Structure
• The engine front cover is made of aluminum alloy, and is integrated with the No.3 engine-mounting bracket, to
improve noise absorption and decrease weight.
• The hole for crankshaft pulley positioning bolt, the service hole for unlocking the chain adjuster ratchet, and the
service hole for securing the tensioner arm when loosening the timing chain, are on the engine front cover.
• The oil line and the integrated oil filter are on the L3 engine front cover.
