Cold Weather Starting And Operation-Internal Starting Aid

The internal starting aid alters fuel injector pump timing to enhance starting. Operating time of the starting aid is dependent upon coolant temperature and throttle position.

Use the following procedure:

Put throttle (A) in SLOW IDLE (900 rpm) position.

Avoid unnecessary engine idling. Operate at minimum of 1200 rpm if idling longer than three minutes.

Start engine. Leave throttle in slow idle position.

Operating Characteristics:

• Operating cycle time varies from 3-30 seconds depending on temperature after engine is started.
• Moving throttle from the slow idle position will cancel starting aid cycle.
• Engine may run rougher and have increased diesel knock after the end of starting aid cycle. This is normal. Engine will run smoother as engine temperature increases.
