datsun40146 Posted February 10, 2007 Share #1 Posted February 10, 2007 Hey guys, is there an alternative/better replacement for the stock heater control valve for a 77 Z with factory A/C? After looking over this site and hybridz I found that a ford diesel or mack truck valve will work in a Z but the heater has to be cable operated. Mine uses vaccum like most other 77 and up Zs. The water leaks and soaked flooring routine is getting old. You can no longer order the vaccume heater valve through MSA, courtsynissan, or every dealer I called. Is there any alternative to this part? Link to comment Share on other sites More sharing options...
sblake01 Posted February 10, 2007 Share #2 Posted February 10, 2007 I think the manual valve is still available. At least it was about two and a half years ago when I changed mine. 27190-N3100 was the number and it was only about 12 bucks. I don't know how that would work out with your cables, controls, etc. Mine is a 78 non-a/c car with an aftermarket a/c system so it still has the manual controls.

zKars Posted March 17, 2009 Share #4 Posted March 17, 2009 Seems to me that Zman of washington has advertized that he can rebuild them. Give him a try.http://www.zspecialties.com/ Link to comment Share on other sites More sharing options...
sblake01 Posted March 17, 2009 Share #5 Posted March 17, 2009 Since this thread (2 years old) I've had my old one apart and I'm pretty sure I could rebuild it. Link to comment Share on other sites More sharing options...

sblake01 Posted March 17, 2009 Share #7 Posted March 17, 2009 (edited) This topic popped up on a search.So i thought i'd update it.My 810 valve is frozen......You should still be able to get the one for an 810 believe it or not. 27116-Q0100. Try that number. It's been a while since I bought mine but there aren't that many 810s around so I'll bet they're still available.

Z train Posted March 18, 2009 Share #9 Posted March 18, 2009 Well, what a revoltin' developement....I get the valve off and it is fine.I mean really free moving .Put it back in and let's go-right?Oh,no-this can't be that easy.The shaft that exits the heater box horizontally that attaches to the arm off the heater valve has a travel limit of less than a 1/4 inch.Something is jamming the door.So now the whole friggin box has to come out.(*^(&^%%*&!!!!!
