biohazard53188 Posted December 22, 2006 Share Posted December 22, 2006 Now i know im going to sound like a noob but I searched all over the site and couldnt find anything. My question is, what is the purpose of those little vents beheind the windows on first gen z's. Ive heard a bunch of things that sound kind of rediculious and i just want to clear it up.

spotfitz Posted December 22, 2006 Share Posted December 22, 2006 Releasing cabin pressure. early 1st gens had the vents in the hatch. Quote Link to comment Share on other sites More sharing options...
Bartman Posted December 22, 2006 Share Posted December 22, 2006 Yes, they release cabin pressure. I had read a detailed explanation of the Z ventilation system previously, but I don't know where. The Z flow-through ventilation was one of the Z's features. It's a complete system with fresh air entering in the footwells and exiting the rear vents that have some type of flap to prevent backdraft. I think the system was detailed in some of their sales literature. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 22, 2006 Share Posted December 22, 2006 In truth those flaps on the hatch vents don't work so hot and its more of a carbon monoxide induction system... Quote Link to comment Share on other sites More sharing options...
alexideways Posted December 22, 2006 Share Posted December 22, 2006 Will it make a discernable difference in comfort if I patch them? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 22, 2006 Share Posted December 22, 2006 I did patch mine with some scrap metal and a bunch of silicone, and for a long time I had no exhaust smell at all. Eventually my hatch seal gave up and then it was pretty bad. Quote Link to comment Share on other sites More sharing options...
Dtsnlvrs Posted December 22, 2006 Share Posted December 22, 2006 The hatch vents did indeed allow for the "flow thru" vent system. If you patch them over, then the vent sys will not work properly. Try this, for thos eof you who have patched them over, roll up your windows and set the sys for fresh vent but do not turn the fan on. You will see that there is very little air flow, now slightly crack the windows and you will see a much greater increase in airflow...this is why they had the vents. Now, as far as the fumes go, there is a flapper valve in the hatch panel, and after years of use and abuse, it does not seal properly. To remedy this, remove the panel and disassemble the flapper, taking care to not lose anything. Now soak the rubber flaps in silicone spray, don't ask me how to get it out of the can without making a mess. Soak them for at least a week, then reassemble and voila..no more fumes (assuming the rest os the seals are good) 1 Quote Link to comment Share on other sites More sharing options...
