INSTALLATION INSTRUCTIONS

Please study these instructions carefully before installing your new Coil Covers. If you have any questions, do not hesitate to contact

our Technical Hotline at: (800) 416-8628 from 7:00 am to 5:00 pm, Monday through Friday, Pacific Standard Time.

DESCRIPTION: Edelbrock Coil Covers are designed to enhance the appearance of your GM Gen III engine by tucking the wiring

harness beneath attractive polished or as cast aluminum covers. These covers will mount to any Gen III LS series motors with stock

center bolt style valve covers equipped with stock Delphi coils (GM PN 12558948). These covers are intended for use on street rod

or custom applications and as such, may fail to clear some hose routings found on stock vehicles.

INSTALLATION INSTRUCTIONS:

Note: These covers are intended for custom hot rod applications. As such, they may not clear all the hoses, emission hardware,

and/or accessories found in a stock application. Modification of the covers may be necessary for use in such an application.

1. Disconnect and remove the spark plug wires and set them aside for reinstallation later, then detach the wiring harness connector.

Unbolt and remove the bracket with the coils attached. At this time, test fit the coil covers on the engine to ensure they will fit

your application without interference.

2. Once the fit has been verified, separate the wiring loom enough to disconnect the small clips securing it to the bracket, then

remove the individual coils from the bracket. The stock coil mounting bracket can be set aside or discarded as it will not be

reused. Mount the ignition coils to the underside of the covers using the stock bolts, carefully routing the wires so as to prevent

them from being pinched or damaged.

3. Attach the supplied reusable tie wrap to the center provision on the underside of the coil cover using the supplied #6 cap screw.

Use the tie wrap to secure the wiring harness connector to the cover, then install the spark plug wires onto the ignition coils.

The coil cover can then be secured by threading the supplied bolts into the mounting holes of the valve cover. Use a dummy

bolt secured with a nut to fill any mounting holes in the coil cover that do not correspond with a threaded boss in the valve cover.

4. Attach the ignition wires to the spark plugs and your installation is complete. Installation is the same for both sides of the engine,

but be aware that the engine oil dipstick tube may need to be bent outward slightly to clear the passenger side cover.
