Heater system/Fresh air unit Volvo Duett (B4B)

Cracked heater hoses, loosening fasteners and dried-out gaskets are classic age-related troubles on the 445's heating and fresh-air system – the warm air finds its way out before reaching the cabin, and condensation collects in the wrong directions. This category gathers the wear and sealing parts that keep the flow in place through the B4B and B16 years.The group includes air intake hose and hose for the air and heat routing, gaskets against leakage at the transitions, plus fastening hardware such as screw, nut, washer, spring washer and fasteners to clamp hoses and panels in place. During a restoration it is often the small details that decide the result – a worn-out spring washer or a tired fastener loses its grip and creates play throughout the whole routing.Check the hose ends and gasket surfaces at the same time as you replace the fasteners, so the sealed path between the element and jets becomes whole again.
