Hi,

I searched but failed to find a previous discussion of this:

Is there enough goo in the tire-repair kit for more than one repair? Or does Honda think I'm going to buy a new one after every flat?

Also, are there TPMS sensors inside the tires for the tire-repair goo to coat and ruin?

There are no TPMS sensors in modern Hondas, they rely on a comparison of wheels speeds. (Be prepared to reset them when your tires are rotated.) So, no worries THERE.

Our European car that came with a pump and a can of goo (and no spare) recommends new goo every 5 years. I guess it needs to be 'fresh'. I'd replace afterwards...

I remember reading on this forum that the CRV (or only hybrid?) uses a roundabout method, not based on direct measuring of the tire pressure.

I haven't had great experience with the goo in the past, so for Blanda I bought a donut instead.

My hybrid doesn't supply separate goo; the pump has goo built in, but I don't know how much--i.e. if there's enough for more than one repair--or if what's used can be replenished. There's no obvous refill port.

What you have is an integrated unit, rather than a base unit with an inflator/goo cartridge. Fairly normal to be honest.

I believe it is use once, and then replace. Which adds further cost to a tire puncture for the owner. Then again.. many owners will go the full life of a vehicle, have a puncture here and there, but never actually need to repair/inflate the tire while on the road. Depends on the nature of the puncture.

And of course, a side wall puncture or cut.... don't even bother with the inflator as it will likely fail to seal the damage, and the tire is not repairable and needs to be replaced.

I don't know that a replacement inflator costs, but I am positive that Honda has done the cost benefit analysis for both Honda and owners and made a cost effective choice... even if it does represent some incremental cost.

According to page 6 of this manual (and page 633 of the owners manual), it sounds like the goo cartridge can be replaced.

...and that it DOES expire after a period of time.

Yeah... to be expected for any chemical compound.

Many owners never even check the tire pressure on their spare tires, and when they need to use them.. they find them severely under inflated ... so I have little confidence they will check expiration dates on the inflator and update it with fresh goo.

In coming years this will probably become a pet peeve in the forum.... "I had a flat, and I went to use my inflator kit and the goo won't flow!.... @#$% Honda!!!!"

Good news though is Honda is always conservative with how they spec things.. so if it is rated for 5 years of life, it probably will last at least 7-8 years.

A good instruction guide.. but I see nothing about the actual goo as a replaceable cartridge, or replacement kit.

The inflator kit sells on line for $120, though I see some on Ebay for ~$60, and I see NO listing for any replacement goo cartridge at all. 2017-2021 Honda Pump Assembly, Tire (Repair Kit) 38160-TZ5-A01 | OEM Parts

It says "See a dealer for a replacement sealant bottle and proper disposal of an empty bottle."
Agree that it doesn't list a part number for the goo. I always carry a plug kit, and the pump will still work with or without goo, so I'm not concerned.

So if we were to replace the tires with runflats, would the wheel speed sensors detect a low tire?

I see it now... thanks... hehe.. in the "fine print"

Thing is.. I bet that this may be an error in the documentation. We have seen them before in the owner documentation.. and it could be a change was made to the inflator kit at some point and the change did not get rolled back into the documentation.

I can find no signs of replacement sealant for Honda inflator kits in any OEM parts source.

Looking at other replacement sealants.. some are inexpensive some are kind of expensive.. so my guess is Honda actually will tell you that you need to buy a new inflator kit. But I will keep searching the internet.. because I'm curious what the deal is here.

I see bottles of Slime in every Walmart, but I've never looked at the prices. I usually just get the $5 plug kits, and never had an issue. Just having a system that tells you a tire is low is the big thing. Ideally, it will give you enough warning to get it repaired before there's a problem.

A good instruction guide.. but I see nothing about the actual goo as a replaceable cartridge.

On closer inspection, there is a cover on the back of the TRK that slides up and off, and beneath the cover is a container of goo (see photo, below). The container is removable, and the tire-fill hose slips off once a simple tab is pried upward. The container is 450ml, so depending on how much is pumped out during a repair, it might be good for more than one use. According to the container's label, it is supplied by ITW Global Tire Repair, Inc., 126 Venture Drive, Suite 210, San Luis Obispo, CA, 93401, toll free (888) 457 - 5463, or (805) 489-0490; fax is (805) 489-1920. . I called them--no response (COVID-19)--but their email is [email protected]. According to the label on the TRK itself, the Honda part # is 42770-TZ5-A010-M1, which I assume is the complete TRK. There's also a separate ITW part # --150244, which I'm assuming is the goo container. I have emailed ITW to see if the goo container can be purchased separately, and I will post here when/if I hear back. I see that sjw91 has noted fine print that says a replacement container can be had from Honda.

 

[williamsji]

So if we were to replace the tires with runflats, would the wheel speed sensors detect a low tire?

Depends. If a runflat running without air rotates at a different speed.. it will eventually pop the TPMS alert.

I don't know enough about runflats though to know for sure.

Good info.

I looked up 42774-TZ5-A01 - Genuine Honda Repair Kit, Tire and it is a complete inflator kit.. an alternate it appears to the one we see in the 2020/21 CRVs. 42774-TZ5-A01 - Genuine Honda Repair Kit, Tire

The ITW page for their sealant units is here. Which can looks like the one in the tire inflator kit? Update: none of them, from my observation.. so the bottle you show from your inflator is probably meant only for the single unit repair/inflator units.

And this ITW product looks like the inflator kit used in the 2020/21 CRVs, and it does specify a 450ml sealant bottle.

See post 22 for update information and solution to the "wheres the replacement sealant" mystery.

I've had cars with them, but they all had the pressure sensors in the wheels. Since the sidewall is supposed to maintain its shape when deflated, I don't know if it would rotate at a different speed. Until 50 miles later, when it collapses. So much for my long-term plan....

Good info. except.. I don't see the photo. Photo please?

Yup. Forgot to post the pic. It's there now. Good info on the ITW site. I never thought to look there (Doh!).

The Honda kit does not use Slime though. But I am not sure what sealant it uses.

By the way.... Slime.. according to Consumer Reports is an inferior sealant for vehicle tires... as it tends to harden and degrade. CR also states that their findings are that inflator kits, that include repair sealant, are superior to the off the shelf tire sealants in a can.

Sorry, I should have said more at the time. I didn't intend to imply it was the same. I just meant that it would be an option, after the OEM sealant is expended. The inflator would still work as an air pump.
