2004 - 2010 Toyota Sienna VVT-i Oil Cooler Line Replacement

This is a common failure on Toyota Siennas that can cause major damage if not fixed. I was lucky and mine failed as I was pulling into my neighborhood.
I bought part # 15772-31030 straight from the dealership for about $38. It says it doesn't fit the Sienna, but it has the same engine as the Highlander and several others and it fit great.
Here is the link referencing the LSC for it if you care to read it, but DO NOT buy the part they say to in this file. That only replaces the rubber hose with another rubber hose: static.nhtsa.g...
Diagram of how it goes together with washers and everything:

Steps to complete this:
Drain the rest of your oil and replace plug
Remove plastic plate covering the VVT-i line
Remove top banjo bolt - 17mm
Remove bracket bolt - 10mm
Remove serpentine belt (plenty of videos online showing how)
Remove both power steering bolts and let it hang - 14 mm
Remove bottom banjo bolt - 17 mm
Pull the old line out put it all back together in reverse order!
In the video I had just started putting it back together. Here are some notes from after I got it fully installed:
I had a fit getting the Power Steering pump back in. Slide the top bolt in before you try to line it back up. I put the bottom in first then couldn't get the top bolt to fit back up in there and had to take the bottom off again. Also, be very careful and get the bolts started by hand first. The holes are aluminum and when I put the bottom bolt back in for the second time I cross-threaded and stripped the hole because I was frustrated and trying to go too fast.

I really appreciate you taking the time sharing. I have a 2008 Sienna that just blew the original equipped oil cooler hose and thank Goodness I didn’t experience the possible catastrophic engine damage… And after watching the Car Care Nut channel regarding the specifics about replacing the old with the new updated metal hose, he also mentioned replacing the hose you had just done… So thanks again for your consideration in helping another DIYer out. Much blessings to you!

This issue affects Toyotas and Lexus with the 2GR-FE 3.5L V6 engines.Toyota issued a TSB for this issue and superceded the line with an "upgraded" line with a rubber section. A subsequent TSB replaced the upgraded line with an all-metal line. Many owners didn't receive notice about this problem. [edit] This is technically not an oil cooler line. It supplies oil to the rear bank VVT-i gear. If you have a 2GR-FE engine with tow package, you'll have an actual oil cooler line that is in the lower front of your engine. It's a short double line that may have rubber sections. These are known to fail and can cause a catastrophic loss of oil.

I have the same Sienna and I’m looking into the common issues. Glad I found your video.

Thank you for this vid. I have a 2009 Camry with the 2GR-FE that I bought in 2019, and made sure that the original equipment hose had been replaced under the TSB LSC90 campaign. Unfortunately, evidently early replacements were nothing but another rubber hose with some iron added to it, so I'm going to replace the replacement with an all-metal hose.

Thanks bro. I had the same Sienna and my vvti line is rubber. Will try to do it like you did. However my level is to change the thermostat.It's 2006-2010.

This only applies to the 2007-2010 Sienna and other Toyotas with the 3.5 engine. The 2004-2006 Sienna has a 3.3 engine and doesn't have these lines.

Thanks! i have a 2007 Avalon and like you said it was sated that the part does not fit my car. I am confident it fits fine like yours. I am installing a new to me engine so it should be an easy install. appreciate the info.

For this 2008 sienna, do you gave front rubber oil cooler line which is located near oil filter, i was reading that line is very critical to replace but i coul not find in front of my car.
