American Car Craft Camaro Valve Cover_Coil Pack Cover Set Polished ZL1 Only 2012-2013 - Manual (Page 2)

1. Remove the factory engine shroud. Take a while to look at the overall placement of all harnesses and hoses. You
will notice that all of these elements have been secured to their locations via factory plastic clips and retainers
that have been attached with electrical tape. Remove all fasteners and retainers completely from all harnesses
and hoses. This will allow you to reroute and rearrange these elements into a much tighter and out of view
placement. Detach and remove all the engines coil packs. As well as any other redundant bolts that may exist
on the valve covers. The packs are all the same so there will be no need to mark or number them.
2. You have been provided with 20 long zip ties to allow you to use your own judgment as needed to secure all
harnesses and hoses nice and tight to the fuel rail brackets and lines. Starting at the passenger side of the
engine. The main fuel line hopping over to the engine on the passenger side will need to be detached
temporarily. To do this you will need to use a line release tool available at any auto parts store and generally will
cost about a buck. You have been provided with a 3/8” rubber vacuum cap to cap the fuel line preventing fuel
from leaking out of the fuel rail. The line will have some residual pressure in it so have a paper towel around the
line as you release it to catch any overflow. This line will be reattached at the end of the wire tuck procedure
only instead of allowing the line to hop across to the engine you will reroute the fuel line towards the firewall
and then over to the engine. Your factory fuel line will allow you to do this very easily it will shape and it will
look like this was its original path.
3. You will notice a black plastic formed vacuum line. This is the fuel tanks vapor line and will need to be extended
in order to eliminate it from hopping over to the engine. You have been provided with a 48” length of 3/8”
vacuum hose. To install this hose simply detach the factory plastic hose at the two quick release ends and then
replace the line by simply pushing the new rubber hose in place. Since this is a vacuum line there will be no need
for clamps just makes sure the hose slips over the ridge at each end and the line will stay in place nice and
secure.
4. At this time you will see exactly just how you will be able to bind all of the wire harnesses for the fuel injectors
and coil packs nice and tight to the rails running alongside the engine. The main heavy harness present there is
the main engine harness. Route this heavy cable so that it can route around the right side of the engines oil fill
neck. Since the cable is relatively large you will need to man handle it a little in order for you to set it into just
the right position clearing the way for the new covers. Band all of these elements making sure that you have left
enough clearance for the factory engine shroud to snap back into place at the two ball studs provided for it.
5. You will notice that there will be two ground leads secured at the side of the engine head. One of these leads
(the smaller one) will need to be extended in order to be able to remove it from its original location and reroute
it over to the front end of the engine. You will notice an available bracket bolt at the forward end of the head.
You have been provided with a 10” length of #10-wire and a large yellow butt connector as well as a large ring
connector. Simply snip the factory ring connector off the end of this ground lead and extend it using these
simple crimp connectors. Make sure your crimps are very secure as to insure there will have no ground faults in
the future. You may elect to solder this extension for extra security. Once the ground lead has been successfully
extended simply route it forward loosen the available bolt set the cables end to that location and reinstall the
bolt and tighten securely.
6. The remaining ground lead is the main ground lead for the engine. This lead will be able to be relocated to the
heavy bolt location on the engine blocks side. There will be other ground connections already there so this will
