QUICK EASY STRAP WRENCH
The diameter of a diesel engine oil filter was larger than my biggest filter wrench, so I made this strap wrench from an old spark plug socket, worn-out poly-V serpentine belt, and a short length of PVC 1/2″ schedule 40 pipe. I used an angle grinder to quickly slot opposite sides of the socket.  I fit the belt thru the slots and then tapped a short length of PVC pipe into the socket. You want just enough to keep the belt in place, but not enough to prevent the belt from sliding. Slide the belt in the slot to adjust for size. Trim the belt’s length as desired.
