Use the #10 clamps on the tee side. You can reuse the factory clamps on the engine/ firewall side.
Decided to do these. Got the 4season t’s and installed them. Started the car and discovered that a lot of the coolant was leaking. Either my hoses are too big (fat) or I need new clamps. Reinstalled the Toyota ones for now as they still in decent condition.

Toyota clamps must be placed back on hose they came off in same position as they were in.
Use worm clamps instead, or orient the oem clamps in the indentation that were before, this gives them that extra compression on the fittings.
The guy doing my timing belt told me that my hose T's were "like mush" and broke apart when he removed them. Had to pull another hose just to fish some of it out. Original T's on a 17 year old LX with 170k mi.
If you haven't done this on your 100, for the love of god, do it. Total parts cost $20.

I'm careful to get every piece. Once each piece on the bench, I pieces together like a puzzle. This time I was missing a piece, which may have fallen out onto transmission. Not sure, where it fell. I back flush, the engine coolant system with a pump. Finding only a small piece in my back flush catch can. Which was not as much, as I was looking for, I just moved on with flushing entire system as planned. After running gallons of distilled water through, I move onto replacement of thermostat.
Ureeka!
00LX 557,550Km had no record, these Tee's had ever been replace. Not as bad as one would think 557K KM. About the same as I find on low milage 04-07. Something to be said for more frequent flushing of the Toyota LL (red)

Did both "T"'s today on my 04 LX at 110396 miles.
took about the time to drink one cold beer.
Inboard "T" was fine, outboard was deteriorating.

You like drinking warm beer?
Some beers are meant to be drank warm (correction, room temp beer).
But I prefer cold beer during the summer...

I've done enough of these to wise up and remove the hoses with the tee still on, esp the hot side. No chance of it breaking and you can easily seat them back in without them leaking.
I think I might have set a new record for heather tee life - the hot side finally went on my '03 after about 270,000. Please don't wait this long, but now you know the upper limit! Luckily the wife was right near the shop and did not drive it long enough to ruin the motor.
It's one of those jobs I had on my list but I could never quite get around to doing it. One problem was finding all the parts numbers for the hoses and tees. The dealers I called couldn't help and I used the diagrams and part numbers off this board to order the stuff "blind" just hoping it would fit. It wasn't a perfect match, but it was close enough. Job was actually fairly easy for a dedicated amateur mechanic using tips from this board. Be sure to use a sharp knife to split the old hoses for easy removal. This avoids damage to the delicate hard lines .
The cruiser has been a superb vehicle and has never given one bit of trouble in the 13 years I have owned it, even with a "third world" type maintenance schedule, 95% done by a "way too busy for that today " owner.

I did mine several months ago and used Gates Powerclamps. They work great, never spilled a drop even when used on the original hoses that were heavily indented from clamps (I've since replaced the hoses as well as you can see in the pic) Just returned from a trip and it handled laboring up the Colorado mountains and the ridiculous temperatures of Las Vegas without issue.
Is the 4season "T" made of aluminum?
Can't seem to find that info in their specs.

Galvanized steel
thanx
These are the T's to get: https://www.amazon.com/gp/product/B000DCNGIS/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
Just did mine and upgraded all the hoses back there with red HPS silicone hoses as well. No more need to worry for the life of the truck.
Great kit, appears that it is no longer available.
