www.changlin.com.cn After the CAC has been thoroughly cleaned of all oil and debris with solvent, wash the CAC internally with hot soapy water to remove the remaining solvent. Rinse thoroughly with clean water. Blow compressed air into the CAC in the opposite direction of normal air flow until the CAC is dry internally. Refer to the vehicle manufacturer's instructions for installation. Air Cleaner Restriction Maximum intake air restriction is 635 mm [25.0 in.] of water for turbocharged engines. Naturally aspirated engines have a maximum restriction of 510 mm [20.0 in.] of water. The engine must be operated at rated RPM and full load to check maximum intake air restriction.
Replace the air cleaner element when the restriction reaches the maximum allowable limit or clean according to the manufacturer's recommendations. NOTE: Follow the manufacturer's instructions when cleaning or replacing the air cleaner element. Change the air cleaner service indicator, if equipped. Change the filter element when the red indicator flag (2) is at the raised position in the window (1). After the air cleaner has been serviced, reset the button (3) in the end of the service indicator. NOTE: Never operate the engine without an air cleaner. Intake air must be filtered to prevent dirt and debris from entering the engine and causing premature wear. 46 / 149 pages
