Procedure
Follow the procedure below to check the engine coolant level.
1. Open the access cover on the roof.
2. Open the radiator filler cap slowly in order to relieve the pressure. Remove the
filler cap after the pressure has been released.
3. Verify that the coolant level of the radiator is 3/4-inch below the bottom of the
filler neck. Add more coolant if necessary to maintain this level.
4. Inspect the radiator filler cap and filler cap seal for damage. Clean the radiator
filler cap or replace it if necessary.
5. Re-install the radiator filler cap.
NOTICE: Solutions of antifreeze and supplemental coolant additives MUST be
used year-round. Automotive-type coolants do not contain the correct coolant
additives to protect heavy-duty diesel engines. They often contain a high
concentration of silicates which can damage the engine and cooling system. Refer
to engine operator’s manual for coolant recommendations.
WARNING
Burn hazard. Engine coolant is hot and under pressure at operating temperature. It
can cause severe personal injury.
f Check the coolant level only after the engine has been shut down and is cool.
WARNING
Burn hazard. Coolant can contain alkali.
f Avoid coolant contact with skin and eyes.
