7.7 Checking 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.
