How do you access the spark plugs on a 1996 Oldsmobile Achieva?
Remove the four bolts on the cover plate and lift straight up exposing the wiresets.
to change the spark plugs...they have a special tool you by and you pull the wires off then you stick the tool down inside and you unscrew them and the install the others! on this vehicle you have to remove the coil pack on the back of the engine to get to the rear plugs to do this take the four bolts off the coil pack and simply move it out of the way to…
remove the pretty plastic on the top of the motor once remove you will have direct access to the front 3 spark plugs, to remove the rear spark plugs remove the intake manifold and then you will be able to access the back bank of spark plugs. then reassemble everything. tools needed ratchet and sockets and large extension
Disconnect the battery, remove the air hose to the throttle body, remove the access plate, remove the spark plug cables and the boots, and remove the spark plugs. Replace the spark plugs, replace the boots and cables, replace the access plate, attach the air hose to the throttle body and connect the battery.
The 2002 General Motors/Oldsmobile Intrigue came standard equipment with the 3.5L V6. This vehicle is a front wheel drive application with a transverse mounted engine. The sparks plugs are in the cylinder heads, with plugs facing the front and the other three facing the firewall. The OEM AC Delco Professional Iridium spark plugs are part #41993.
The spark plugs are located under what is called the "ignition module cassette". These cassettes are the silver assemblies on the top of each valve cover. Remove the cassette, and the spark plugs are under and down into the valve cover. Will need an extension on a ratchet and socket to reach them.- techJK ------------------------------------------------------
