Heater system/Fresh air unit 140 (With A/C)

This group includes hoses and the water return pipe for the heater circuit, a T-pipe for distribution, a vacuum bellow that controls the shutter movement, plus mounting hardware such as screw, washer, sheet metal nut and catch washer for fitting to the panel and cowl. When overhauling the system, hose ends, return pipe and the vacuum bellow's diaphragm are recurring inspection points – leakage here results in weak heat or shutters that stick in one position.

These parts are intended for the 140 in versions fitted with air conditioning, where the routing differs from cars without A/C.
