Delasangre4231 Posted January 23, 2010 Share Posted January 23, 2010 I'm about ready to replace my heater core and everyone seems to want me to change out all the hoses and some kind of control valve too. What are the specifics on these parts and where can I get them for cheap? Quote Link to comment Share on other sites More sharing options...

Delasangre4231 Posted January 25, 2010 Author Share Posted January 25, 2010 Ok but I don't know what parts are in there so which ones specifically are in need of replacement? Quote Link to comment Share on other sites More sharing options...

Delasangre4231 Posted January 25, 2010 Author Share Posted January 25, 2010 Ok, I see the hoses, but where is the vacuum control valve I should replace? Quote Link to comment Share on other sites More sharing options...
reddzx Posted January 26, 2010 Share Posted January 26, 2010 The hoses attach to the vacuum control valve +%5C%28Z31&cPath=2317_2318_2361_2379"] +%5C%28Z31&cPath=2317_2318_2361_2379"] Quote Link to comment Share on other sites More sharing options...
Delasangre4231 Posted January 26, 2010 Author Share Posted January 26, 2010 Ok great, stop being so vague. In the link you posted I see a ton of actuators, the picture is hard to make sense of. Quote Link to comment Share on other sites More sharing options...

Delasangre4231 Posted January 27, 2010 Author Share Posted January 27, 2010 Thank you. Now I will go look under my dash. Nice pic BTW for an under dash shot. Quote Link to comment Share on other sites More sharing options...
reddzx Posted January 27, 2010 Share Posted January 27, 2010 That's an under the hood shot. The heater is not visable under the dash with out removing the dash and the entire AC/ duct control unit. The control valve for the heater is vacuum operated and in near the passenger firewall in the engine compartment. Quote Link to comment Share on other sites More sharing options...
Delasangre4231 Posted January 27, 2010 Author Share Posted January 27, 2010 I swear someone told me there was something else under dash that usually leaks that should be replaced. While your in there, could you take a picture of where the hoses from the engine comartment go into the firewall. Mine are gone and I'm not sure if there is anything else right there.

Gregmatic Posted January 29, 2010 Share Posted January 29, 2010 If you haven't found a heater core yet I have a brand new one for sale at a very reasonable price (they are expensive). I also recommend replacing the hoses while you have it all apart. Quote Link to comment Share on other sites More sharing options...
Delasangre4231 Posted January 29, 2010 Author Share Posted January 29, 2010 I would like to take it, just give me a bit. I may be able to sell my other car, somebody just emailed me about it. I have to sell it before work begins on the 300zx... Quote Link to comment Share on other sites More sharing options...
