4.6 Engine Coolant
Check the coolant level of the radiator with the engine cold. After initial
filling of radiator to 3/4" below bottom of filler neck, maintain proper
level in overflow bottle daily.
NEVER remove radiator cap or drain plug while engine is hot!
Pressurized coolant can cause serious burns.
Shut off engine. Only remove radiator cap when it is cool enough to
touch with bare hands. Slowly loosen cap to relieve pressure first,
before removing it completely.
Solutions of antifreeze and supplemental coolant additives MUST be
used year-round. Automotive-type coolants do not contain the correct
coolant additives to protect heavy-duty diesel engines. They often
contain a high concentration of silicates which can damage the engine
and cooling system. Refer to engine Operator’s Manual for coolant
recommendations.
4.7 Trailer Maintenance
Tires - Keep tires inflated to the proper pressure as shown on the tire
sidewall, and check tread periodically for wear. Replace tires as
required.
Wheels - Check that lug nuts holding wheels are tight. Replace any
missing nuts immediately.
Axle Hubs - Grease axle hubs through grease fittings using a good
wheel bearing grease.
Brakes - Check operation of brakes before each trip.
Check level of brake fluid in actuator at front of trailer at regular
intervals. Fill to approximately 1" below top of reservoir using DOT-3
heavy-duty brake fluid. Tighten filler plug securely.
Note: If fluid level has fallen too low, bleed brake lines to remove any
air trapped in lines.
