove home 1000 miles so that I could get the job done outside of dealerships. Old timing belt showed virtually no signs of wear, water pump was in great shape (no leaks, no impeller/bearing issues) , tensioner pulley good (had a worn spot where tensioner was clacking, idler pulley bearing worn a bit & bearing showed signs of wear, serpentine belt chafed & signs of damage, tensioner shot leaking fluid. See ya again at 300k? We'll see, but will keep eye from 275k on.

The problem with fake ebay kits is commonly the belt. The belt fails and KABOOM make it rain $$$ at your favorite local shop. The guy in the video bought his kit from ebay. Read the comments for "that just happened to me too!" from several people.

The big 'if' with timing belt longevity is if the belt is exposed to oil or coolant, both of which will degrade the belt.

Regarding supporting your local and honest mechanic, the issue is he's got to make enough to support himself, his wife and his kids, pay his taxes, pay 16% on Social Security, pay the rent on his shop, pay his health insurance, which can be upwards of $20K, and support callbacks. All of which is why he marks up his parts.

Finally, an honest mechanic will only charge you for the work that actually needs to be done. He will not make work, and by not making work, it makes it hard to be profitable. Go figure!
