Snap-on’ offers the 3/8” Drive 6-point 10mm 6.4L Turbo Inlet Pipe Socket, No. S6210. This tool is designed to access the bolts that hold the turbo inlet pipes to the turbo on 6.4L diesel engines. There are six bolts with restricted access between the turbo and the firewall. Removal of these bolts below the EGR OC pipe is especially difficult and time consuming without a 10mm Turbo Inlet Pipe Socket, such as the Snap-on S6210.
