The warehouse sorting label contains a bold handwritten marker catalog notation reading: "2002". This specialized pre-formed heater bypass line routes coolant securely between the intake manifold junction and the primary water temperature switch housing block. Formed from high-grade heat-resistant EPDM compound material, it prevents pressure collapses, interior dry-rotting, and vacuum loss across the iconic M10 engine platform.
