When checking the radiator coolant level, shut down engine, let
the engine and radiator cool down, then check the coolant
recovery tank. If the coolant level in the coolant recovery tank is
near the upper limit, there is enough coolant in the radiator.
Loosen the radiator cap gradually to release the internal
pressure before removing the radiator cap.
If the coolant level in the coolant recovery tank is below the lower
limit, add coolant.

personal injury. Do not allow alkali to contact the skin, the eyes,
or the mouth.
Allow cooling system components to cool before you drain the
cooling system.
Hot oil and hot components can cause personal injury. Do not
allow hot oil or hot components to contact the skin.
Remove hydraulic tank filter plug only after the engine has been
stopped. Make sure that the hydraulic tank filter plug is cool

system, or in the cooling system before you disconnect any
lines, fittings, or related items.
