78 280z 2+2 heater control valve leaking coolant

[s14280zx]

Does anyone know where I can get a heater control valve for my 78 280z 2+2? This is the one with a vacuum actuator on top. It is located under the dash against the firewall on the passenger side. Any help would be appreciated. Thanks PS. It has factory air.

I am mainly concerned with having defrost and maybe heat so I can drive it without the windshield fogging up on inside. Is there any other parts I could swap from other z's that would give me defrost? Could someone explain how and when this valve opens and closes, and how it operates. Any info would help me greatly, and I would appreciate any advice. Thanks, Jeff.

palladin over on zcar.com figured out a rebuild procedure and wrote it up. It seems pretty popular, especially for those on low budgets.

Zed Head hit a solid Home Run finding this information on zcar.com. This has been a HUGE issue for a while!! I checked on the NAPA part and it was running $9.99 in Houston(as of the date of this post). I haven't checked the $$$ or availability of the Nissan Part, but will soon and repost here.

My hat is off to Palladin over at ZCar.com for the hard work and writeup. Many thanks to both!!!

BTW: the NAPA part number is: BK 6601000, Nissan Part Number: 27116-P6500

kacrow: Did the NAPA repair item work for the heater control valve in your 76? Do you know whether it wpould work for a Series 1 Z?
