I have a 1993 Full size blazer. I am going to tackle the job of installing new spark plugs and was curious what the steps in doing this job is and what tools I will need? Please help!!!

 

take one boot off at a time to make sure you get it back on the right plug, you will need a spark plug socket, ratchet and extension a universal joint will help get into the tighter areas. a spark plug wire pliers helps but is not needed

 

be sure to gap the plugs at .035"
