NOTE 2 Follow the steps below to install the CCV. 1. Install the CCV module on the engine. Tighten and torque the six bolts using a torque wrench to 16.2 +/- 1.5 lb-ft (22.0 +/- 2.0 N·m). 2. Attach electrical connector and inlet/outlet hoses. The engine and fuel module should be operated in cold climates with accepta- ble cold climate fuel blends which no- ticeably reduces wax gelling in the fuel filter cartridge.

The fuel module in- cludes a 12V preheater to support pre- heat of the fuel for initial start-up in mild climates. Failure to operate with acceptable cold climate fuel may result in insufficient fuel flow to the fuel injec- tion system. NOTE The fuel filter and the hand pump are located on the left-hand side of the en- gine, as viewed from the driver's seat.

Description NOTE The fuel filter/water separator module provides fine-particle filtration, water separation, water-in fuel-sensing, automatic water draining, lifetime purification of drained water with a charcoal filter, 12V preheating and system manual priming in a singular easy to service module. If B6-B20 biodiesel fuel is used, the fuel filter must be changed every 25,000 mi (40,000 km). WARNING When removing the fuel filter, a quanti- ty of fuel will escape.
