6 Before Coolant Level
WARNING
• DO NOT service cooling system unless engine has been allowed to cool down. This is a pressurized cooling system and escaping steam or hot coolant will cause serious burns.
• DO NOT remove cooling system radiator cap when engine is hot. Allow engine to cool down. Loosen cap to first stop and let out any pressure from cooling system, then remove cap. Failure to follow this warning may cause serious burns.
• Wear effective eye, hand, and skin protection when handling coolants. Failure to do so may cause injury to personnel.
CAUTION
• Do not add water to pre-mixed antifreeze. If water is added to pre-mixed antifreeze, it will be diluted and will not pro-vide proper engine protection. Engine and/or cooling sys-tem damage may occur.
• Be sure to identify the type of antifreeze being added, or engine and/or cooling system damage may occur.
NOTE
• Some antifreeze is pre-mixed and requires no water.
• Traditional antifreeze requires mixing with an equal amount of water. Mix antifreeze and water before adding to machine cooling system to ensure proper 1:1 ratio is used.
• It is allowable to mix traditional and pre-mixed antifreeze in the same cooling system.

Before Coolant Level a. Open left front access door.
b. Check coolant level on coolant tank sight glass. If coolant level completely fills the sight glass, coolant level is okay. If coolant level can be seen in sight glass, coolant level is low.
c. Open radiator pressure cap access door and clean area around cap.
d. Remove cap and add coolant (WP 0022, Item 1) to maintain level between bottom of filler tube and top of sight glass.
e. Clean and inspect, then install pressure cap.
f. Close cap access door.
Coolant level is low or cap is damaged, or any coolant leak is evident.

CAUTION
• Engine oil level gauge has oil level markings on both sides.
One side is for checking when engine is stopped; the other side is for checking when engine is running at low idle with oil warm.
• Be sure to check correct side of gauge. Over- or under-filled engine crankcase may cause engine damage.
7 Before 0.2 Engine Oil
Level
a. Clean area around engine oil level gauge (dipstick) and fill cap.
b. Remove oil level gauge, clean, and reinstall. Remove oil level gauge and check level of oil.
Maintain oil level between the marks on oil level gauge.
