Installing the engine assembly (Mazda CX-5KE)

Caution: If the position of engine support No.3 is different from the original position when reinstalling, this will result in increased engine noise and vibration. Before removing engine support No.3, apply alignment marks to engine support No.3 so that the support can be installed in the same position later.

Note: If the engine mounting support #3 fastening nuts are loose, the engine front cover threaded studs must be tightened as they may be loose rather than the nuts.

1. Tighten the threaded studs of the front engine cover to a torque of 40-52 Nm.



2. Tighten the gearbox threaded studs to a torque of 15-25 Nm.

3. Proceeding in reverse order, place the power unit under the engine compartment of the vehicle, and then lower the vehicle onto the lift.
