Mount Bracket

The replacement process for Engine Mount and bracket starts with disconnecting the negative Battery Cable followed by removing the fuel injector sight shield then the Drive Belt. Prior to removal the technician will disconnect the electrical connector of intake air temperature (IAT) sensor and separate the air inlet duct from the Throttle Body. By disconnecting the right and left Engine Mount struts you should lift and support the vehicle from there. Start by removing the right front wheel and tire and then uninstall the right engine splash shield retainers along with its splash shield. The power steering oil cooler pipe brackets need to be detached from the frame before removing the A/C Compressor together with its mounting bracket which must be secured after completing the discharge process on the system. First remove the Catalytic Converter situated on the right side Exhaust Manifold then detach the Engine Mount lower nuts which fasten into the frame assembly. The installation of engine support fixture j 28467-b shall proceed after lowering the vehicle to lift the engine. Raising the vehicle enables workers to remove the left front Engine Mount bracket bolts and right rear Engine Mount bracket bolts that secure the engine. First secure the frame with jack stands afterward loosen the bolts on the left frame side before removing the right side bolts to lower the frame down for Engine Mount bracket removal. Complete the process by installing the Engine Mount to the Engine Mount bracket after removing the bracket and Engine Mount and the upper Engine Mount nuts. Fasten the Engine Mount upper nuts to 78 nm (58 ft. Lbs.) before installing the Engine Mount alongside bracket to the engine. Start with hand tightening the bracket bolts at the right rear and left front positions before finishing with bolt torque at 102 nm (75 ft. Lbs.). Put the frame in its normal position by using jack stands and apply torque of 180 nm (133 ft. Lbs.) to both right and left side frame bolts. Begin with a vehicle elevation then perform engine descent using the engine support fixture (J 28467-90A). Repeat the lifting process after which install the frame-side Engine Mount nuts and apply torque until reaching 78 nm at 58 ft. Lbs. Begin by installing the A/C Compressor bracket before adding bolts which need a torque of 50 nm (37 ft. Lbs.). Move on to install the A/C Compressor along with mounting nuts secured at 30 nm (22 ft. Lbs.). The power steering oil cooler pipe brackets should be reinstalled to the frame while the right engine splash shield and retainers along with the Catalytic Converter are positioned to the right side Exhaust Manifold. Finally place the proper front right tire along with its wheel onto the vehicle and lower it down while removing the support fixture for the engine and then reinstall the struts which support the engine before positioning the fuel injector sight shield in place and reestablish the negative Battery Cable connection. The general procedure ends with an air inlet duct installation to the Throttle Body and the connection of iat sensor electrical wiring followed by Drive Belt fitting and replacement of the fuel injector sight shield before reattaching the negative Battery Cable.

Remove the EVAP emissions canister purge valve and relieve the fuel pressure.

Finally, reinstall the engine coolant temperature (ECT) sensor and fill the cooling system.

Raise the engine to remove weight from the engine mount and create slight tension in the rubber.
