This can prevent major repairs at a later date. 1. Inspect the air cleaner service indicator (if equipped). Service the air cleaner element when the indictor shows red. Refer to truck manufacturer's maintenance manual, for procedure to change the air cleaner element. 2. Inspect the coolant level. The level must be to the bottom of the radiator filler neck. 3. Measure the crankcase oil level. The oil level must be between the ADD and FULL marks on the dipstick.4. Disconnect any battery chargers that are not protected against the starter current drain.
