I called my dealership parts department to order a special tool like this...but they claimed ignorance of this tool...saying their mechanics buy whatever they can find on the market and that Toyota doesn't manufacture a special tool like this one. This tool fit my 2008 Toyota Sienna CE oil filter housing perfectly. The photo shown above is not the same tool, it is actually silver colored and is cast aluminum, and has no hole in the middle. It's internal width measures 64.24 mm by dial caliper. To operate it, I used a 15/16 deep socket attached to a large torque wrench. This creates a snugger fit than the other persons suggestion to use a 24mm socket. The removal nut is a 6 sided hex measuring .919 inches. A 15/16 socket fits this tighter than 24 mm does. Unfortunately for me, the stealership from La Vista, NE, (Perf...), had previously done my oil changes and they seriously overtorqued the oil filter housing the last time they changed it. You are only supposed to torque it on at 25 N m (only about 18 lb ft) to install it, but guess what? My 1/2 socket driver, two foot long torque wrench was set to 87 lb ft and it came loose at some force beyond 87 lb ft because the wrench clicked well before it loosened. (This is the same stealership that tried to tell me my warranty was voided if I didn't rotate my tires.) The plastic $5 Fram oil filter wrench from "stuff-mart" is for 65/67 mm, not 64 mm like the oil filter housing appears to actually be. I think that's why this Assenmacher wrench part number ASTTOY640 has the number 64 in it, because it's meant for a 64mm fluted housing. I tried modding the plastic Fram one as someone else suggested by sawing off the 67 mm portion to no avail...it slips anyway. This Assenmacher filter wrench is awesome for stuck filter housings...it works so much better than the plastic filter wrenches. Don't waste your money on the plastic ones that are the wrong size, buy this one instead. And if you have a Sienna minivan, the oil change was easier than I thought...no plastic splash guard with a zillion plastic screws to remove...just jack up the right front a couple inches and it's really easy to access. And one final tip: don't leave the small o ring on the oil filter housing when you go to insert the special plastic tubing adaptor to drain your filter housing before removal. My new paper element filter came with the drain tool and had instructions in the box which showed the o ring being left on. Don't do it, it'll make a mess because you'll have to hold the draining device on by hand for 5 minutes and it will leak. It's supposed to insert, click and lock into place for hands free draining of the oil from inside the filter housing, but to get it to do this the small o ring has to be out of the way.
