Good call. Thanks for the tip.

Post #12. @anniesball72

Thanks, my bad, I didn't read the full article.

With 225k miles on my 1999 is it recommended to swap the hoses out? My mechanic said nothing needs to be done yet except my UCA is looking like it needs replacing, but he never mentioned hoses and such.
Thanks ahead of time

Of the things that have left me stranded over my years of driving old cars (non-Toyota), coolant leaks are #1. That's been water pump failure and hose failure. After that, it is brake hose failure. Luckily no flats. Keeping good hoses is cheap insurance. Old hoses either get softened and thin with age, which causes bulging, or get hard and brittle. Just inspect them and see if they appear soft/bulging or brittle. Also look for any evidence of mineral deposits/dried coolant at fittings.

Everything on your truck is 20 years old. Age and heat play havoc on rubber... thus anything rubber ought to be suspect. That's all the rubber coolant lines, all the vacuum lines, the bushings, fuel lines, brake lines, even o-rings. That stuff does okay so long as it sees constant use, but there IS a finite life. And keep in mind, most recommendations are to change the coolant hoses out every ~5 years... so if they've never been done, they're 15 years over-due. (I think that's a BS, CYA estimate, but how far up the creek without a paddle are you willing to get yourself when something finally gives?) If you're going to risk it, at LEAST learn about emergency repairs and buy the supplies to keep in the truck full time.

As a FWIW, there is a silicone kit from HRS for $138 that contains the lions share of these hoses used with the heater ~ 57-1798-BLK (they have red and blue too, I'm not into bling). Plus another kit for the main upper and lower hoses... 57-1217-BLK-1, though I found cheaper options. Just leaves the oil cooler and for those that have them, the throttle-body that must come from Toyota.

I saw the HRS kit but adding the rad hoses were more then oem hoses, and since oem lasted 19 years I went oem. Only thing I'm a bit pissed about is I just replaced my radiator (hole in it) and then a month later koyo comes out with a full aluminum radiator...go figure. So when funds permit I'm going all aluminum koyo and the new used rad (also koyo) will go up for sale.

Yes I want to do all of that and replace all hoses and whatever else you think, I’ve been looking at them and they look and feel fine, but I’m no mechanic so I can’t tell but as being 20 years old I feel like none of it was replaced during its lifetime
I got the belt and pump changed but I’d like to do more work on it before it becomes a problem

Any recommendations on where to buy these parts?
Thank you

I would also check/change the transmission cooler lines that run to the radiator. Twice I have had these fail on trucks with over 200,000 miles because no one ever changed them.

Now when I buy an old car/truck I check them right away and the last few old vehicles I bought they were soft and not in good shape. I changed them out on my 4Runner when I put in a new radiator so they should be good to go for years. If these fail they will of course leave you stranded if you lose fluid.

don't forget about the heater valve they get brittle.

thanks so much for this....was getting ready to figure this out for my next timing belt/pump job
thanks

I had completely forgotten about this. Your welcome, glade you got some use out of it.

Challenging for sure since Camelback does not list these hoses by the original PN, for example the hose to right of tee is 87245-35720. Doesnt show up on their part search. Camelback parts guy sent me a diagram, new PN 87245A (and B, and E for the other hoses off heater valve.) Plug that into their search bar and NOPE, doesn't work. Then they gave me a superseded #87245-3D230. Plug that in and it says "won't fit your 97 4runner. What the actual FORK!

i know this is an older thread but i'm currently purchasing all the hoses and clamps to do this same project. there is a clamp that is no longer available, it doesnt look too important. but i was wondering if anybody has had to replace theirs with something else? mine seems fragile and i'd like to replace it without getting another old one from a salvage yard.

Do you have a photo or part number of the clamp you’re asking about?
