280z4me2 Posted February 12, 2009 Share Posted February 12, 2009 I have a 76 280z. I run it every other day for a few minutes because its not street worthy yet. Today I noticed radiater fluid on the driver floor. I found a black tube under the dash that it was coming from and put a napkin in it(you can see the napkin in the top right). After this, I noticed steam coming from the windshield defrost vents. Why is the coolant coming through the vents? Any ideas? Quote Link to comment Share on other sites More sharing options...
skib Posted February 12, 2009 Share Posted February 12, 2009 leaking heater core/heater core hoses Quote Link to comment Share on other sites More sharing options...
speedgato Posted February 13, 2009 Share Posted February 13, 2009 Yep, heater core. Quote Link to comment Share on other sites More sharing options...
280z4me2 Posted February 13, 2009 Author Share Posted February 13, 2009 I suppose there is a line running into the heater core. If I remove the heater core, will I have to block off the inlet hose? Quote Link to comment Share on other sites More sharing options...
skib Posted February 13, 2009 Share Posted February 13, 2009 you can loop it if thats what your asking, thats how im running mine while im still trying to get that damned heater box out (mine blew too) Quote Link to comment Share on other sites More sharing options...
280z4me2 Posted February 13, 2009 Author Share Posted February 13, 2009 Yes I will loop it. That will be the easiest. Curious though, why do you want to take it out if you arent using it? Or do you plan to use the heater? Quote Link to comment Share on other sites More sharing options...

Or do you plan to use the heater? i have it looped for now because i drive my Z every day and i need to take the heater box out to get to the heater core inside, here in OR you need your heat/defrost, it sucks with out it looping it is just a band-aid untill it can be fixed properly Quote Link to comment Share on other sites More sharing options...
Trevor Posted February 17, 2009 Share Posted February 17, 2009 I've been using one of these for a couple of winters in my DD. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=96144 Because the stock heater doesn't heat, It'll clear a frosty windshield, but doesn't heat the cabin much when it's below 40 F.

I bought one too and it doesn't do a good job. Like you said, just the windows really and if there is any ice. Mine barely blows warm air.
