How to change spark plugs and wires?

I have a 2002 Chrysler town %26amp; country Limited with 105K miles on it. Due to very low mileage (12 mpg), I need to change the spark plugs (and possibly wires). I will appreciate if anybody could provide me instructions (Do's and Dont's) so that I can do it on my own. ThanksHow to change spark plugs and wires?Make sure you mark the position of each wire. Make sure you have the proper spark plug socket (with a rubber insert in it to protect the plug) Don't over tighten the new plug when installing them. There is not much more.How to change spark plugs and wires?I just changed the plugs on our 2002 town and country. All the sites I saw said that you had to remove a bunch of stuff to get at the rear plugs. I was able to reach back there and get at them. I had to use extensions of various lengths with my sockets, but I was able to get at them. Took 1 hour.

How to change spark plugs and wires?well you should easily be able to locate your spark plug wires and that would be the easiest thing -

one end will be where you place plugs into the engine the other end will be your distributor cap - as you take out plugs from your dist cap make sure you number them with tape ( masking tape ) this is your fireing order and you do not want to mess this up -



buy the pregapped plugs if your not familiar with changing them this way you dont have to worry about the gaping tool - i cant stand them personally -



and basically all you have to do is unplugg from each end replace your plug and wires -



since you arent getting good milage consider replaceing your air filter also -How to change spark plugs and wires?View the Advance Auto online %26quot;todays tuneups%26quot; video for the basic spark plug and wire installation

http://www.advanceautoparts.com/english/How to change spark plugs and wires?go to the parts store, pick up a haynes maintenance manual, how many cylinders does your engine have, pick up that many spark plugs, and wires, rent or buy a torque wrench, a distributer cap and rotor and an airfilter. mark everything where you find it. if you want to save a bit of money, skip the manual (they are handy to have for other maintenance stuff, though) and get everything else. You can get the torque values from the internet and the firing order should be stamped on the engine block, also the cylinder numbers should also be stamped on the block. Before you remove the wires, mark them the same as the cylinder numbers from which you removed them. leave them attatched to the distributer cap!!!! But make sure you mark them to match the cylinder mark on the block!! Then remove and replace the plugs, use the torque values. . . check each plug as they come out. there should be a nice uniform greyish white burnt look to them. note where the ones that look different came from and use the internet to find out what could have caused any irregular deposits on them. Then one by one replace the wires, making sure that you plug them all up to the same reciever on the distributer cap from which you removed them ONE AT A TIME!!! , them, remove the distributer cap, and line it up with the old one and trade the wires over to the new one, one by one, making sure that they are all in the SAME place they were on the old one, set aside, replace the rotor, you just pull it out and put the new one in, in the same position you found the old one in. then you reattatch the distributer cap and you should be on your way with MUCH better gas mileage!! Oh!! also replace your airfilter. . . umm you might also replace your fuel filter as well, sometimes it gets clogged up and messes with you mileage. . .? Good luck and I hope I helped some!! ^_^
