DIY: Replacing heater hose pipe T's *important* (2 Viewers)

[gregnash]

So I found that Stan @NLXTACY has a kit on his website so picked up the kit and currently waiting for the engine to cool down. Don't know if all y'all have some old farmer vise grip hands or something but DAMN are the clamps that come with the kit SERIOUSLY tight!!! Luckily I was smart enough to start putting everything together prior to trying to take the hoses off the truck and struggling there. Now I should be able to get them on semi easily all in one piece!

If you’re also replacing the hoses just cut the old hoses and don’t risk the T’s crumbling during disassembly. Get those cable clamp pliers for the clamps, you won’t regret it and they’re useful on a ton of other clamps as well.

Yeah ended up replacing everything with the kit. Looks like the upper hoses (larger) are a slightly larger clamp and the lower hoses (smaller) are a slight smaller size but the kit has all the same size clamps, the smaller ones. They still work perfectly on the larger hose just tight and a PITA to move into position. I will probably invest in a pair of those pliers seeing as I am sure that there are other hoses that I will have to replace at some point.

Otherwise between a pair of channel locks and a pair of smaller needle nose vise grips I was able to get everything taken care of. Took her for a shakedown run last night and no leaks.

I just finished swapping out all hoses and both T's...one snapped at 268K but at least I was near home, not stranded somewhere. I guess it should go without saying that if you're doing an LX rather than a LC you should drop the height control to the lowest setting (hey, I'm only 5'8"! ...still needed a step stool!). I also replaced the OEM clamps with the threaded type. In the end, sticking with the OEM-type clamps may have been the best way to go; screw type may need even more careful placement if you're trying to make the "next time" easier (won't be me, so...).

Your best friend.

This tool and Anti-Seize (A/S not to be used on this project) are two things every Cruiser owner should own IMO.

Just replaced mine Saturday.

Went with 100% OEM parts, but just wanted to give others my experience.

Walked into a Lexus dealership (my truck is an lx470) with my part numbers and diagram, got a price quote: $230 for 6 heater pipes and 2 plastic t's - kinda funny because I think they expected me to just pay them for parts and labor and were a little confused when a diagram they pulled up matched exactly what I handed them.

Then drove down the road to the Toyota dealership, and gave them the parts list from the lexus asking for a price quote, they quoted me $160, okay cool! Saved some money! Went back to work (lunch was over)

While I was at work I pulled up that toyota dealership, saw you could order parts online, and priced them out.

$117 tax included, shipped (Next day) to the dealership.

Not bad considering the price went from $230 from Lexus, to $117. the exact same parts, OEM quality, and now I know my heater T's and pipes will be good for another 100k miles at least. (mine were in decent shape (not as bad as I've seen others). My lx470 has 254,000 miles on the ODO, and have no idea when they were last replaced.

overall, a win win, and now I feel much better that the parts are replaced, and clamps are facing a way that makes it easy next time I need to replace the heater t's

Hi all, I recently purchased a 2000 LC from another user on here and want to/need to replace the Heater pipes and Ts. Can someone link the part #s from the 33 pages on this thread for me so I can purchase them?

Also, how difficult is this job? I am somewhat knowledgable with vehicle maintenance (oil, brakes, rotors, power steering, etc. ate things ive done myself) but haven't done anything with heater/radiator/ac before. Is this just un-clamping pipes and replacing them or does this require more serious work?

Thanks!

I’ve attached my parts list from Lexus (which I showed a Toyota dealership parts guy) and he was able to match the parts up from the Toyota side, and then I was able to search the parts online

Now these are parts numbers from my 2006 lx470 that has the VVT motor. There shouldn’t be any differences with the parts number but figured I’d throw it out there.
Also, in terms of how hard this is it’s absolutely not it’s an annoying job to do but not hard. I have about the same level of skill that you mentioned in your list.

few things that I did to make it a little easier I removed the plastic engine cover. Got an old couch pad and laid that on the engine and then laid on the pad while I got to the pipes I also cut my old pipes out.

my clamps were in the stock (downward facing) position so getting a bulk of the pipes out of the way made things a littler easier for myself.

Awesome. Thank you so much! Like I said I bought my LC last week and after the inspection, this was one of the things that came back as something needing to be done. I had a few other things too but I figured I'd start here and go on to the more difficult things.

Update:

While doing some research today looking for parts from your list (LX to LC) I found this website: PartSouq Auto Parts Around the World

It allows you to put in your Vin and find the diagrams for almost any system which then has hot linked part numbers. I was then able to enter those part numbers in on the Toyota part site and make the purchase form there. For my 6 hoses and 2 Ts it was $119 before shipping.

I'll be swapping these out this coming weekend.

Thanks for your help devlooper and everyone else on this thread. This will be my first replacement for my new to me 2000 LC.

That was a pretty good inspection if they caught that! I've seen lots of guys mention they have Toyota Techs miss their heater T's when doing the timing belt and water pump replacement.

Super easy job, just annoying and uncomfortable, but heater T's are a good first base lining. Only tools I used (literally) is a razor blade, and some pliers and 10mm sockets (sockets to remove engine cover)

One thing to be careful of is the fitting that come out of the firewall are press fitted into that sheet metal so dont tug on that too hard. I think someone in this thread yanked the hell out of them and separated them from their press fitted location which caused crazy leaks.

Glad you were able to find all the parts you needed! Enjoy your new rig!

And the shop I had inspect it was a Toyota 4Runner specialist shop but had been recommended to me from another forum that new of them up in Dallas. He was very thorough and did a great job. I'll recommend him to anyone. He said there was a slight smell of coolant when he drove it and suspected the heater hoses/Ts. After researching on here the past few days I decided I'd attempt this repair/replace myself and see how it goes.

• By-Pass Hose — Part # 16261-50090
• Overflow Hose — Part # 90445-12078
• Radiator Hose - Upper — Part # 16571-50150
• Radiator Hose - Lower — Part # 16572-50150
• By-Pass Pipe — Part # 16206-50120
• Return Hose— Part # 15777-50030

Literally linked a few posts above you and multiple times throughout the thread?!
FYI - there is a vendor (Absolute Wits' End) that sells and entire kit with everything needed; T's, Hoses, Clamps, for this job that I referenced a few pages back. Think they are the only ones that do but not 100% on that.

I was able to do on my 98 LC in a few hours and that was mainly waiting for engine to cool down after work and then fighting with needle nose vise grips to get clamps off/on. There is a specific tool linked at the top of this page for this, I would highly suggest purchasing as it will save your hands and lots of cursing!

To replace the heater T system on my '98 LC I purchased Four Seasons 84543 stainless T's and the following six hoses:
87245-6A170
87245-6A180
87245-6A190
87245-6A200
87245-6A210
87245-6A220

If you want OEM T's buy 87248-60460 x2.

I've been ordering from this "Coolant Hoses the Complete List" below.

Though I cannot find part number 87245-20200 hose rear water outlet (from heater unit) x 3 $9.34 ea

Coolant hoses - the complete list

My 01 is still pretty much all original aside from routine maintenance parts. The upper radiator hoses are nearing the end of their life and after spending a couple hours looking for all the required hoses in one list I gave up. I want to replace them all at once along with the thermostat...

Have the green highlighted hoses been mentioned in this thread?

 

[bobcatag2006]

Well I started on my hoses and Ts but have come to a break in the action. I ordered the parts from a shop in California on Tuesday (Paid for expedited shipping *not* overnight) and estimated delivery was tonight (21st).

So, while I was was waiting for them to be delivered I decided I would remove the old hoses and pipes. Easy enough...took about 30 minutes because those were tough to get to the clamps and get them clear to remove the hoses. I did purchase the tool from amazon for the clamps and they helped. Would've been 1hr+ without it just to get them off.

In this picture below you can see I got one pipe off and the T had completely broken off. They crumbled in my hand once I got them off.

All pipes and Ts removed:

"Rebuilt" the parts/assembly so I can remember where they go, all because my shipment got delayed. I get a notification that now the parts will arrive by 8pm on Monday instead of tonight. Good thing I didn't have anything planned for this weekend...oh wait, yes I did. Not taking a trip out to my buddy's land in the new truck anymore. $%^&


Anyway, to be continued after the weekend...

The OEM clamps will not need to be retightened like most screw type clamps. They worked fine on mine with no leaks. Replaced all the heater hoses with OEM parts at the same time. Rear heater included. Should be good for another 14 years.

Late to the party... but what's the business on "rear heater" replacement? More hidden Heater T's need to be done for preventative maintenance in the rear?
