DIY: Replacing heater hose pipe T's *important* (8 Viewers)

I recently did this to my 2001 and reused all my original clips - they had great tension and were more than fine. Two of them were the smaller size (down side of the tee).

Be sure to orient clips where they can be easily reached should you need to remove again.

I've read all 34 pages.

I've ordered all OEM parts:
6 hoses
12 clips
2 "T" pieces

I'm now second-guessing my clips.


Are the 96136-52101 clips useless? @hiteckredneck @flintknapper Should I have ordered 8 of the 96134-42100 ???

Are we confirming that 96136-52101 is an unnecessary/un-useable clip in this situation going forward?

I think you can get away with using all one clip, and I don't remember the 3rd type when I did mine, but I know for sure that I had at least 2 different sizes of clips when I did mine and it all went fine.
 
tried the advanced auto parts Tees that showed up in my search. Stated they were compatible with LX470.

Put them on and was it ever loose. Tightened the screw clamps down and boy did it leak. WORTHLESS. stay away from these.

I think all the 84543 ones will not work as they are smaller than OEMs. Either get new hoses+tees from toyota, or get the 3/4,3/4,5/8 metal tees.

Just stay OEM and replace hoses and “T” pieces.

There just isnt much money to be saved here. OEM parts last 100k miles easy. That’s good enough.

My opinion.

No need to replace the hoses if they pass inspection. Just follow the 20/20/20 rule - $20 for the Ts, 20 minutes to replace them, good for 20 years. Actually they're probably good for only about 15 years, but 20/20/20 is catchier. It is fun to watch the rampant, unchecked OCD behavior on a thread like this.

I got pissed at the aftermarket T's.... The metal ones were the same price as OEMs but I'm sure the metal ones won't ever break if they would fit. So I went to Toyota dealership and they had a couple of the OEM Ts. Soon as I asked for T's they already knew it was for a Land Cruiser. Ha.

Stayed with the old hoses and it fit just fine. I don't think the hoses are under extreme pressure/temp so the hoses i'm sure are over designed. Will start cracking before they fail. Besides, it's a $35 fix for Ts or a $125 fix for the hoses.
 
Hoses are “built on the bench”

Just ordered for my "new" 100. Can't wait to get this off the back burner.

$84.50 shipped from partsouq
 
Have had the tees in my parts bin for well over a year.

151K miles, 2002 - so almost 18 years old, not sure when it was last done, but they weren't super crumbly. A Lexus dealer did the 90K service in 2011, maybe PO had it done at that time?. I did have to fish out a couple little pieces on the hot side, and used a shop vac for extra insurance.

I used hose clamp pliers, but needle vise grips ended up being better for me. Hoses look good, but I really wish I had bought them too. Now having done the job, I really like the idea of cutting off the old, not risk any pieces falling into the system, and assembling the parts at the dining room table in air conditioning.

Lisle spill-free radiator funnel was also nice for topping off coolant.

Spent 2 hours before our church service this morning removing old hoses and “T” pieces.

“T” connectors don't appear to be in bad shape at all. I have 130k on my ‘06LX. Maybe bc they have been changed before OR more likely that the heat isn't used much in the South.

Once I replace new hoses and “T” pieces.... what is the process to replenish coolant lost?

just run engine with heater on and top up overflow/burp reservoir? Or do I actually need to fill radiator?
 
Got this essential Preventative Maintenance item off my list today. No leaks. Coolant level good. Engine temp holding.

Thank yall so much for the community and support.

Top radiator first, than res. Do this with front end higher than rear end of vehicle, is best. Warm up engine with HVAC heaters set to max heat. Check under radiator cap after 8 hour cool down. Check is best done in mornings, before OAT comes up.
 
Just replaced, took about an hr for both just hard to get to. Glad I did one broke off pretty nicely when removed, fished out some of the pieces from the hose
