ReferenceRefer to Special Instruction, REHS9204 for the installation procedure of the new solenoid valve group.

Description of Change: The new prelube solenoid valve has a two-way design replacing the previous three-way design. The new two-way design, along with mounting the valve vertically, reduces the chance of an air/gas leak.
