Spark plug replacement - 1998 GMC Envoy

Things you will need
Spark Plug Socket And Wrench of the correct size for your spark plugs


Basic Instructions.
Step 1
Locate your spark plugs
look for other obstructions besides your spark plug wires
if you have any other obstructions you will need to remove them as well to gain access to your spark plugs.
Step 2
Remove the spark plug wire for one single spark plug at a time.
this will insure you will not replace the wrond spark plug wire to the incorrect spark plug,
if not done this way you could change the firing order of your engine.
Step 3
With your spark plug Socket and wrench rotate the spark plug in a counter clock wise direction for removing.
Step 4
After you have removed your spark plug insert your new replacement spark Plug into your spark plug socket before inserting it into the correct location. spark plug sockets are made to hold on to the spark plug for easy removal and install.
Step 5
insert your new spark plug,
before you rotate your spark plug for tightening rotate the spark plug a 1 quarter turn in the counter clock wise direction, then start tightening the spark plug by rotating it in a clockwise direction
This will insure you will not strip the threads.
Step 6
Continue rotation your spark plug in the clock wise direction untill snug, then with just a lil more pressure tighten it up just a little more.
be sure to not put to much force on the spark plug after it has been snug, you just have to apply a little more pressure but not to much that could cause it to break.
Step 7
After tightening the spark plug replace the correct spark plug wire.
then move on to the next spark plug and follow the same instructions.

if you have any other visiable obstructions preventing you access for replacing your spark plugs you will need instructions on how to remove them parts. i have just instructed you on how to remove and reinstall the spark plugs only.
