How do I change the rear 3 spark plugs and wires on a my 2001 Silhouette 3.4?
Answer: Well there are 2 ways to get to those. Either way is not easy. The plug wires are very difficult to get off. Need to turn the wire on the plug to break the wire loose. You can get them from the top while laying on the engine using a universal/swivel plug socket on an extension.
Some Tech's. Unbolt the two upper engine mount struts and pull the engine forward, then hold it in place with a special holding tool. I always do it from under the van. Still, very difficult. The front one you can get to through the wheel well, the other two from putting your arms up along the exhaust pipe. Dropping the exhaust pipe from the manifold helps. You can also gain some room by removing the 2 rear frame bolts while SUPPORTING the frame with a screw jack.
BE VERY CAREFUL! If you lower the frame too much (more than 4-6 in.) the steering shaft can become disconnected from steering column and cause all kinds of grief. Either way, is difficult even with universal/swivel socket. Your arms will get stuck here and there and maybe cut up too.
