Mazda CX-5 Service & Repair Manual: Engine Removal/Installation

WARNING:

• A hot engine can cause severe burns. Turn off the engine and wait until it is cool before servicing.

• Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.

• Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”..

CAUTION:

• Secure the steering wheel using tape or a cable to prevent the steering shaft from rotating after disconnecting the steering shaft. If the steering wheel rotates after the steering shaft and the steering gear and linkage are disconnected, the internal parts of the clock spring could be damaged.

• Applying excessive force (force of 100 N {10.2 kgf, 22.5 lbf} or more) to the electric variable valve timing motor/driver may cause a malfunction. When servicing, be careful not to apply excessive force to the electric variable valve timing motor/driver using other parts or tools.

Engine Mount Installation Note

CAUTION:

• Slots have been adopted for the No.3 engine mount and No.4 engine mount bracket installation holes. Tighten the installation bolts and nuts so that they are centered on the slots. Otherwise, engine noise or vibration could increase.

NOTE:

• Retighten the stud bolts of the No.3 engine mount bracket and transaxle when the nuts of No.3 engine mount and No.4 engine mount bracket are loosened.

1. Tighten the No.3 engine mount stud bolts.

Tightening torque

• 7—13 N·m {72—132 kgf·cm, 62—115 in·lbf}

2. Tighten the stud bolts for the transaxle.

Tightening torque

• 15—25 N·m {1.6—2.5 kgf·m, 12—18 ft·lbf}

CAUTION:

• When supporting the engine and transaxle, insert rubber of appropriate size (approx. 20 mm {0.79 in} thickness) between the engine lifter and the oil pan, transaxle to prevent the deformation of the oil pan and damage of the transaxle.

3. Secure the engine and transaxle using a commercially available engine lifter.

4. Temporarily tighten the No.3 engine mount installation bolts and nuts using the following procedure:

a. Temporarily tighten the bolts shown in the figure so that they are centered on the No.3 engine mount slots.

b. Temporarily tighten the nuts shown in the figure so that they are centered on the No.3 engine mount slots.

NOTE:

• If the stud bolts are deviated from the center of the slot, align the stud bolts with the center of the slot while slightly moving the engine, and temporarily tighten the installation nuts.

5. Temporarily tighten the No.4 engine mount bracket installation bolt and nuts using the following procedure:

a. Temporarily tighten the bolt shown in the figure.

b. Temporarily tighten the nuts shown in the figure so that they are centered on the No.4 engine mount bracket slots.

NOTE:

• If the stud bolts are deviated from the center of the slot, align the stud bolts with the center of the slot while slightly moving the transaxle, and temporarily tighten the installation nuts.
