What other hoses should I replace?

[Brian.]

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

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.:lever:

Okay, there are a few vin splits, so this is your responsibility to double check to make sure they fit your 4runner.

Since my vin is above 200008 I used 200008 and up part #'s.

Once again double check your vin split with hose part numbers, they have up to 4 different hoses, it's not my responsibility if you order the wrong part #'s.

My 4runner is a 2000 4wd SR5 V-6 w/rear heater.

Perfectly fine to run 100% water UNLESS YOU ARE IN FREEZING WEATHER!!!!!!!!!!! Antifreeze is exactly that, prevents the coolant from freezing (along with some rust preventative), does ZERO to help cool the engine, its actually bad to run to high of a concentrate of coolant vs water. I ran 100% distilled water and rad flush for 3 weeks in my 4runner. I also only run distilled water in my miata with water wetter. My 4runner is running 50/50 and water wetter as it will see winter weather.

Look at corresponding pics to match up the hose locations.

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!

87124-35010 clamp

I recently replaced all the coolant hoses. For a 19+ year old car it's probably a good idea to do it. They will most likely spring a leak at the worst time possible in the most horrid location. The ones that fought with me the most were the oil cooler hoses. The heater core and rear heater were a piece of cake. I highly recommend getting a set of long needle nose pliers. To do all the hoses OEM toyota, was somewhere around $205 for all oem hoses. Since oem lasted 19+ years I went with oem.

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?

yea, 87124-35010 it looks like it just hold 2 hoses together

Does anyone have an equivalent part number for 87124A (rear heater hose plastic clip) which I broke and have zip tied. Toyota says 87124-35010 is discontinued but the volume of zip ties accumulating under the hood is starting to bother me. I found 87124-42030 but it looks like it's for 2 hoses the same size, but this clip has one large one small hose I think.

yea i've been looking for that too. everywhere i look it says no longer available, its probably not necessary, but i'm trying to stay really stock looking. if i get desparate i'll go to a salvage yard. if you find it let me know! if i find it i'll post the source.

 

[2TH4IST]

Basically any clip or part that is discontinued, check either ebay (I've bought parts from the UAE before with good luck), or hit up the junk yards.

Thanks, will do same. The extreme temps rated ziptie works fine because it goes over the rubber hose protector thing, but I hate having so much stuff zip tied in there. I would get one from a salvage yard but at this age the engine compartment plastic parts are so brittle they break very easily. The plastic wire harness between the valve covers is the worst, just disintegrates on everyone's first valve cover gasket job. I broke the cruise control cable clip above the MAF too but you can still order those as far as I can tell. Part # for that one is 82711-35490.

I dunno maybe plastic clips from a different climate hold up better, I'll keep a look out at the yard anyway.

This thread has a wealth of information in it, replying so I can find my way back LOL

I'd suggest also inspecting the hard lines that go under the passenger side to the rear heater and inspect under that silver shield where they end up for corrosion/damage. If those fail you can lose your coolant.
