I was dumb and used an impact drill on my other one. Went to loosen my oil filter and boom! Now I know.

The Assenmacher Specialty Tools TOY 640 Oil Filter Socket Wrench is one of the best tools I have ever purchased from Amazon.It is a very high quality tool, and fits perfectly on my 5th gen Toyota 4Runner filter cover.The Toyota dealer who did my last oil change must have used an impact wrench to install the oil filter cover.I had to use a 24" breaker-bar with my new TOY-640 to get the old stuck and cracked plastic filter cover off my engine.I replaced the broken plastic cover with an aluminum filter cover and torqued it to 25 Nm.The design and manufacturing tolerances of the TOY-640 socket wrench are so good, that it fits as snug as physically possible, but does not get stuck on the filter cover.

Dealer tightened the oil filter cap insanely tight. Or dealer did not even change the filter last time and the mechanic did it more than a year ago. Because when I finally removed the filter cup using the impact and this tool the filter inside was not the original Toyota one. Good tool. I broke another brand key with 3/8 hole but this one with 24mm socket worked well. Happy customer.

I had another style of filter housing wrench and it is not nearly as good as this one. This is a genuine Toyota part made of aluminum and it works great. If you do your own oil changes and need a wrench, I highly recommend this one. Should have bought this a while ago. Just insure it fits your vehicle, Toyota has a couple different sizes. This will fit a 2016 4 Runner and many other vehicles.

Used a few minutes ago for the first time on my new (used) 2012 Toyota Matrix. As its name says, it is a specialty tool meant to do one job, and do that job well. The fit is absolutely perfect; no slippage whatsoever. It is all-metal construction, so durability should not be an issue, particularly if you have to exert excessive torque to remove the cartridge housing from an over zealous mechanic. I suppose you could buy an inferior copy of this product, but I'm not sure why you would. Buy it once, use it forever. Excellent product.

Works perfectly for Mobil-1 M1-103 oil filters. Very handy tool to have for oil changes, especially if your cars use the same size.Only gripe is its odd socket size. I had to buy a 1/2" socket wrench to use the appropriate socket, as I couldn't find any sockets that use a smaller wrench. Not that big of a deal, as having a 1/2" wrench around can be useful anyway, and others may be able to find the proper socket for their smaller wrenches anyway.

I recently bought my 2010 Corolla 1.8 from a family member who was going out of country to work for 2 years and no longer needed the car. They bought it brand new in Feb 2010 and it has had all of its oil changes from Toyota dealerships since new.It was time for an oil change last monnth, and I put the car on the small midrise sissor lift I have in my home shop. I attached the Assenmacher tool to a 1/2 drive ratchet with the correct socket and attempted to remove the filter housing. It would not budge. I decided to wait a while to let the housing area cool off since the housing is made of plastic and threads into metal, resulting in a mismatch of thermal expansion characterics (bad design IMHO). I tried again after 3 hours, it still would not loosen. I then got a 2.5 foot breaker bar and tried again; it would not loosen.About this time, I got a litte worried and decided to check the net for problems with removing this filter housing. I read one report where the housing was so tight, they had to cut the housing off and buy a new one. I finally decided to use my 1/2" air impact and attempt to remove it. I was initally concerned that the impact would break the stub end off the Assenmacher tool, but I had nothing to loose by trying. I began using the impact and after 5 seconds of use, I noticed the plastic housing finally starting to loosen. A couple more seconds and it came off.I inspected the threaded area of the housing closely to see if it has somehow been cross threaded during installation at the toyota dealership; no problems found. I guess some oil lube flunky at the dealership has installed it with an air impact gun. I completed the oil drain and reinstalled the filter and new O ring and torqued to required specification of 18 foot lbs.Praise the Assenmacher tool, it withstood the hammering of my air impact and allowed me to remove this greatly overtightend filter housing on my 2010 Corolla 1.8.THIS TOOL IS WORTH ITS WEIGHT IN GOLD. BUY NO OTHER.One final comment: Just because someone takes their car to dealerships does not need a job as simple as an oil change will be done correctly. Do your own work and ensure it is done properly is you have the necessary tools and skills.

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.
