Thanks for the video. I did see the video from the Toyota tech "...and this bolt is hard to get out and for me to know". Sucks he wanted to show you most of the job, but not one of hard parts. This was a real help.
Glad it helped. I put in aftermarket parts and it only caused me chaos down the road. The valves shorted out and I was chasing a computer issue for a month. Hope it's not too late but I'd advise to use OEM parts. I don't recall what brand i installed.
Yes exactly. I just did mine and the hardest part was releasing the wire harness tube cable tube clamps at the back of the air intake manifold. Nice tip about the standing platform also, did not think of that. I was scared of the job since the truck was still running but it went pretty easy except for releasing those wire harness clamps. Got it done in one day in the cold on the gravel, 6 hours. I used a shopvac to vacuum the water out of the pump supply hose and will change the pumps and flutes later. The bypass is bull>>>. Do you want that crap leaking past the valve to the cat. Thank you. Wish I saw your video before biting the bullet and doing it. Your video should come up in the searches for this. I was scared of the job for a year when the dealer quoted the labor for it. Toyota built it to be worked on.
I think you meant the metal flanges on each side of the injection housing. See the video at 3:00. I think i just had to use a 10mm wrench, socket, or combination of both. You can only move the bolts a little bit at a time so just be patient. It's a pain but doable. Hope that helps.
Replace both injection fans and the valve switching mechanism which is probably under the intake manifold. I'm not familiar with the 4.7 but probably the same. BUY OEM parts, not aftermarket. I cannot stress this enough. My aftermarket parts went bad and caused her to be down for a month and I was at wits end. Good luck!
Right.? Less money if you figure you need to replace both pumps and flutes. I guess to be EPA compliant🤣. Good video though but I think I’ll do the bypass in like 1/2 a day less time.
Great video...im looking at the same right now. Seen Hedley enterprises or something of the sort offers a bypass kit. Is it a legit fix ? Emissions compliant?
I did it after a saw yor video 2 years ago. And now l have the same problem again. Is bad really bad invention about Toyota this trucks are not made for cold weather o raining weathers. Is bad

Love the light under the hood! And the booster platform. Great tips

this was helpful! Thank you
How do you get the bolt back in
How do you remove those air injector hoses?
Thank you & whats the torque you used to put the big part back?
I got a 2008 toyota tundra 4.7. Code p2436/p2438. Secondary air injector system. Bank 2 .. I don't know which part causing it. Help

@verywiseoldergentleman9125 valves on top in the 4.7 . Thanks much I'll start with th values because I think they are the culprits
Was this bank 1?
You should ALWAYS COVER INTAKE PORTS 1SMALL ANYTHING AND BYE BYE 5.7
Why not just do the bypass?

Is it a legit fix ? Emissions compliant?
@@stevemoore6349 not emission compliant. Not worked in my 2010 tundra 5.7. No good.
The Hewitt-tech bypass kit is plug and play, with block offs, and it is “compliant”. Because the kit’s components tell ECM everything is fine. 💪
Old school.motor do not have this nonsense going old school.

Use OEM parts. I haven't had an issue since the dealership installed OEM injection valves.
@@timlegler9216 thank you for the information I will.
