Heater Control Valve 1970-73 (240Z)

Nissan

One of the most common reasons why your 240Z's heater system may not be working right is a bad control valve. This valve can cause your heater to stay on all the time, not turn on at all, or spill engine coolant all over your carpet! Also known as the Cock-Heater valve.
