Checking for Coolant Leaks
Perform daily visual checks for cooling system leaks. Look for an accumulation of coolant when the engine is running and when it is stopped.
Warning: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked.
Coolant Inhibitors
The inhibitors in antifreeze solutions must be replenished with an approved corrosion inhibitor supplement when indicated by testing the coolant. for the listing of required intervals using the recommended coolants for required test intervals, inhibitor levels, and approved inhibitors.
The cooling system is protected by a Supplemental Coolant Additive element. In addition, the engine can be equipped with a coolant filter/inhibitor system as an installed option or as an after-sale item.
Coolant Drain Interval
A coolant system properly maintained and protected with supplemental coolant inhibitors can be operated up to the intervals listed. At these intervals the coolant must be drained and disposed of in an environmentally responsible manner according to state and/or federal Environmental Protection Agency (EPA) recommendations.
