How do you change spark plugs on a 91 e 350 ford van?

Answer 1

I have a 92 Ford 350 Motorhome. I needed to do a tuneup on it and searched for info on changing plugs and fond nothing. I did it my self and found a way. On the left bank cylinders 2,3,4 are not much problem but #1 cylinder is nearly impossible. I finally removed the battery and aircleaner. Their is a bracket that holds the air intake flex/solid tubing. Remove it. Their are 2 bolts next to the radiator that are hard to get to but it can be done with a small end wrench. You now have enough room to reach #1 plug with a swivel socket and extensions. I actually had more trouble with the #5 cylinder First one on left bank. I removed the battery (RV battery) making a path for extensions and swivel socket. I broke the plug getting it out and had problems getting the new plug in. I used a spark plug wrench with a rubber insert to hold the plug. The problem was it could not be removed because of the boot friction. I finally put the plug in with a spring loaded "getters". I laid it in the heat shield under the plug and then removed the rubber boot from the plug socket. I then could degotiate the socket down and thread the plug in and when it was tight i could pull the socket off without much problem.

Just hope I never have to do this again. Hope this helps.
