Cooling Fan Motor

This procedure covers the removal and replacement of the cooling fan motor assembly on a 2017 Maserati Levante with 3.0L V6 Twin Turbo engine, including partial coolant drainage and shroud removal.

Warnings

Tools required

Parts

• Cooling fan motor assembly × 1 — Use OEM specification
• Upper radiator hose clamp (if damaged) × 1 — Use OEM specification
• Fan shroud clips (if broken) × 4 — Use OEM specification

Fluids

• Maserati OAT Coolant — 2 qt

Preparation

1. Park vehicle on level surface and allow engine to cool completely (minimum 2 hours)
2. Disconnect negative battery terminal and wait 5 minutes for system capacitors to discharge
3. Remove engine cover by pulling upward on front corners to release clips, then lift rearward
4. Place drain pan under radiator drain petcock on driver side lower corner of radiator
5. Verify cooling system is not pressurized by carefully cracking radiator cap slightly and listening for air release

Procedure

1. 1

   Drain partial coolant
   Locate the drain petcock on the lower driver side of the radiator. Open the petcock by turning counterclockwise and drain approximately 2 quarts of coolant into the drain pan. This will lower the coolant level below the upper radiator hose connection. Once drained, hand-tighten the petcock.

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

   Disconnect upper radiator hose
   Locate the upper radiator hose connection at the radiator inlet on the passenger side. Use pliers to compress and slide the hose clamp back approximately 2 inches away from the radiator neck. Twist the hose gently to break the seal, then pull firmly to remove from radiator inlet. Be prepared for residual coolant spillage.
   ⚠Do not pry the hose off with screwdrivers as this will damage the radiator inlet neck. Twist and pull only.

3. 3

   Remove fan shroud upper cover
   Locate the upper fan shroud cover secured with multiple screws around the perimeter. Remove all cover screws using an 8mm socket. There are typically 6-8 screws depending on configuration. Lift the cover straight up and away from the engine bay. Set aside with hardware.

   Cover Screws11 Nm (8 lb-ft)
4. 4

   Disconnect cooling fan electrical connector
   Locate the main cooling fan motor electrical connector on the driver side of the fan shroud assembly. Press the locking tab and pull the connector straight away from the fan motor. If equipped with a secondary connector for variable speed control, disconnect it as well. Inspect connector terminals for corrosion.

   Electrical Connector5 Nm (4 lb-ft)
5. 5

   Remove fan shroud mounting bolts
   The fan shroud is secured to the radiator with mounting bolts at multiple locations around the perimeter. Using a 10mm socket, remove all mounting bolts securing the shroud to the radiator core support. There are typically 4-6 bolts. Keep bolts organized for reinstallation.
   ℹ️Some bolts may be difficult to access due to tight clearances around the turbocharger heat shields. Use extensions as needed.

   Mounting Bolts28 Nm (21 lb-ft)
6. 6

   Remove fan shroud assembly
   With all mounting bolts removed, carefully lift the entire fan shroud assembly straight upward out of the engine bay. The assembly is bulky and may require tilting slightly to clear surrounding components. Take care not to damage the radiator fins or AC condenser during removal. Set the assembly on a clean work surface.
   ⚠The shroud assembly weighs approximately 15 pounds and has sharp edges. Use both hands and maintain control during removal.
7. 7

   Remove fan motor from shroud
   With the shroud assembly on the workbench, locate the fan motor mounting bolts securing the motor to the shroud housing. Remove all fan motor bolts using an 8mm socket. The motor is typically secured with 3-4 bolts. Separate the fan motor from the shroud. Note the orientation of any alignment pins or locating tabs.

   Install new fan motor
   Position the new cooling fan motor into the shroud housing, ensuring all alignment pins are properly seated and the electrical connector port faces the correct direction (driver side). Install all fan motor bolts and torque in a cross pattern to specification. Verify the fan blade spins freely without binding or rubbing.

9. 9

   Reinstall fan shroud assembly
   Carefully lower the complete fan shroud assembly back into the engine bay, aligning the mounting points with the radiator core support. Ensure the shroud seats properly against the radiator without gaps. Install all mounting bolts finger-tight first, then torque to specification in a cross pattern to ensure even pressure distribution.

10. 10

    Reconnect electrical and upper hose
    Reconnect the cooling fan motor electrical connector(s) until the locking tab clicks into place. Tug gently to verify secure connection. Reinstall the upper radiator hose onto the radiator inlet, pushing firmly until fully seated. Position the hose clamp over the connection point approximately 1/2 inch from the end and tighten to specification.

    Reinstall shroud cover
    Position the upper fan shroud cover back onto the shroud assembly, aligning all mounting holes. Install all cover screws and torque to specification in a progressive pattern to avoid warping the cover.

12. 12

    Refill and bleed cooling system
    Remove the radiator cap completely. Using a funnel, slowly add Maserati OAT coolant to the radiator until it reaches the base of the filler neck. Allow time for air bubbles to escape. Reconnect the negative battery terminal. Start the engine and allow it to warm to operating temperature with the heater on maximum. Monitor coolant level and add as needed until level stabilizes. Install radiator cap securely once system is fully bled and coolant level is correct.

Reassembly

1. Reinstall engine cover by aligning rear mounting points first, then pressing down on front corners until clips engage
2. Inspect entire cooling system for leaks, paying special attention to upper radiator hose connection and drain petcock
3. Verify coolant reservoir is filled to MAX mark when cold
4. Clean any spilled coolant from engine bay components to prevent odor when engine warms

Verification

• With engine at operating temperature, verify cooling fan activates when AC is turned on or when coolant temperature reaches approximately 205°F
• Listen for abnormal fan motor noise such as grinding, squealing, or excessive vibration
• Check for coolant leaks around upper radiator hose connection after first heat cycle
• Verify no warning lights appear on instrument cluster related to cooling system
• Test fan operation at multiple speeds if equipped with variable speed control by monitoring during city driving and highway conditions
• Confirm coolant level remains stable after 2-3 drive cycles
