RAM 3500 Truck 4WD L6-5.9L DSL Turbo VIN C (2002)
Valve Clearance: Adjustments
STANDARD PROCEDURE-VALVE LASH ADJUSTMENT AND VERIFICATION
NOTE: To obtain accurate readings, valve lash measurements AND adjustments should only be performed when the engine coolant temperature is
less than 60°C (140°F).
The 24-valve overhead system is a "low-maintenance" design. Routine adjustments are no longer necessary, however, measurement should still take
place when trouble-shooting performance problems, or upon completion of a repair that includes removal and installation of the valve train
components.
1. Disconnect battery negative cables.
2. Remove cylinder head cover (Fig. 47).
