The following steps need to be performed from underneath
the vehicle:
• Remove the three 7 mm screws holding the front fascia
inside the radiator opening.
• Next, remove the 7 mm screws on either side (one on each
side). These are the screws holding the bottom of the
bumper cover - see picture.
Remove the two plastic push lock plastic fasteners holding the
radiator shroud to the bumper beam. Remove the two plastic
Christmas tree fasteners from each side of the radiator shroud.
Guide the side wings of the radiator shroud around the lower brackets. Remove the shroud from the top side,
pushing condenser rearward as necessary for clearance. If the shroud does not clear the bumper during removal,
it may be easier to free it from the under side of the vehicle.
NOTE: If you do not feel comfortable with performing the
modifications to your shroud that are listed in the following
steps or you would prefer to keep the existing shroud in stock
form, LPE offers an already modified production GM shroud.
Contact LPE or your LPE distributor.
Cut out the template, cutting along the outer short dashed
line only. Thoroughly clean the shroud to ensure adhesion of
tape for the next step. Place the cut template on the shroud as
shown, ensuring the line on the template matches up with the
crease on the shroud.
Secure the template in several places with tape. Use a center punch to mark the centers of the holes to be
drilled. You should have 19 center punch marks. It is important to make sure you do not remove the template
until all 19 holes are marked.
• Remove template.
• Drill four 5/16” holes first as shown on template.
• Drill seven 11/32” holes as shown on template.
• Drill eight 1/2” holes as shown on template.
• Using a ruler & marking tool, connect outer edges of
1/2” holes to form cut line as shown by “dashed lines” on
template.
•
Using saw or other suitable cutting tool cut on line drawn,
making sure to NOT CUT OUTSIDE OF LINE.
Reinstall modified radiator shroud.
From underneath, reinstall the two push lock fasteners that secure the shroud to the bumper beam.
From the top side, install the two factory “Christmas tree”
fasteners holding the radiator shroud to the condenser.
Remove two plastic pins from the top mount radiator shroud
by prying up center nail, then pulling out (as shown in image).
Install the two supplied “Christmas tree” fasteners into same
holes that held the two plastic pins.
