Thanks!
You do NOT have to warm the engine as that would be an oil mess unless you wait for a few hours.

Use a 1-1/8" 12 Pt Box Wrench with another Box Wrench for leverage.

The issue using a Deep Socket is that the torque is applied too far out causing the socket to twist off the fitting. With the box wrench there is no twisting off the fitting with all torque applied directly to the fitting flats.
