Comments about ACDelco Ignition Coil:

Looks to be a drop in replacement for the original coil. Does require you to drill out or otherwise remove the original rivets so you can re-use the factory bracket. Not difficult, but does take some extra skill and ability. The replacement unit bolts in with supplied bolts. Otherwise, easy to replace on a GM4.3, the coil is readily accessible on the top of the motor.

      The original parts is attached with rivets. They will have to be drilled out. The new part comes with screws, smart!

            I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

            A:

            The ignition coil is built into the distributor. The ignition signal from the ECM is sent to the power transistor. The distributor is not repairable and must be replaced as an assembly except for the distributor cap and rotor head. The rotor screw which secures distributor rotor head to the distributor shaft must be torque properly.

            be sure you are replacing the coil for the right reason. LOOK closer!!! the wires connecting might just be broken. due to intake gasket replacement/ over handling!!!!! look first

          • A:

            You will need to file or carefully grind the tops off of those rivets on one side and drive them out of the bracket with a punch and a hammer or if you don't have a punch use a nail with the point filed flat. Reassemble using the supplied small machine bolts.
