Well today i was puttin my dual pass endplate with option b. Everything was going great until it came time to bleed out the air... Went to loosen the bleeder on the stock heat exchanger when the cap just fell off. I mean i didnt even give it a 1/8 of a turn... So i called up my buddy that works at the dealer and he said he would see what he can do... I mean what an f'ed up night....
