It takes the multi fluted oil filter cap wrench to remove it after you unscrew the leashed cap covering the oil filter drain valve. Assenmacher 2175 is the tool you need to take it off.

He wants to replace the #3 seal in the above pdf. No need to remove the filter with the Assenmacher tool.

Thanks didnt catch that just remove whole housing and replace the number 3 seal and you will be good to go.
