djsri hiya how easy are the spark plugs to change? i took the cover off them and noticed they have coil packs?? on each lead on the plugs..how do i remove without damaging etc...any1 know what best plug and also size of the socket..cheers
blue_se2 16mm deep socket and best plugs to use are genuine Gm You have to remove the coil pack 4x 10mm nuts then simply remove the plugs and replace with the new ones be care full not to drop the new plugs as they are gapped already and don't over tighten them!!!
baldie87 just a case of unboloting and and removing coil pack then removing plugs, be very careful not to over tighten as you can crack the head as for which spark plug alot of people use genuine vauxh plugs or ngk ones but do not buy champion
