Installation Instructions
Warning:
•
Let the engine cool for at least 6 hours before
opening the cooling system to avoid burn injury.
•
Always use jack stands to support the weight
of the vehicle. Never rely on jack alone.
•
Make sure to dispose of old coolant properly at
a recycling facility.
Removal:
1) Chock the rear wheels, jack up the front of the vehicle
and safely support on jack stands. Ensure engine is
cold. Drain the cooling system then reinstall the drain
plug. (You may need to remove the factory plastic
splash guard (if equipped) to access the radiator drain
plug.)
2) Remove the clamp retaining the hose to the Idle
Air Control valve. Remove the IAC hose and PCV
breather hose at the air tube. Loosen the screws
retaining the air intake tube to the throttle body and
air filter box. Remove the air intake tube.

3) Remove the two 10mm bolts retaining the metal

temperature sensor (temp gauge) located on the
driver’s side back of the cylinder head, underneath
the camshaft position sensor.

5) Remove the three 12mm bolts retaining the coil
bracket to the back of the valve cover. You can
leave the spark plug wires and electrical connectors
connected to ease reassembly if desired. Carefully
lift the coil bracket up and place on top of the
valve cover, being careful not to damage the coil
connectors.
Note: If you choose to remove the
electrical connectors at the coil be sure to mark
them, as they can be easily reversed and installed
in the wrong coil causing a no start.
