So there i was 1st thing this morning, out on my car... I cut a hole in the lower spoiler and mounted my Oil cooler.... i routed the braided hoses underneath and around to the oil filter. I jacked the car up, took the sump plug out.. let the oil drain out. undid the oil filter, drianed out the oil in that.. put the sump plug back in.. The i got the oil cooler adaptor that goes in between the oil filter and the engine block... Yeap you`ve guessed it.. slightly different thread !! Who would of thought that a 1.6 GTI block was slightly different to a 1.9...? So I`ve taken it all off again.. but some nasty looking mesh over the whole ( will tidy later ) and took it all off and put the car back to how it was ggggggggrrrrrrrrrrhhhhhhhhhhh So I`ve now got an almost mint Oil cooler for a 1.9 GTI if anyone is interested !! LOL....
