SERIES 60 ON-HIGHWAY ENGINE OPERATOR'S GUIDE

Idling

The common belief that idling a diesel

engine causes no engine damage is

wrong. Idling produces sulfuric acid ,

which breaks down the oil and eats

into bearings, rings, valve stems and

engine surfaces. If you must idle

the engine for cab heat or cooling,

the high idle function of the Cruise

Control switches should be used. An

idle sp eed of 1100 rpm should be

enough to provide cab heat in above

32°F(0°C)ambients.

Winter Fronts

Awinterfrontmaybeusedtoimprove

cab heating while idling. At least 25%

of the g ri ll opening should rem ain

open i n sectioned stripes that run

perpendicular to the charge air cooler

tube ﬂow direction. This assures even

cooling across each tube and reduces

header to tube stress and possible

failure. Winter fronts should on ly be

used when the ambient temperature

remains below 10° F (-12.2° C).
