of the connecting cable shall withstand normal operating stresses in low ambient temperature (down to minus 60°F) without cracking or loss of dielectric capacity. All heater lead wires shall be installed without interfering with vehicle component operation, and without loose excess wire. Provisions for stowage of the cable shall be provided in the vehicle cab, and shall provide

positive cable retention during vehicle operation. Heaters shall be furnished as follows:

(a) A coolant heater, 1500-watt minimum rating, shall be installed in the engine block or in the lower coolant inlet hose. An engine thermostat with an operating range of

170°F to 195°F shall be installed.

(b) An immersion type engine oil heater, 300-watt minimum rating, with 170°F to 195°F

thermostat, shall be installed in the oil pan through any convenient opening.

(c) The battery heater shall have a capacity adequate to maintain the battery electrolyte at a temperature of not less than 10°F during vehicle exposure in ambient air temperatures as low as minus 60°F, and shall embody a thermostat to limit the temperature of the electrolyte to not more than 80°F.

(d) A fuel warmer or pre-heater shall be provided to prevent clogging of fuel filters due

to wax crystallization in the fuel. The fuel warmer shall use engine coolant to transfer

sufficient heat to the diesel fuel to heat it from an inlet temperature of minus 40°F to an outlet temperature of plus 9°F, with a flow rate not less than the maximum fuel demand of the engine fuel system. A coolant shutoff valve shall be provided for the coolant inlet side of the fuel warmer unit.

3.4.2 Electrical system. The electrical systems shall be in accordance with Federal Motor

Carrier Safety Regulations 393.27 through 393.31 and 393.33.

The engine starting equipment shall include an ether starting system or a glow plug. If an ether system is furnished in lieu of a glow plug, it shall be of the measured shot type. The measured shot type ether system shall be key operated or manually operated from the driver's compartment, shall have a reservoir of not less than 12 fluid ounces, and shall be inoperative with the engine warm.

3.4.2.2 Lighting. The lighting system shall be a nominal 12 volts. All vehicle lights and reflectors shall conform to Federal Motor Carrier Safety Regulations 393.12, 393.19, 393.20, and
