Changing the Spark Plugs

NOTE:

!
It is recommended  that the engine  be cool
or cold  when changing  the spark plugs.  If
the engine  is hot, you  could burn yourself
on the insulated  connector, the spark plug
or the  engine itself.
Spark  plugs  should   be  tightened  firmly.
Over-tightening can damage the  threads in
the aluminum cylinder  head. Leaving them
too loose can cause the  spark plugs to get
very hot  and possibly  result in damage  to
the  engine.
You will find it easier to change spark plugs if the
engine is cold.  Always change one spark plug
at  a time.  This helps  avoid  getting the  wires
mixed up.
WARNING:
1.
2.
Remove  the  center  cover  on  the  engine
rocker  cover.
Using a clean cloth, remove any dirt that has
accumulated  around  the spark  plug  so  it
cannot fall into the cylinder  when the spark
plug is  removed.
To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core  conductor.
7.  Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has  snapped into place
and can't fall off.
4.
When  preparing to  remove  the  old  spark
plug, guide the socket down over the spark
plug, being  careful not  to damage  the ce-
ramic insulator.
To remove the spark  plug, turn the wrench
handle in  a counterclockwise direction.
To replace  the  new spark  plug, guide  the
socket  down  over  the  spark  plug,  being
careful not to damage the ceramic insulator.

Kathryn on Apr 27, 2015. I'm having nothing but trouble

I bought this used and the battery isn't completely dead but it won't start and my key won't work in the trunk to get to the spare tire, because I also have a flat.
