How do you change spark plugs on a 1998 pontiac Grand Prix?

Looking at the engine they are in a line next to the engine, All six of them. reading something said there are three in front in three in back, so im not sure if what im looking at is correct. Help?How do you change spark plugs on a 1998 pontiac Grand Prix?ok first of all bunch of dummies telling u things that aint right. first of all it should be done at 100,000 miles so if u have over that many mile its likely it has been done already. next it is a V-6 motor, 3 plugs up fromt and 3 in the back. first step is to make sure ur engine is completly cooled down due to the fact it has alunimum heads. next step is to do one at a time. start with either side of the front of the motor. gentle pull one plug wire at a time. the tools u need is going to be 3/8drive rachet, 6in extension and 9/16 deep socket for the front and same for the back except the ones on the back are tricky. when u remove ur plug wire slip ur socket over the plug an dloosen it up, it might be tight if there are oringinal plugs, dont worry, little tug and they will come loose. next step is to get ur new plug and smear some thread antiseize on the threads, next make sure u double check ur gap on ur plugs, they are set at the factory but they do bounce around so double check that. next stick the new plug into the socket and lower to the plug hole, make sure u dont bang it around that will knock ur gap off, thread it in with the socket and extension, finger tight at first so u wont cross thread it. next just tighten it down with ur ratchet, not too tight though. the rest do the same. the back is harder but the same way. the best way is to put it up on car ramps and do it from underneth.How do you change spark plugs on a 1998 pontiac Grand Prix?One at a time! lol no really.your spark plugs have a spark plug wire goung to the top of it.hold the wire at the spark plug firmly and pull it off the sparkplug use a wratchet and a deepsocket and unscrew the sparkplug(righty-tighty,lefty-loosey)rep?with the new one make sure to get it tight and push the wire back on,push it real hard to make sure it is all the way down. do one at a time so you dont get the wires mixed up.How do you change spark plugs on a 1998 pontiac Grand Prix?the answer to ur original question is 1 at a time--lol

you are probably looking at the coil pack located on the side of the motor.

with closer inspection of ur engine you should locate them--the other end of the wires on the coil pack.

to change the ones in back it may be necessary to remove the alternator n reach in blind.

i am serious about changing them 1 at a time, this avoids improper spark timing. glHow do you change spark plugs on a 1998 pontiac Grand Prix?When doing the back ones, you might have to %26quot;roll%26quot; the motor forward to give you more room. This is done by removing the 2 motor mounts on the front of the motor that bolt to the brackets on the radiator core support. There is 2 bolt through each bracket. Best to use a racheting strap to hold motor in place and to pull forward. The back 2 on the right are the worst because they are so close to each other.
