Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.

If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.

Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
