INITIAL SETUP: Maintenance Level Operator Personnel Required Driver Equipment Condition MASTER SWITCH ON OPERATION NOTE The engine coolant heater is a kit installed to prepare the carrier for extreme cold. The kit heats coolant, and circulates the heater coolant through the engine and a heat exchanger plate in the battery compartment. The kit is designed to operate safely while left alone for up to 12 hours. The engine coolant heater controls are on a control box mounted below the middle windshield. Two manual shutoff valves in the power plant compartment let you stop the flow of coolant through the engine coolant heater when it’s not running. Here’s how to turn it on: 1. Make sure MASTER SWITCH is ON. 2. Turn FUEL PUMP switch OFF. 3. Do the During Preventive Maintenance Checks and Services (WP 0057 00). 4. Open both coolant valves by turning valve handles counterclockwise as far as they’ll go. The coolant shutoff valve is at the upper right front corner of the engine behind the secondary fuel filter. The coolant diverting valve is on the lower left front corner of the engine. 0040 00-1
