Removal Instructions
FACTORY MANIFOLD
7. In the fuse box, locate the tabs securing the five
wiring harness bundles to the bottom of the tray.
Release them with a fingertip or carefully using a
small flathead screwdriver or pick.
8. Release the tab on each connector. Slide it toward
the front or rear, and lift it out of the tray.
10. Locate the coolant reservoir near the oil sump tank.
Remove the bolt near the firewall securing the
coolant reservoir using a 10mm socket, extension,
and ratchet. Locate and remove the nut securing the
front bracket of the coolant reservoir, and free the
reservoir from the front stud. This will create more
clearance when removing the rear bolts on the
factory manifold and installing the CORSA
Performance Headers. Save bolt, nut, and bracket
for reinstallation (Install Step 19).
9. Once the connectors are removed, locate the three
nuts securing it to the frame rail. Remove the nuts
using a 10mm socket, extension, and ratchet. Save
the nuts for reinstallation (Install Step 20). Carefully
release the clamp for the AC line at the front of the
fuse box tray. Carefully remove the fuse box tray
from the vehicle. Save for Install Step 20.
11. Remove the spark plug wires and spark plugs from
both sides of the engine using a 5/8” spark plug
socket, 3” extension, and ratchet. Save for
reinstallation (Install Step 18). Remove the three
bolts securing the heat shield on the passenger side
factory manifold using a 10mm ratcheting wrench or
ratchet. Save heat shield if returning to stock. PRO
TIP: Remove the plastic fuel rail and coil pack covers
to create more clearance and make it easier to see.
Use a T40 Torx bit to remove the two bolts on each
cover. Disconnect vent lines as necessary.
12. Remove the bolts securing the factory manifolds to
the head using a 14mm socket and ratchet. Save if
returning to stock. PRO TIP: Do this now to reduce
the need to raise and lower the vehicle multiple
times while alternating between the engine bay and
underneath the vehicle.
13. Lift the vehicle roughly three (3) feet to have
sufficient space underneath to maneuver the headers
into place. PRO TIP: Use a hydraulic lift or hoist. A
jack and jack stands can be used if a lift is not
available.
