Thanks ever1 for the replys I thought jimmer was closest as heard a look about him on this forums still quite a mission for me. Iam lucky my brother is a mercanic but think his sick of the z already As i his already done cambelt and service new rad and fan.does any1 have any advice on the vicus fan I changed mine as it was cracked to an electric went out yestaday and had coolent leaking from the bck of engine wen I parked up temp gauge was about halfway I no there useless my question is am I better putting the original fan bck on as I not sure if it's getting to hot just ordered a aftermarket temp gauge so hopefully that give me a better idea cheers scott
