OAT coolant (conforming to MS-12106) as soon as

possible.

Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine

coolant (antifreeze), and to ensure that engine coolant

(antifreeze) will return to the radiator from the coolant

recovery tank.
The cap should be inspected and cleaned if there is any

accumulation of foreign material on the sealing surfaces.

WARNING!

Do not open hot engine cooling system. Never add

engine coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the cap to cool

system is hot or under pressure.

Do not use a pressure cap other than the one
