3.13 ENGINE RADIATOR FILL PROCEDURE - PERKINS
& CATERPILLAR
DUE TO THE CONFIGURATION OF THE COOLING SYSTEM,
SOME ENGINES REQUIRE A SPECIAL RADIATOR FILL PRO-
CEDURE. FAILURE TO FOLLOW THIS PROCEDURE CAN
RESULT IN DAMAGE TO THE ENGINE.
THE FOLLOWING FILL PROCEDURE SHOULD ONLY BE PERFORMED WHEN THE
ENGINE IS COLD.
ENGINE COOLANT IS UNDER PRESSURE. DO NOT REMOVE THE RADIATOR CAP
WHILE THE ENGINE IS WARM.
NOTE: If the radiator cap is removed at any time after the follow-
ing steps are performed, coolant will flow out regardless of
whether the engine is cold or hot.
1. Remove radiator cap and reservoir cap.
2. Fill radiator to the top. Allow enough time for coolant to
properly settle in radiator and add coolant as necessary
to top off.
3. Install radiator cap on radiator.
4. Remove plug from adapter and add coolant at this loca-
tion until radiator hose is full of coolant.
5. Using sealant JLG P/N 0100020 (Loctite #567), install
plug back into the adapter.
