How do you change spark plugs?

If you are just going to change the spark plugs on the 3.4 then the rough part will be the rear plugs as you have to get the van on a set of ramps and let the motor cool off so you won't tear the threads out of the head when the plug comes out. I like to blow compressed air around the plugs to bloww any dirt or debri that could fall into the plug hole as the sparkplug comes out. The front plugs are easy to change. Twist the plug wire and pull it off the plug use a 5/8" sparkplug socket and find an exstention that will let you loosen the plug without hit your knuckles first of all then hitting anything else. Loosen the plug with the ratchet after loose then use the exstention to tun the plug out. Check the gap on new plug to make sure it is correct. Then put just a little antiseize on the plug threads before you put them in don't tighten them any tighter than it took to loosen them. Now to get to the rear ones you have to run your arm up beside the exhaust pipe to the plugs and do them one at a time so you won't mix up the wires. The rear plugs are tough as there is not much room to work. But if your patient and aren't prone to aggitation too much then you can change the plugs on this motor. Good luck
