2012 timing belt replacement questions

2096 78
Hi guys,

Hoping for some advice and I'll try to be brief. Planning on replacing the timing belt on a 2012 with 103K miles.

1) I am going to buy the Aisin kit (includes Water Pump, Timing Belt, Tensioner, Pulleys, Seal) from Amazon (because of my Amazon credit card reward points). Some guy said not to buy Amazon parts. I don't understand why not, if it's the same part number as the Aisin website. Have you heard any such mumblings?

2) Should I replace the drive/serpentine belt tensioner? I am going to replace the drive belt, but the cheapest mid-grade tensioner is around $60. Is it something that you guys would replace while you're at it? If so, what brand would you use for belt and tensioner?

Thanks in advance!!!

They sell the parts, but there is no such thing as a Genuine Honda kit. Anything marketing as such is counterfeit. The closest thing there is to a Honda kit is some dealers will sell the individual parts you need all as one bundle, but the price for that will be a lot more than the Aisin kit or the counterfeits, probably closer to $500.
Everything in aisin kit totals $544 on Hondapartsnow.com,..that's steep.

You have to double check Amazon sellers, for example the BANDO belt on Amazon is currently being sold by "JWToolParts" 馃し

I would not buy any major part for my car from Amazon unless directly from the supplier/manufacturer. Sure, I'll buy a filter here and there, maybe a serpentine belt and some accessories, but never anything I had to rely on and could not get to with a wrench and socket for easy replacement.

Dude, the guy in the post you linked to clearly stated he bought a no name branded belt. The kit I am getting has lots of good reviews. I don't think I am taking a big risk here. Do you think that Rock Auto would accept liability for a belt snapping? I'm not on here to start or engage in arguments. Most of the people that replied think my purchase will be safe. I'm more scared of screwing up the install than I am of the belt snapping. I'll let everyone know how the car is riding after 5k miles. I plan to install it on Thursday (because we already had our Thanksgiving) and hopefully finishing on Friday.
NAPA also sells the Aisin kit, just much more expensive.

I think you're fine. Personally I get nervous on this stuff as there are a lot of counterfiets on eBay and Amazon. For that reason I personally only order something like this from a seller that has no relationships with any scammers - like RockAuto, NAPA, dealer, etc.

Most fakes are of the Honda components. I've HEARD (but not seen) cases of Aisin being counterfeited too. With that said "Aisin Store" + Ship and Sold by Amazon makes me a lot more comfortable. The bad news is that if you ever DO get a counterfiet you can be assured it'll destroy your engine just at about the point you think you "should be safe" in that 5k - 15k mile range. Sadly there have been countless stories of it here which is why people are understandably nervous about it.

@Nail Grease Has a picture he posts of what everything should look like when it arrives in an Aisin box. I can confirm that mine looked EXACTLY like his when purchased from Rock Auto.

I鈥檝e bought from the Aisin Store on Amazon and received a genuine Aisin kit.

What people have to recognize is there is a difference between the fake Genuine Honda kits on Amazon and the Aisin kits on Amazon.

This is what the kit that a bunch of people fall for looks like:

Nobody wastes their time marketing as a fake Aisin kit, they go straight for the Genuine Honda brand.

When someone mentions getting fake parts on Amazon, 99% of the time they are talking about kits like the one above, not the Aisin kit.
This statement isn鈥檛 exactly true.
I鈥檝e seen sellers use the Aisin name (minus the TKH-002 part number in the description) by having an Aisin water pump in among their junk parts (minus the TKH-002 part number in the description). They often entice buyers to their kits by adding a serpentine belt and/or cam and crank seals. I鈥檝e also seen sellers use the TKH-002 part number to sell their junk kit (minus the Aisin name).

Personally, I鈥檇 spend the extra money for something that鈥檚 done once every 7 years or 105k miles.

You could.
I鈥檝e been buying Aisin timing belt water pump kits for years, for various makes. I鈥檝e never had a failure. They contain OEM supplier parts. I鈥檓 confident in what I鈥檓 buying.

Do you have the tensioner rattle when start on a cold morning?
Nope. It's actually my wife's car. All that has happened is that the alternator died last week and a couple years ago and automatic transmission sensor went bad (and I replaced it with an Amazon part 馃榿 ) Other than those two things, it runs like a top

Do you know if your "Valve Assembly, Spool Front" is leaking onto alternator?

it is often called the "vtec spool valve" on Piloteers,odyclub, mdxers, driveaccord etc.

While counterfeits exist, it's also possible the parts were installed incorrectly.
Just do your due diligence and buy from a verified Aisin seller on Amazon. Do a thorough inspection of the parts and realize the risk is always there. I have bought parts that failed from Rockauto, Napa, Autozone, etc. Sometimes stuff happens.

You certainly could. I went with OEM parts on my Odyssey when I had the belt done on it. Wasn't cheap but it has been a ridiculously reliable car (I really can't say it enough. It has never left me stranded or had any major problems that affected drivability. I've always been able to count on it to start right up) so I'd say it earned it.

VTEC spool valve leaking onto alternator?
It's not really right to call it the VTEC spool valve. Has nothing to do with VTEC. It operates on a principle very similar to VTEC, but it's not for VTEC. This engine doesn't even have VTEC to begin with.

I personally wouldn't think they sell fake AISIN kits on Amazon (as in a full-on fake TKH-02). I buy from RockAuto simply because it's usually cheaper and faster. As a matter of fact, each time I need anything I check RockAuto, then Amazon, a couple of other online retailers and then a local Honda dealer with whom I have a 20% discount on parts. Then pick the best cost/quality combination (fot he exact same Honda P/N or aftermarket kit of choice P/N).

For serpentine belt tensioner - unless it's wobbly and/or noisy - there's no need to change it. Honda shop manual (posted here on this site) describes a pass/fail inspection procedure on it. If you need to replace it - you can go with one made by INA - it's, basically, what HONDA sells as theirs, just repackaging it in their box.

One thing I personally had a problem with was a non-Honda serpentine belt, believe it or not, it felt like it was a tad shorter and was a beach to install. So, I just get an OEM Honda serpentine belt since then and no issues at all.

One less thing to worry about in the future and I hate working on the same area more than necessary, if say the tensioner should fail in the near future.
That's not a good advice. Replace parts when they need to be replaced, no need for "advance" replacement. You're wasting money and filling up the landfills with perfectly good parts. It's not like a water pump that you once again need to take half the car apart to get to. You can replace that tensioner out in the field with a 13mm, 17mm and 19mm socket (going by memory) and a "gearwrench" for bleeding to make it even easier.

You go by the "what's the risk". Serpentine belt will never fail unexpectedly. Before it fails to the point you need to do anything about it, it will drive you nuts by squealing and shaking and the battery charging being wonky.

I just replaced mine with the last timing belt and only because it was becoming marginally noisier, but even more so because last time I replaced the alternator and serpentine belt, I stripped that 19mm stud that you use for bleeding. That was before I bought the proper wrench for it.... The vehicle was 11 years old and had 200K miles on it at the time of replacement.

Nope, I had either a DAYCO or a Continental. Bando kinda sounds like a child of Bondo and Brawndo :)
But I'm guessing it fits well? I get mine for not much more than what I paid for an aftermarket, it's a Honda OEM made by Mitsuboshi.
Bando is my go to now.
I鈥檝e seen Honda parts website give Bando for an OEM.
