OIL IN COOLANT INSPECTION
WARN I N G
Personal injury can result from hot coolant, steam and alkali. At operating temperature,
engine coolant is hot and under pressure. Radiator and all lines to heaters or engine
contain hot coolant or steam. Any contact can cause severe burns. Allow engine and
coolant to cool before slowly removing filler cap to relieve cooling system pressure.
Engine must be stopped and radiator cap is cool enough to touch with your bare hand.
Failure to follow this warning may result in injury or death to personnel.
1. Open door (Figure 13, Item 2) on machine.
2. Slowly remove cooling system cap (Figure 13, Item 1) from coolant tank (Figure 13, Item 3).
3. Inspect coolant tank for oils.
a. If oil is black and milky in coolant tank, replace engine oil cooler (WP 0084).
b. If oil is brown in color and appears clean, replace transmission cooler (WP 0042).
If no oil is present in coolant tank, return to Troubleshooting.
