The Notorious 90 Degree hose
- Thread starter 7EMPIRE
- Start date
Doesn't matter... the hose is the same on both ends. Just measured one of my new spares, both ends have a 16mm inner diameter.

It's really more the geometry of the two ends that matters. If you can match the offset of the two outlets, the radius of the curve doesn't even matter.

i used a hose that was tight on the larger side but i had to over tighten the smaller end. it was so tight that is distorted the hose quite a bit.
does the oem hose tapper?

Oops, thought it was 3/4" =X 5/8" it is, off to find more silicone hose...
edit: Found my old hose in the garage. Legs measure ~2.5", so this silicone hose should work: http://cgi.ebay.com/16mm-5-8-SILICO...arts_Vehicles_CarParts_SM&hash=item45f27c0cef
5/8" hose, 4" legs (have to trim some off to fit). Rated to 428F and 102 psi. For future reference, in case the ebay link expires, it's a 5/8" 90 degree silicone hose made by DPH Sport (DerbyPerformanceHose).
Rummaging for my heat shield still...

::shrug:: I changed that hose once on my car when I rebuilt the engine. The replacement was still fine when the car left me. Two hoses in 22 years and both were OEM. Make sure the heat shield isn't missing...
Anyone got a picture of that heat shield? We're talking something other than the turbo heatshield, correct?
Yes. It's the piece of sheet metal that's part of the hard line:

Shields the hose from the exhaust manifold, something Toyota no doubt discovered during testing. Most cars I've seen have them busted off...

I have read silicone is more prone to blowing off because it doesn't bond to the metal over time like the oem rubber hose would (think about when you remove an old hose and you have to "break it loose" before it slides off)
My two silicone hoses have been on for over a year & still look & feel new.
If the hose is the correct size (16mm ID) & fastened with new clamps it will hold just as well, if not better, than the factory item.
Because of the 90 degree shape its very unlikely to come loose, compared to a straight one, refer to comments about how hard they are to remove.

Sorry jj, I'm lost, I don't see it. What part # is it in the diagram?:1zhelp:
I'm sure its something I will have to order from toyota.

16268 see the little flap of sheetmetal on the left end of it?
Most times that's been broken off so the 90 hose cooks.
What about using braided stainless or braided nylon lines with -AN fittings? Maybe more expensive, but they'll never blow off lol
true, but you'd have to weld on some fittings. I'm not sure if it'd be long enough to incorporate a section of ss long enough to make the turn, and a hard line wouldn't work too well, as stated previously.
...would be pretty sweet though.

Is pnc 16282 in the pic the rear common hose? i suspect mine is leaking and i ordered it today. I believe it is dripping down om my bellhousing from that hose and sipping coolant from my resivor daily. no oil in coolant and no coolnat in my oil and i had some pink residue on the upper side of my head by that hose as it turns to go around the back of the head. also anyone ever had leaks from 16268g? cause i noticed some coolant on the center of the bellhouse too. any help guys this is driving me crazy as i keep thinking ive got bhg and this is my driver for now cause i wrecked my camry. also ive done a coolant drain and fill with the funnel that lets the system bleed out air, t -stat and rad cap. any thoughts?

I replaced both the front and rear 90 deg hoses over the weekend with OEM hoses and clamps sourced from Champion. Using a little soapy water, the hoses slipped on fairly easily. Weird thing is that no matter what, I couldn't get the constant tension clamp around the top of the back hose. It was around 1mm too thick and kept gettting pinched between the head and the hose. Busted my right hand to hell and back trying to push that hose over the lip of the pipe. I had to eventually give up and use a worm clamp 
I did notice that the front and rear hoses' clamps have different part numbers; yet I was shipped 4 in the same bag. Maybe that's the difference between the two part numbers. The thickness of the clamps for the front and back hose.

Bumping to top... I need to reread this thread and copy down the part numbers, as I still have a coolant leak around/behind the thermostat and I'm going to regasket pretty much everything, including replacing this hose. The leak is right beside the water pump (JUST replaced that) near the PS hardline, right at the gaskets behind the thermostat, the banjo fittings, and this bleeping hose. No chances, no prisoners.
