Alright, i've been on the phone with some of Nissan dealers for the last 2 hours :lol: , friday thing, dont' feel like working lol. Anyway, no one was able to find the article for the vent EVEN THOUGH it shown on their pdf sheet that there is a square HOLE on the bonnet!!!!
To be able to dig in further, i'll need a chassic number of an R34GTR. Well its' not that important, i'm just curious thats all. Garry Roger Nissan has been very helpfull, Also found part number for R32GTR Thermal switch (2159573L05) and cost $115+gst still they don't know what temp range it will activate the fan.
