The ignition coil takes the power from the battery and converts it to a high voltage, then sends that electricity to the distributor where it is routed to each spark plug. On a 1987 Chevrolet Camaro with the V6 engine, there are two different types of ignition coils: internally mounted and externally mounted. To determine which one you have, see if a spark plug wire runs off of the distributor to a separate coil. If so, it's an externally mounted system.
Tools Used: Masking tape, Permanent marker, Phillips head screwdriver, 3/8-inch ratchet and socket, Open end wrench set, Remove Ignition Coil
Internally Mounted Coils
Use the masking tape and permanent market to label each spark plug wire and its corresponding contact point on the distributor. Make sure it's easy to read and figure out later on when you put the system back together.
Remove each spark plug boot from the distributor cap by grabbing the boots by the base and lifting them off the cap with a slight twisting motion.
Unscrew the distributor cap from the distributor using the Phillips head screwdriver and lift it off. Unscrew the ignition coil from the cap using the Phillips head screwdriver.
Externally Mounted Coil
Use the masking tape and permanent market to label each spark plug wire and its corresponding contact point on the distributor. Make sure it's easy to read and figure out later on when you put the system back together.
Disconnect the coil wire from the coil using your hands by gripping the boot of the wire and twisting it off from the coil. Then remove the remaining electrical connections using an open end wrench.
Unbolt the coil from the mounting bracket using the 3/8-inch ratchet and socket.
