Considering buying a complete rubber hose kit for my 2015...

My Tacoma has only about 90K miles, but I am thinking of purchasing all of the rubber hoses (Coolant, brake, etc.) to store in case Toyota stops manufacturing these hoses. I think that as long as I keep them sealed or coated with silicone, they should last more or less forever until I need them. I figure around 250K miles I'll just go through and replace every hose or line whether they show wear or not.
Is this something I should be worried about, or am I overthinking it?

 

I like this general line of thinking (stockpiling parts for the long term) -- idk the specifics of rubber-hose shelf life, nor how long a specific set of hoses generally remains easily available from Toyota.

The only thing that stops me from accumulating a huge inventory of original Toyota spare parts for my 2nd gen is the possibility that at some point my vehicle gets totalled by somebody on the road. In that case (if I didn't get another identical used replacement 2nd gen) I could just sell them piece by piece on eBay but that would be a lot of time and work.

Currently all I maintain a big stock of are original Toyota oil filters & engine air filters.

 

I’ve got some front brake lines ready to go when i need them.

 

I guess a sensible first step would be to go over the 1st Gen forum and ask if anyone there has any trouble finding hoses for their vehicles yet. If they aren't having any troubles yet then I'd suspect you are good for at least another decade before needing to worry...

 

Why

 

This ^^^^^!!!! X10 and YES you’re way overthinking it.

 

I think you are over thinking it.
Unless you just want OEM?
But aftermarket hose have been pretty good for me.
And I think the aftermarket will be around for a long...long...time

 

why don't you figure out

-Toyota's policy on NLA
-when they do that, if at all (Mercedes for example used to never do that. Audi does.)
-aftermarket
-dry rot in storage
-what you own owns you, you have to carry and keep that shit
-replace things when they need to, or preventatively
-realize Toyota plastics and rubbers get formulated better than other brands, and subjected to less harsh operating conditions
-figure out who the actual suppliers are, how long they supply parts

The latest year was 2015. That is not old.
The latest year of the motor (1GR), probably 2023 in the 4runner.

1st gen is still around. Pickups are still around.
This is a mass produced vehicle, by a mass produce company

not a niche vehicle
when the time comes, whenever that may be, there will be a stock. In warehouses. You will not have competition from the average person who
a. neglects their vehicle
b. has moved onto something else worse and can't handle diagnosing their simple issue, let alone a repair. $20 will be $1000 paying someone else to do it, then they will warp their mind to say "well it's old and done for, this is too expensive, therefore I have to get something else worse"

I would be more concerned with things like an engine harness drying. Don't know about Toyota. I know Audi has a beefed up one for like $100 that goes right on.
Not an $8 hose that folks are still running with 200-300k mi.

in 10 years, whatever it is, you'll probably be able to get it
and that's if you haven't LS-swapped it by then
Look at 110 era 90's LR Defenders. They drive in the US, even though they were never really sold here.

 

Meh, you can get coolant hoses anywhere, doesn't have to be OEM. There's so many 2nd gens on the road, these aftermarket companies will be making stuff like that for a long time

 

I just used some bulk buy hose for my PCV Valve hose. My dad had a length of it in the garage so I cut a piece to size. Before that I bought a length of hose at the auto zone when I replaced my broken trans oil cooler hose. I took the old hose in to match the diameter.

Also I used

$15 AT-205 Re-Seal Stops Leaks, 8 Ounce Bottle

AT-205 to try to keep my older hoses and other rubber good. I put it in a spray bottle, spray it on a rag and wipe things down.

I've done this once but it's something I think I'll do it again this summer.

I'm just trying to do everything I can to keep my truck going. Maybe it's worth it, maybe not, but it makes me feel like I'm making a difference. Good Luck!

 

I like the idea of a kit for coolant and heater hoses, but from my experience performing first articles on coolant hoses, as long as they're OEM, Gates, Dayco, or another name-brand they're fine. The material compositions of vehicle coolant hoses have improved tremendously since I started driving. I never had to do destructive tests, just verified that the part number and material spec code were on the hose, the material cert was with the sample, and the dimensions were close enough for fitment.
Like fan or serpentine belts, if you purchase the less expensive one, you're asking for trouble.

 

Throughout the years, I've found OEM parts support is excellent from Toyota, especially on drivetrain parts. 25+ years later, interior parts for our '87 4Runner were getting harder to find, but OEM drivetrain parts were always available and often in my local dealer's inventory. And quality belts and hoses are always available at parts houses.

But COVID and the resulting supply chain issues that followed definitely changed my thinking on this. I've found I've started collecting/amassing more consumables, especially after my 2 preferred oil brands had been sold out at Wally World for nearly a month. Man, that was a weird time.

 

I have a full set of idler pulleys still in the box, but I think the aftermarket support for things like hoses, is pretty good. I might keep a spare water pump or something like that, but hoses are just too easy to find, quickly, in my opinion.
