YNF18866 369-3869 oil filler cap helps seal the engine oil filling opening and protect the lubrication system.
The YNF18866 369-3869 Engine Oil Filler Cap is a lubrication system component designed for compatible C7.1 engine and CAT 320D2 excavator applications. The cap is installed at the engine oil filling opening and helps keep the lubrication system properly sealed during normal engine operation.
A secure oil filler cap helps prevent dust, dirt, and other external contaminants from entering the engine while helping retain engine oil within the lubrication system. Its construction is designed to withstand the heat, vibration, and operating conditions found around a diesel engine.
The C7.1 engine oil filler cap is suitable for routine engine maintenance and replacement applications. Replacing a missing, damaged, cracked, or poorly sealing cap helps maintain a clean and properly sealed oil filling system.
