The APU is liquid cooled and requires coolant in order to operate at a safe temperature. Before beginning
this step, be sure you have the proper size water T for integrating into the existing cooling system. NOTICE:
Coolant temperatures can exceed 150°F, so be cautious when working with coolant lines to avoid burns.
●
Lift the truck hood; take note of the current truck
coolant level. In connecting this APU you will need
to add approximately two gallons of coolant to
make up for the additional coolant line volume.
●
Locate the coolant supply and coolant return lines
at the main truck engine. If unsure, check the
temperature. The return line will usually be hotter
than the supply line.
