and remove the throttle body from the vehicle slowly ensuring that no other connectors are hindering removal. Discard the four factory mounting bolts.

5. Remove the seven torx head screws from the water crossover manifold on the bottom of the stock throttle body. Clean all gasket surfaces and transfer the IAC motor housing to the new throttle body using the supplied gasket and screws - be sure the housing is fully seated to the throttle body to avoid any leaks.

8. Re-install the negative battery terminal, refill the coolant tank to allow for lost coolant and start vehicle. Idle adjustments are made on set screw accessible from the back side of throttle body on driver’s side of vehicle.
