Yes Sir, it is correct for your vehicle and mine.
That would be the water bypass hose at the throttle body.
Sorry I've run out of time this morning. I need to get a knuckle on ASAP. Hope you've sorted out parts and other questions. If not hit me in a PM, I'll get to in the morning.
You can also ask your local parts guy at Toyota/lexus dealership, if in doubt.
I use PQ for part ID'ing and numbers, which it's very import to use VIN# .
I enter my VIN into PartSouq. Once I have entered that, I have been looking in the sections for Engine Oil Cooler (1503), Radiator and Water Outlet (1603), and Fuel Injection System (2211) to find these hoses.Sorry I've run out of time this morning.

Ah! So 15777-50030 connects to the other side of the oil cooler!
Then what does the other end of 15777-50030 connect to?
Does it run behind the AC compressor?
Yes Sir, it is correct for your vehicle and mine.

15777-50030 HOSE, OIL COOLER coming from block connecting into backside of oil cooler. Difficult to get to, best done with FDS out/off or oil filter housing off.
16281-50040 HOSE, WATER BY-PASS, NO.5 front/out lower hose on coming off oil cooler to metal pipe
16281-50030 HOSE, WATER BY-PASS, NO.4 short piece going to water inlet housing from metal pipe

This looks like a very difficult hose to replace while the AC compressor is on the block and the engine is in the vehicle...
Not sure I want to take this on right now.
I either R&R water house from block; when DS FDS out which gives more room to reach in, or oil filter housing off. I've never seen it leak, unless disturbed. So best to just leave it alone!
Getting that dipstick tube bolt started during reinstall is a major PIA for folks with big hands, though. I had cortisol oozing out of my pores each of the 3-4 times I had to remove and reinstall that bolt. Perhaps it was my fear of possibly stripping the threads in the side of the head, because I knew that retapping the hole would be even more of a PIA.Supper easy fix. Just clean, remove bolt (reach through fender well), pull tube out, replace O-ring 96721-19010

It's relatively easy if you have long arms!Certainly no need to fiddle with the A/C compressor - the clamps and hose are accessible with the compressor installed. I did what @flintknapper said and just cut the old one off, then reached up from underneath the truck to pop the new one on. Some soapy water and a pair of long needle nose pliers with a 45* bend made installing the upper (block end) clamp a breeze.
