WARNING:

• Situate the vehicle on a flat and solid surface.

• Place chocks at front and back of rear wheels.

• For engines not equipped with engine slingers, attach proper slingers and bolts described in PARTS CATALOG.

CAUTION:

• Always work safely.

• Do not start work until the engine and exhaust system are cooled completely.

• Refer to the applicable sections for warnings, cautions, notes, and instructions if necessary procedures are not included in the engine section.

• For supporting, lifting and jacking points, refer to Garage Jack and Safety Stand and 2-Pole Lift.

• Always use the support point specified for lifting.

• Support the Nissan Murano vehicle at the rear axle jacking point with transmission jack or similar tool before removing the engine in preparation for the backward shift of the center of gravity.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

REMOVAL

Outline

Remove the engine room cover. Refer to Removal and Installation.

Remove coolant reservoir.

Drain the power steering fluid. Refer to Draining and Refilling.

Disconnect engine room harness at the CVT and ECM connectors.

CAUTION:

Protect the harness connector with plastic bags or suitable covering to help prevent damage and intrusion of foreign materials into the connectors.

Remove the battery tray. Refer to Removal and Installation.

Disconnect heater hoses (engine side). Refer to Removal and Installation.

Remove upper and lower radiator hoses. Refer to Exploded View.

Remove high pressure pipe, low pressure pipe, high pressure flexible hose, and low pressure flexible hose. Refer to Exploded View.

Remove EVAP hose.

Disconnect fuel feed hose quick connector at fuel tube side. Refer to Exploded View.

Disconnect CVT control cable. Refer to Exploded View.

Disconnect brake booster vacuum hose at brake booster. Refer to Exploded View.

Remove harness ground cable.

Disconnect low pressure hose from steering pump. Refer to Removal and Installation.

Disconnect high pressure piping from steering pump. Refer to Removal and Installation.

Disconnect the wiring harness from the distribution/fuse block.

Disconnect the CVT fluid cooler hoses from the CVT.

Remove the upper RH upper torque rod.

Remove engine mounting insulator (RH) three upper nuts.

Vehicle Underbody

Remove exhaust front tube. Refer to Exploded View.

Remove rear propeller shaft. Refer to Removal and Installation.

Disconnect steering lower joint at power steering gear assembly and release steering lower shaft. Refer to Exploded View.

Disconnect front stabilizer connecting rod. Refer to Exploded View.

Remove front brake caliper assembles with piping connected and position them aside. Refer to Removal and Installation.

Remove rear plate cover from oil pan (upper). Then remove nuts attaching the drive plate to the torque converter. Refer to Dowel Pin Alignment.

Remove crankshaft position sensor (POS). Refer to Exploded View.

CAUTION:

• Handle carefully to avoid dropping and shocks.

• Do not disassemble.

• Do not allow metal powder to adhere to magnetic part at sensor tip.

• Do not place sensors in a location where they are exposed to magnetism.

Removal

Use suitable tool to securely support bottom of front suspension member.

CAUTION:

Put a piece of wood or something similar as the supporting surface to secure a completely stable condition.

Remove front suspension member mounting nuts and bolts. Refer to Exploded View.

Carefully lower table to remove the engine, the transmission and the front suspension member. When performing work, observe the following caution:

CAUTION:

• Confirm there is no interference with the Nissan Murano vehicle.

• Repeatedly check to ensure all harnesses are disconnected before and during engine removal.

• Check all connection points have been disconnected.

• Keep in mind the center of Nissan Murano vehicle gravity changes. If necessary, use jack(s) to support the vehicle at rear jacking point(s) to prevent it from falling off the lift.

Separation

Install engine slingers into front of cylinder head (bank 1) and rear of cylinder head (bank 2).

• Type 1

(1)	: Engine rear slinger
(2)	: cylinder head (bank 2)
(3)	: cylinder head (bank 1)
(4)	: Engine front slinger (upper)
(5)	: Engine front slinger (lower)
	: Engine front

• Type 2

(A): Cylinder head (bank 1)

(B): Cylinder head (bank 2)

Disconnect vacuum hose from front engine mounting insulator.

Remove CVT fluid level indicator and CVT charging pipe. Refer to Exploded View.

Remove starter. Refer to Removal and Installation.

Remove exhaust manifold and three way catalyst. Refer to Exploded View.

Remove front drive shaft (LH/RH). Refer to Removal and Installation (LH) and Removal and Installation (RH).

Remove nut from engine mounting insulator (rear). Refer to Exploded View.

Remove nut from engine mounting insulator (front). Refer to Exploded View.

Disconnect CVT unit harness connector from CVT.

Remove transfer assembly. Refer to Removal and Installation.

Remove transmission to engine bolts. Refer to Exploded View.

Separate engine and transmission assembly. Refer to Removal and Installation.

Lift the engine from the front suspension member.

CAUTION:

• Repeatedly check to ensure all harnesses are disconnected before and during engine lifting.

• Avoid spilling engine oil or grease onto the engine mounting insulators to prevent damage to engine mounting insulators.

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:

• Do not damage the engine mounting insulator. Do not spill engine oil on the engine mounting insulator.

• Check all mounting insulators are seated properly, then tighten nuts and bolts.

INSPECTION AFTER INSTALLATION

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If there is less than required quantity, fill to the specified level. Refer to Fluids and Lubricants.

• Use procedure below to check for fuel leakage.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.

• Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

  NOTE:

  If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level, if necessary.
