mark the plug wires before taking them off the plugs, remove all wiring and hoses out of your way, take a 3/8 ratchet and i think the bolts are a 10 mm. you probably need an extension on the ratchet, take the bolt out and if the pan won,t come loose hit the pan with a rubber hammer and take the pan off. clean the gasket surface on the pan and the head, install a new gasket. if it,s a cork gasket use a sealant on the gasket, install the pan and gasket, put the bolts back in and just snug the bolts, don,t tighten them too much or you will warp the pan, put the plug wires on.
