FWIW, I bought a huge crescent wrench, 16.5", that should help remove the filter no matter how tight the guys at Goodyear Auto made it.
#427 of 460 1st gen Sienna inline power steering filter?

I have a '99 Sienna and am investigating installing an inline power steering filter. I do not see a real good place to install on the supply side. Anyone accomplished this yet? TIA
#428 of 460 2011 Sienna Oil Leak
Aug 21, 2010 (5:00 am)
Within a week of driving home our new 2011 Sienna XLE, we saw oil on the garage floor. After several days back at the dealership service center, it turns out that there was a defective cam housing and gasket that required replacement, and it appears we aren't the only 2011 Sienna owners with this problem already. They pretty much have to remove the top half of the engine to replace the part. Yea, right, our new Sienna with half it's engine pulled out didn't please us at all. We've owned several Toyotas now, but this by far has been a major frustration. So it's fixed, but now we keep finding all sorts of little things like loose screws, dangling wires, broken wire harnesses, etc. We wouldn't wish this problem on anybody.

We didn't have an oil leak, but our 2011 Sienna LE is about to get a new Cam Shaft also. I reported an Engine Knock to the Dealer.

Hello. We are having this same issue of stalling when starting with our Sienna. I know this was posted a while ago, but wondering if you remember the 'fix' you found on Edmunds that was faxed to the repair house? Was it cleaning the IAC valve?

I think so but I sort of remember the problem as stalling when driving as well as starting.
#432 of 460 Cleaning the Intake Air Control Valve on 2001 Sienna
Aug 02, 2011 (12:19 pm)
If your Sienna won't idle when the engine is cold, then it is likely that the IAC valve is sticking.
Loosen your aircleaner cover by popping out the clips on the fender side. Wiggle it out of the holds on the engine side. Take the 4 inch airduct off the end by loosening the screw clamp.
Look down the duct with a flash light. You will see that the duct splits as it enters two throttle control units. The rear-most throttle control has a square hole in the bottom of it which you can see if you hold the duct straight and the light just right. Take a piece of plastic pipe or tubing with about a 3/8-1/2" inside diameter and stick it down to this square hole. Blow Gumout carburetor cleaner or a similar product through the tubing or pipe for about 3 seconds. Let it dry for about 30 minutes and repeat. Let it dry an hour and then reattach the airduct and the air cleaner cover. Start the car. It may take a few cranks to get any excess cleaner out of the system. Unless you have waited too long befor using this technique and thus damaged the IAC valve, this should solve the problem.
#433 of 460 OBD code P1150 - which one is Bank 2 Sensor 1?
Dec 04, 2011 (4:32 pm)
I got a code P1150 only 2000 Sienna LE, which I guess means Bank 2 Sensor 1. I am looking at Denso replacement part. It has upstream left (234-9007) and upstream right (234-9009). Is bank 2 sensor 1, upstream left, or right?

I am getting confusing results when looking for P1150. In one place it said it is for bank 2 sensor 1, and in another place it said bank 1 sensor 2. Anyone know exactly which one it is supposed to be?
