I ordered during a sale. It was quite a bit, but, if they last another 280,000 miles and 23 years, worth it.

Oh, and carefully cut and peel the old hoses. The fittings to the core are soft aluminum. Also, the clamp on the passenger side to the pipe that goes into the valley, yeah that clamp if not affixed will slide right on down under the plenum. Took patience and two flexible retrievers.
I decided to stick with the OEM T’s. The replacement will just fall into my 90,000 mile timing belt replacement schedule. On my 06 I only replaced the T’s (they made it 250,000 miles). My 02 T’s had been replaced with a gates and a factory T but several of the clamps were worm type and digging into the hoses and I wanted to go back to factory compression. So I went ahead and did the hoses at the same time. I do not care for laying up in that engine bay.

Personally, I only replace the first hose in most cases. The hot (driver side) 90 elbow hose. Unless heater hoses, are swollen. Swollen, as seen near clamps (puffy look down stream side of clamp) indicates overheating, which is hard on the rubber hose. Those hoses, are trash. The typical hose in well care for engine, are fine. Even at 25 year and 400K mile, that I've seen.
I replace the 90 degree elbow, because. Removing plastic Tee from engine side of hose, they'll often crumble. Which result in plastic dropping into engine side 7 out of 10 times. I can blow out heater cores, but not the engine side. So plastic ends up, in coolant system. Sometime behind thermostat, which I can get to. But sometimes, gets into oil cooler. Which I can't get to, without removing oil cooler (PITA).
When removing that 90 degree hose, I cut it off. Using a hook razor blade. I'm very careful, to not score the metal pipe coming up from engine (rear water bypass), as I cut the hose off it. I'm just as careful, to not put any lateral pressure on that pipe. That pipe is pressed into rear water bypass. Too much side to side pressure on pipe. The fitting where pipe pressed in, will leak. Then, rear water bypass, must be R&R.
Toyota recommends soapy (dish soap) water ( I use Dawn). Which, helps slip hoses on. It also aids in, rubber hose light attaching (fusing) to metal pipe.
Tip:
Place clamps, back into the impression they made on old hose and same orientation. Which is a Toyota how recommends Which helps, reduce chance of leaks.
With new hoses we place clamps in any ortation we like.

At 12 x 15 x 15mm those are a little undersized. They should be 14 x 17 x 17mm.
Excellent, I'll start with the Ts and the 90 hose. Maybe that's why RockAuto only carries those two items. Thank You!
great point on the fragments. On my 06 I clamped the hoses on all sides of the T's. While fruitful, it was nerve wrecking (and I mean wrecking) positioning clamps in spots where I felt they would not damage the metal inlet or outlets, or cause one of the T's to crumble. So I worked my way up. Bottom of the T first, then the engine sides and then with some special clamps that I had from years past to work on fuel hoses on my Mercedes W210's that are crazy compact and thin, the core side. This made maneuvering even worse. So when it was time to do the 02, I just dumped the hoses. That seatbelt type cutter / hooked blade is another awesome tip!

Nice find! Ordered bunch of brake fluid. Thank You!
Checked my Ts and it looks like one of the previous owners already replaced them. Here are some photos. Maybe someone can chime in?
I mean at the expense of $30 and a half hour you’ll know they are good for another 90kmiles. I don’t think external visual is the best indicator of remaining life and I wouldn’t pull apart the hoses without have a spare set of tees on hand. 8724860460

Likely, they've been changed at least once because the original orientation of the clamps is 180 degrees of what you have it at.
Already ordered a set and a 90 hose from RockAuto.
That was my initial thought as well. I t seems like the second previous was an enthusiast and took care of the truck.Likely, they've been changed at least once because the original orientation of the clamps is 180 degrees of what you have it at.
Received my Ts and hose from RockAuto. Ts are made by Autotecnica from very high quality and sturdy plastic. They also comes with the Lifetime warranty. Hose will need to be cut to size but feels really good too. Will throw them in glove compartment for now just in case.
Just replaced my heater Ts and I'm glad I did because it didn't take much force to snap the base off one of the Ts; I did have to slice the hoses to the firewall but the others just twisted off.
I used the following part numbers.
96134-42100 x 8
90467-19022 x 4
87248-60460 x 2
87245-6A210 x 1
87245-6A220 x 1
87245-6A800 x 1
87245-6A190 x 1
99556-20155 x 1
87245-6A180 x 1
I also ordered 4x 96136-52101 in accordance with the parts diagram (schematic 2/3) but they're too small for the firewall pipes and I didn't bother fitting them to the rear heater supply/return and used 90467-19022 instead.
I didn't bother sourcing the brass Ts as these plastic ones lasted 21 years.

For peace of mind, my rule is to always replace the heater Ts at every timing belt interval and the heater hoses at every other timing belt interval.
