A 2 speed fan clutch works to not only minimize noise but keep the engine at optimal temperatures. The fact is that even the busiest shunt tractors may idle 20% of the time and modern EPA regulated DOT diesel engines struggle in yard tractor platforms to reach the temperatures required for the emission control systems to function properly. Autocar’s standard 2 speed fan clutch on their DOT equipment helps with getting the engine up to and maintaining proper operating temperatures which means longer periods of time between emission system maintenance and repair.
