I never remove when changing oil filter. Just unscrew the canister. Maybe a little more messy but I don't see the point of draining the canister before removing it. Anybody else skipping this step?
Same here. The 3/8 square hole in the cap makes it easy to remove and reinstall the canister w/o special tools. I suppose if it ever comes loose I'll change the little valve thingy but until then I just throw away the extra parts.
I think this thread is discussing how to change the filter, not whether to change it.>I replace my oil cartridge filter on our 3.5L 2G-FE every 5 k miles. We have 3 Toyotas with the 3.5. An '07 Sienna, '08 Highlander and the '10 Rav4. My local Toyota dealership sells a case of 10 cartridge oil filters for $40 out the door. Hendrix Toyota of Apex NC
Why wouldnt you change your oil filter cartridge? A proper oil service is the cheapest insurance you can give your car.
BTW, the '07 Sienna just passed 224 k miles. Beautiful condition.
I remove it and use the drain fitting with a hose. conaford is correct, I have seen a little bit of debris that likes to collect down there. Not every oil change but occasionally. I wouldn't say it is necessary though unless you enjoy changing oil and don't mind the extra couple of steps. I enjoy the whole process, so it's fun for me. I seem to get oil drips/splatter even with draining the canister. One tip is to remove the o-ring before inserting the plastic drain adapter. I fought it in the beginning because the adapter wouldn't seat and lock with the o-ring in place.It washes any debris that settled out in that part of the housing which you’re about to re-use. Think it’s worth doing it just for that reason.
