Heater system/Fresh air unit Volvo Amazon (B20)

Rattling hose clamps, hardened rubber hoses and a blocked drain pipe are classic troubles on the 122 with the B20 engine – often noticed as fogged-up windows, a damp smell or a heater that loses output. This category gathers parts to seal and rebuild the heater and fresh-air system on the late 122 model years (the B20 was introduced in August 1968 for the final two model years).

The group includes rubber hoses and air intake hoses in several sizes, hose clamps, gaskets, washers, screws plus a plug and drain pipe. During an overhaul, the hose connections and the drain pipe are exactly the typical checkpoints – a clogged drain pipe collects water in the fan housing and causes condensation and rust, while cracked hoses let in unwanted air and worsen the air distribution. By replacing hoses, clamps and gaskets at the same time you get a sealed system and even heat without chasing down small leaks afterwards.
