Engine Operation
Starting after an extended shutdown period (parked for more than 30 days)
- Engine oil pressure MUST be indicated on the fuel gauge within 15 seconds after startup. If oil pressure does not appear, consult Chrysler or Cummins before driving the truck.
- Idle the engine for 3 to 5 minutes before loading the engine.
Ether
- DO NOT USE ETHER as a starting aid in cold weather. The intake manifold heater may ignite the ether in the manifold and cause an explosion.
Idle / Warm-up / Cool-down
- Idling for longer than 15 minutes should be avoided.
- Do not operate at full speed or load until the coolant reaches normal operating range.
- Do not operate above low idle until oil pressure is indicated.
- After extended high power operation, idle the engine for 3-5 minutes to cool the turbocharger before shutting down the engine.
