Merry Christmas...

Re: Heater Valve Repair

Awesome write-up. I didn't realize the valve sold by Nissan had been redesigned. Thanks!

Re: Heater Valve Repair

An additional reason to pull the dash is to replace that short section of heater hose that connects the valve with the heater core. That hose in my 79ZX was hard as a rock. I had to carefully use a Dremel tool with a small cut off wheel to remove it from the heater core pipe, very slowly so I did not nick or cut the pipe. The original Nissan hose for that spot is molded with a slight bend, rather than being a straight piece of normal hose, but you can find slightly bent hose sections and any parts store, just using your calibrated eyeball to pick the right one. It is only about a 15 degree bend. The problem is that the hose is so short that bending a straight piece can place too much stress and cause early failure and leaks.

And just like that valve, if the hose leaks, it is a miserable chore trying to replace it without taking out the dash and moving the heater box.

Re: Heater Valve Repair

Mind if I insert this into the document. It would be a good preemptive fix.

Re: Heater Valve Repair

By all means. That is why I mentioned it, because that short hose is very easy to overlook.

Re: Heater Valve Repair

Sorry this might but a dumb question but would that new heater valve available through Nissan work for a 77 280z?

Re: Heater Valve Repair

Don't know. You'd have to know what yours looks like. Z-store does not show one for the 77. Go here

http://www.thezstore.com/page/TZS/CTGY/SHC03

and compare yours with the 75 and 79/83. You may just have to rebuild it.
