How do you change spark plugs on a Pontiac Trans Sport?

Answer 1

I haven't got to the back row of sparks plugs yet, however make sue you have either a swivel extention(I used a 3/8 Drive Universal Joint) or something shorter than 6 inches for your rachet. I tried removing the spark plug and with the extention on I kept hitting the AC tubing going across the front... I am going to start on the back row and was told by a friend to undo that motor mount in front and then while in park move the car forward a little and place a brick or wheel chock behind the tire. By doing this the motor will tilt downwards and towards the front giving you just a little more room to get to the back three wires and plugs.. . hope this helps and hoepfully I can get this done with out having to call the mobile mechanic!

Partial AnswerOf couse, the front plugs are no problem. The problem seems to be in the back 3. I have found online and from some mechanics, that you need to undo the motor mounts and rotate the engine. I have never tried that, and have replaced the back 3 going on two times now. First and foremost, you REALLY need to let the engine completely cool down. Your hand and arm are going to be touching extremly hot surfaces. I have a medium size hand, and i say that, because i don't know if that helps me, or if anyone's hand will fit. You can reach the back three with the van jacked up, and patience. It will take some time to manuver the plugs in and out. However, it is possible. Trust me, i have done it. GOOD LUCK!

Going by what I have read, the book says to remove the fender. I did it myself laying on the engine and going by feel. It was a real bear but I did not have to undo the motor mounts, fender, anything, but I was sore for a couple days.
