if your stunting a 03/04 636 ull know that the rads are crap, keep braking lugs, leaking, and a bitch for over heating etc.. i couldnt get a second hand 1 anywhere and there 410 plus vat new so **** that... solution? honda blackbird rad...i bought the rad and fan for 120 euros and it bolts on easy enough, just 2 40mm spacers to make up and its 2 rows longer so she'll cool abit better and the fan spins faster, just wire the fan direct to a switch and away you go..
