I just want to know if there is a trick to getting to the driver side rear spark plug, looks like it is going to be fun. Also what else needs changed when I do a tune up?

if you don t see any spark plug wires then your motor has coil packs(black colored boxwith 2 small electrical wires) located on top of motor 3 on one side,3 on the other.disconnect negative terminal on battery,then disconnect wire connector at each coil pack and remove 2 screws that hold down coil pack, pull gently straight up and plug is right there below coil pack

you need to put a ratchet ******** the front of the engine and remove the dog bone engine mount this will allow the engine to be pulled forward with strap and you can reach behind and remove the plugs or you can get them from underneath the van hand tightened with a spark plug socket and wrench if you overtighten they will break

look under hood..you will see wires coming from distributor cap on top into your motor..if its an 8 cylinder there will be 4 in the back and 4 in the front.6 cylinder-3 in front 3 in back.get a 5/16 spark plug wrench and socket.you will need extension to reach back ones.if you bought new wires from parts store it will be even easier to find where plugs are located because you can compare the ones you bought and easier find the wires under the hood.the wire gets fatter as it goes into the motor.grab the fat part firmly and pull it off.boom theres your spark plugs.use your spark plug socket(5/16) with extension/ratchet and turn the plug until it comes out.do not break the plug or it will not come out.when you put a new one in screw it hand tight then 1 crank tight with the ratchet.when you change your wires do them one at a time as to avoid switching the wires up.on top of the distributor cap(where the wires lead to) there will be numbers as to what wire is for what cylinder...change plugs/wires 1 at a time dont take off more than 1 wire at a time!hope this helped!

There are tow ways to get to the plugs, You can get to them from the top or from the bottom. There's quite a bit a bit of room in the transmission tunnel, and you can reach up and actually touch the plugs. There is trouble with the "alternator plug" (#1) , Hard to reach it from below, and you may ended up removing the alternator bracket and shoving the alternator back.
From the top end, removed the windshield wipers/cowl assembly, the intake plenum, remove the bracket from the alternator, easy, and the hardest part is just removing the bracket holding a wire harness from the back of the plenum, the bolts are a little hard to get to due to the a/c lines, but after they were out the plenum removed with ease and I replaced the back plugs(with champion double platinum RN14PMP5 OEM's) and replace the spark plug wires with BWD Selects. They are very good wires. Used anti-seize of course. Mounted the wire harness bracket back, put the plenum(with new gasket), vacuum lines, sensors, and alt.bracket back on then changed out the front ones. Replaced Wipers and your good to go.
Note: if from the bottom rotate the alternator to get the pass side and from below to get the middle and drivers side. You can use a jack stands and a creeper. Takes about an hour. Yes it's a PITA but, going from below greatly reduces the chance of spinning a bolt head off or breaking something else in the process of getting to the plugs. No special tools needed.
Good luck and if your lazy like i am just change the front ones and have a local shop replace the rear, they have the lift and will only cost an hour shop rate in your area. $65.00/hour average.
