DIY: Replacing heater hose pipe T's *important* (1 Viewer)

[Qtonic]

No problem, good luck!

P.S. I highly recommend these:

2 Pc. 16 in. Long Reach Pliers Set - or the longest you can find. The 90 degree is especially helpful.

11 in. 45° Bent Nose Long Reach Pliers - 45 degree is also nice though longer would be better.

Thank you Soooo much! Ordering now... very much appreciated.

Also, if you’re replacing all the hoses simply cut them off near the T’s to prevent the T’s from crumbling while trying to twist off the hoses. Then you can loosen the six hose clamps at the metal fittings and pull the hoses off.

Keep track of which hose is which and assemble the new hoses & T’s on your bench using the old assemblies as a guide. Then transfer the two new assemblies to the truck and install.

Anyone who replaced the 2 hoses (87245-6A090 ) by the transfer case also replace the clamps? With some clamps being wrong on the parts diagrams, were the 96136-42501 clamps correct for this application?

Actually those are incorrect - too big. The rear hoses are identical to the smaller (vertical orientation) hoses that connect to the tees. I just verified since I have the parts for the rear but have not installed yet. So I would use 90467-19022.

I don't know why these diagrams are so off.

Edit: If anyone sees this and needs some new clamps, I have 8 of the large ones for the horizontal hoses coming off the heater tees. Also one hose 87245-6A201 for 02/99 to 08/02. PM me.

Thanks, I think this is the first wrong part i've ordered from my dealer (for any of my cars, thanks to great forums like this for making it easy for my parts guy). Let's see if they hassle me when I go there to return them and order the 4x 90467-19022.

I paid for this service on my last 100, this time I tackled
It myself. Not bad when swapping the hoses as well. These Heater T’s swapped out at 102k miles and 20 years old in my 99 LX. Showed some signs wear, but was intact when removed. Here’s a couple pictures. Thanks toy all the info, I was able to do this in about 45 min. I also changed my oil while I had the front skid removed. I also figured it wouldn’t hurt to label the hoses to document the service.

OK.. have all new hoses, fluid, clamps, Ts, etc. on hand and just started the job. Then... things LOOK so good I'm wondering if it's necessary now. Should have checked first, I guess.. just assumed that it would never have been done before. Bought the vehicle w/ 135K miles on it last summer, and there's a sticker saying the timing belt service done at 79K. It's got 139K on it now, and I'm doing an oil change now, too.
When I started to drain some coolant, what came out is the pink/red stuff in what looks like very good clear condition. Also, the hoses, clamps, and Ts look pretty new, too, and NO evidence of leaks, corrosion, decay, or even really dirt. Pic is attached. To my eye, it looks like the previous owner (bought from a used card dealer.... carfax was good, but know NOTHING about the PO) took great care of the vehicle, and I'm guessing that maybe the Ts/hoses/coolant may have been done at some point since new? Only issues when I bought it were w/ the Levinson stereo which I've remedied.
We're going to be taking about a 2000 mile trip over the next two weeks. Would you suggest going doing the job today anyway, or do you feel, based on the pic, that we're in good shape and maybe just take the parts just in case?

Hose clamps turned down is a pretty good sign that they are original. You can't really tell what they look like without taking them out. I would go ahead and do the Ts, though I probably wouldn't do the hoses unless you see a sign of a problem.

 

[Balto1223]

I agree with the above comment.

Mine looked decent like yours until I pulled them. Better to be safe than sorry in this situation. Unless you want to be changing them out on the road..

Thanks for the thoughts. Finished. Attached a pic of the Ts I took out. No crumbling... couldn't crush'em by hand no matter how hard I tried, and they came out of the hoses easily. Getting the hoses off the nipples in the car was another story.. had to cut them off. Probably could have just done the Ts in place instead, but was worried due to all the warning about crumbling Ts so I took the hoses out as three hose/T units. My guess is that this was most likely done before since everything was in such great shape, but I don't feel bad about having gone through the process. Now the stuff's even newer, AND I've learned that the last owner really took care of the vehicle. Have also been reminded of several axioms of auto repair...

1. You can have light where you need it, or you can be in a good position for the leverage you need, but you can't have both.
2. The hood WILL fall on you if you forget to prop it up w/ a wooden canoe paddle.
3. No matter how many tools you keep close on hand underneath the car, or while crawling around in the engine bay, the one you need is the one you just left on your parts bench.

All in all, not a bad way to spend the day. Wish I was a LOT taller (5' 7"). I've got one of those "tire step" thingies that helped me get in and out of the engine bay, but even standing on it I couldn't reach what I needed to reach. Everything went well.. thanks for the help.

Do other Toyota vehicles with the 4.7 have the same tees that need replaced? I have a 98 hundy that I'm about to do and I also have an 07 sequoia.

Yes all 4.7L. I now see that even the 5.7L have them.

The first gen Sequoia does have heater T's, the Tundra does not (at least not in my 2000 access cab).

Just stopped at my Toyota to get a price on parts. Service guy was a bit confused so he walked me to the garage where one of the mechanics was working on a '00 and had the manifold off working on the starter. I pointed out the 6 hoses and 2 tee's and the technician said, "oh man, I have no idea how you'd get to those with the manifold on, I'd have to pull it to get to those." Told me if they did the job it would be $900 in labor. I just and told them to print me out the parts which came to $293 for the 6 hoses and 2 tees. Time to shop around online.

Wow, i'll take find another dealer for $100 Alex... ....compiling the list of part numbers for the hoses is on my to-do list as well, might you be willing to share that list?

Just did mine last weekend ('02 LX just purchased). Not sure if they were done before but clamps were facing down so assumed not, amazing if that's the case at 269k miles.

Here are the part numbers I used (Camelback Toyota)

87248-60460

87245-6A180
87245-6A210
87245-6A190
87245-6A220
87245-6A201

Thank you for the info.. I will try to find my production date for my 99 LC and than match the part numbers to it

The T's are for the 2nd row heater. Some rare, US 100's did not have 2nd row heat and therefore no T's.

I assumed so, thank you for clarifying.

Thanks for the list, these match for my '06, did you replace the clamps at the time as well?
