How do you change spark plugs on a 1996 caprice classic?

Answer 1

To change spark plugs on 4.3 engine for 1996 caprice-the first three are easy on driver's side and can be done from top of engine using standard tools including elbow tool. The last one toward engine firewall on driver's side is done from underneath with relative ease using same tools.

Passenger side first three from firewall are easy but the last one at front by a/c and alternator is tough. Here is what I did-disconnect and bend the pollution pipe that hides the spark plug-move it toward back of engine till you can place your spark tool in there using a 4" extension piece and elbow. You must hold the elbow steady at a slight angle so it will not twist making it impossible to loosen the plug.

My engine ran much better after changing these two difficult plugs which had been ommitted by former tuneups because it takes work and that includes removing a/c and or alternator.
