昨天挑灯夜战换99Montana Spark Plug。按照Hynes手册 Rotate engine,但还是不能卸下高压线的coil pack。根本摸不到更看不到手册所描述的后面两个螺栓。最后只换了前面3个。下周末准备钻到车底试一试。
作为一个工程师对 GM 的设计感到遗憾。不单单是Spark ...

it's a very tricky job.
u need a about 6" long extension and a 13mm socket.
try to touch 2 13mm nuts w/ ur left had and guide ur socket after.
**** some of those wires in the back are very hard to get loose from plugs. I usually use a vise grip and a pry bar to loosen wire by using mechanical advantage. Or you get wire loose and metal clip still on plug side. it means you need new wire set.
**** I recommend replace wire set as well, as they are not very expensive.
