Cooling Fan Assembly

Remove and replace the cooling fan assembly on a 2017 Maserati Levante 3.0L V6 Twin Turbo, including disconnecting electrical connections and radiator components.

Warnings

Tools required

Parts

• Cooling fan assembly × 1 — Use OEM specification
• Upper radiator hose clamp × 1 — Use OEM specification
• Lower radiator hose clamp × 1 — Use OEM specification
• Maserati OAT Coolant × 1 — Factory coolant or equivalent

Fluids

• Maserati OAT Coolant — 10 qt

Preparation

1. Ensure engine is completely cold to touch (minimum 2 hours after operation)
2. Position vehicle on level ground and engage parking brake
3. Remove engine cover by lifting from rear and pulling forward to release clips
4. Disconnect negative battery terminal and wait 5 minutes for system capacitors to discharge
5. Place coolant drain pan under radiator drain petcock location (driver side lower radiator tank)

Procedure

1. 1

   Drain coolant from radiator
   Locate the drain petcock on the lower driver side of the radiator. Slowly open the petcock counterclockwise by hand to begin draining coolant. Allow coolant to drain until flow stops (approximately 4-5 quarts). Close petcock hand-tight once draining is complete.

   Drain Petcock7 Nm (5 lb-ft)
2. 2

   Disconnect upper radiator hose
   Locate the upper radiator hose connection at the top of the radiator (passenger side). Use hose clamp pliers or flathead screwdriver to release the spring clamp and slide it back along the hose approximately 3-4 inches. Twist the hose gently to break the seal, then pull it off the radiator neck. Have a rag ready to catch residual coolant.
3. 3

   Remove air intake duct (if necessary)
   If the air intake duct restricts access to the cooling fan assembly, loosen the clamps at both ends using a flathead screwdriver and remove the intake duct by pulling it straight up and out. Set aside for reinstallation.
4. 4

   Disconnect fan electrical connector
   Locate the cooling fan electrical connector on the driver side of the fan shroud. Press the release tab and pull the connector straight apart. Note the routing of the wiring harness for reinstallation. If present, release any wire retaining clips from the fan shroud.
5. 5

   Disconnect transmission cooler lines (if equipped)
   On AWD models or those with auxiliary transmission cooling, disconnect any transmission cooler lines attached to the radiator or fan shroud. Use a flare nut wrench if applicable and cap open lines immediately to prevent contamination. Mark line positions for correct reinstallation.
6. 6

   Remove fan shroud mounting bolts
   Locate the fan shroud mounting bolts at the top and sides of the fan assembly (typically 4-6 bolts total). Using a 10mm socket, remove all mounting bolts securing the fan assembly to the radiator. Keep bolts organized for reinstallation.
   ⚠Support the fan assembly with one hand while removing the final bolt to prevent it from falling and damaging radiator fins or hoses.

7. 7

   Remove cooling fan assembly
   With all mounting bolts removed, carefully lift the cooling fan assembly straight up and out of the engine bay. The assembly may need to be tilted slightly to clear obstructions. Take care not to contact or damage the radiator fins during removal. Inspect the fan blades for cracks or damage before setting aside.
8. 8

   Inspect radiator mounting points
   With the fan removed, inspect the radiator mounting bosses and rubber isolators where the fan shroud attaches. Check for cracks, deterioration, or damage. Clean any debris or old coolant residue from the mounting surfaces using a wire brush and shop rags. Verify radiator fins are not damaged from fan contact.
9. 9

   Install new cooling fan assembly
   Position the new cooling fan assembly above the radiator, ensuring proper orientation (fan motor typically on driver side). Carefully lower the assembly into place, aligning the mounting tabs with the radiator mounting bosses. The shroud should seat flush against the radiator mounting points.
10. 10

    Install and torque fan mounting bolts
    Install all fan shroud mounting bolts finger-tight first to ensure proper alignment. Once all bolts are started, torque each bolt to specification in a criss-cross pattern to ensure even pressure distribution and proper seating of the fan assembly against the radiator.

11. 11

    Reconnect electrical connector and accessories
    Reconnect the cooling fan electrical connector, ensuring it clicks firmly into place. Route the wiring harness in its original position and secure with any retaining clips. If transmission cooler lines were disconnected, reconnect them now and torque to specification if applicable.
12. 12

    Reinstall upper radiator hose
    Clean the radiator hose neck and hose interior end with a shop rag. Slide the hose clamp onto the hose if a new clamp is being installed. Push the upper radiator hose firmly onto the radiator neck until it seats completely. Position the clamp 1/4 inch from the hose end and tighten to specification.

    Refill cooling system
    Using Maserati OAT coolant, slowly fill the cooling system through the expansion tank until coolant reaches the MAX line. Allow time for air pockets to escape. Reconnect the negative battery terminal. Start the engine and allow it to reach operating temperature (approximately 195°F) with the heater on maximum to purge air from the system. Monitor coolant level and add as needed.

Reassembly

1. Reinstall air intake duct if it was removed, securing clamps firmly
2. Reinstall engine cover by aligning front clips and pressing down firmly at rear until it clicks into place
3. Double-check that no tools or rags were left in the engine bay
4. Verify all electrical connectors are fully seated and locked

Verification

• Start engine and verify cooling fan activates when engine reaches operating temperature (typically 195-205°F)
• Check for coolant leaks around radiator hose connections and drain petcock while engine is at operating temperature
• Verify fan runs smoothly without excessive noise or vibration
• Confirm coolant level is at MAX line on expansion tank after full heat cycle
• Test fan operation by turning air conditioning to maximum; fan should activate immediately
• Verify no warning lights are illuminated on instrument cluster related to cooling system
