Heater system/Fresh air unit Volvo Amazon (B18)

Brittle heater hoses, leaking gaskets and a fresh air grille that no longer seals are classic complaints on the 122 with B18 – the result is cold feet, fogged-up windows and drafts in the cabin. When the system is taken apart during a restoration, it is often the small parts around the hose routing that are missing or worn out.

This group includes hoses and air intake hoses, hose clamps, gaskets, washers, screws, mounts and plugs to seal and re-route the heater and fresh air ducts. These are parts that cover the whole way from the fresh air intake to the heater core, so the airflow is directed correctly and no unwanted holes let in engine bay air.

A typical checkpoint on this job is the hose connections: old clamps lose their tension and the gaskets harden, which causes false air and poor heat. Replacing the hose, clamp and gasket at the same time usually gives a noticeably tighter and warmer cabin.
