Hello,
What oil filter wrench is best for removing the difficult to reach oil filter on the 900/700 turbo cars? I accidentally rolled over my filter wrench that didn't work very well anyway. I read on TB that the fram filter wrench/tool (the long one) works well but, I am not sure if it specified that it works for the turbo's or the N/A cars, or both. The hard oil line makes it even harder to get a filter wrench in there. Thanks.

This thread is in ALL/ALL, but it is supposed to be specific to the "900/700 turbo," a car on which I haven't ever had to change an oil filter.



The filters I buy don't have anything to mate with the cup adapters, but my collection shows I remember them. On Volvos, the only time I've needed to use a tool to loosen a filter is when someone else tightened it. Then I like #2 above.

GREAT TRUTHS THAT ADULTS HAVE LEARNED:
Today's mighty oak is just yesterday's nut that held its ground.

Cheapest, easiest and most compact filter wrench I've used is the single lever flex jaw type. They need minimal clearance and even with the straight handle you can easily use them at a bit of an angle so work fine in both turbo and NA filter locations. Easily stores in tool boxes as well. Under $10 -currently $3.99 at Autozone for the OEMTools brand that fits 2-1/4" to 4-1/4". Two seconds to easily flip the spring loaded jaw over the end of the filter at an angle to give it a little twist to get it started. Only if the oil filter was frozen on would you need something that would fully grip the filter, like the three fingered design that goes on the end of a ratchet using a universal joint on the end if needed to get at odd angles as in the turbo. Trickiest bit as always is to get the filter off with the least amount of spillage, being sure to wipe oil off rubber engine mounts, hoses and the like. Wipe a good coat of oil on the rubber filter seal ring and hand tighten -don't need a wrench, just makes it harder for the next guy.

Guys,
Thanks for the replies. I have that orange handled wrench. Every time that I have used it, it has crushed the filter (in the spot where the small part of the tool meets the filter), and I chickened out, thinking that it would mangle it too much to get it off and I used something else to remove it. I think that I will get a flat piece of metal to put in that contact point where it crushes it to distribute the force out some. I put motorkote on the sealing ring, and they are still stubborn to remove sometimes.

I will also look into the other type of wrench mentioned, that goes over the end of the filter. if there is clearence to use it on the B230FT. It is tight in there. Thanks.

My personal favorite is the canvas strap type that you use with a 1/2” drive ratchet or add a ratchet extension if the filter is buried back in a tight place. One size fits all. The strap applies even pressure all the way around the filter so the filter doesn’t get crushed.

Another type to use would be the "cup" type that fits over the end of the filter and has provision for a 3/8ths drive ratchet/extension. Harbor Freight sells a kit that has all the sizes for less than $10. The Turbo models use the same filter as NA motors. -- Dave

Have had a couple of those cup type that fit over the filter, good design in principle. The plastic one wouldn't stand up to my 3/8 drive ratchet. The metal one, China I’m guessing, separated at the spot welds. Both instances required a screwdriver through the filter to loosen. Which were only hand tightened at installation. Not sure what I’m doing next.....
