Procedure

1. 1

   Perform engine oil and filter change
   Locate engine oil drain plug on oil pan. Position drain pan underneath and remove drain plug, allowing oil to drain completely (approximately 10 minutes). Remove oil filter using filter wrench. Clean filter mounting surface, apply thin film of new oil to new filter gasket, and install new filter hand-tight plus 3/4 turn. Install new drain plug washer and reinstall drain plug. Fill engine with 5.5 quarts of Selenia Racing 10W-60 oil. Start engine and verify no leaks, then check oil level with dipstick after engine reaches operating temperature.
2. 2

   Replace engine air filter and cabin air filter
   Open engine air filter housing by releasing clips or removing fasteners. Remove old air filter and inspect housing for debris. Install new air filter ensuring proper seating and seal. Secure housing. Locate cabin air filter access panel (typically behind glove box or under dashboard). Remove access panel, slide out old cabin filter noting airflow direction arrow. Install new cabin filter with arrow pointing in correct airflow direction and reinstall access panel.
3. 3

   Replace spark plugs
   Remove engine covers to access spark plug locations on both cylinder banks. Carefully disconnect ignition coil connectors and remove coil mounting bolts. Pull coils straight up to remove. Use compressed air to clean debris from spark plug wells. Remove old spark plugs using proper spark plug socket. Inspect plugs for abnormal wear patterns. Check gap on new spark plugs (verify specification for this twin turbo engine, typically 0.028-0.032 inches). Apply small amount of anti-seize to plug threads (avoid getting on electrodes). Install new plugs hand-tight, then tighten to specification. Reinstall ignition coils and connectors. Reinstall engine covers.
   ⚠Do not over-torque spark plugs in aluminum cylinder heads. Hand-tight plus 1/4 turn is typically sufficient if torque specification unavailable.
4. 4

   Service ZF 8-speed automatic transmission
   Locate transmission drain plug on underside of transmission pan. Place large drain pan underneath (transmission holds 10 quarts). Remove drain plug with new seal ready. Allow fluid to drain completely. Some models require removing pan for filter access - if equipped with serviceable filter, remove pan bolts in crisscross pattern, lower pan carefully, replace filter and pan gasket. Clean pan and magnet thoroughly. Reinstall pan and drain plug with new seals. Locate transmission fill plug on side of transmission. Using transmission fill adapter and pump, add ZF Lifeguard 8 fluid through fill port. Vehicle must be level and transmission fluid temperature must be 35-45°C (monitored via scan tool). Fill until fluid begins to weep from fill hole at proper temperature. Install fill plug. Cycle transmission through all gears with engine running, then recheck level at temperature.
   ⚠️Transmission fluid temperature is critical for proper fill level. Incorrect level will cause transmission damage. Scan tool monitoring is mandatory.
5. 5

   Service rear differential
   Locate rear differential fill plug (upper) and drain plug (lower). Remove fill plug first to ensure it's not seized before draining. Place drain pan under differential and remove drain plug with new seal ready. Allow gear oil to drain completely (approximately 2 quarts). Clean magnetic drain plug thoroughly. Install drain plug with new seal. Using fluid pump and appropriate adapter, fill differential with 75W-140 synthetic gear oil through fill hole until fluid reaches bottom of fill plug hole. Install fill plug with new seal.
6. 6

   Replace fuel filter
   Relieve fuel system pressure by removing fuel pump fuse and running engine until it stalls. Locate fuel filter (typically along frame rail or near fuel tank). Place absorbent rags around filter connections. Using fuel line disconnect tools if equipped with quick-connect fittings, disconnect fuel lines from both sides of filter. Remove filter mounting bracket. Install new fuel filter observing directional arrow for fuel flow. Reconnect fuel lines ensuring positive engagement. Reinstall fuel pump fuse. Cycle ignition to ON position several times to prime system without starting engine. Inspect for leaks before starting engine.
   ⚠️Fuel system is under high pressure. Relieve pressure before disconnecting any fuel lines. Have fire extinguisher accessible and work in well-ventilated area.
7. 7

   Perform brake fluid exchange
   Locate brake fluid reservoir and clean area around cap. Check current fluid level and condition. Using pressure bleeder or manual bleeding method with assistant, bleed brakes in this sequence: right rear, left rear, right front, left front. At each wheel, attach clear tube to bleeder valve and submerge other end in container. Open bleeder valve and allow old fluid to purge until fresh, clean DOT 4 Racing brake fluid flows through (color change visible). Close bleeder valve before pressure drops. Maintain reservoir level throughout process. After bleeding all four corners, verify firm brake pedal and top off reservoir to MAX line with fresh brake fluid.
   ⚠Never reuse brake fluid. Do not allow brake fluid to contact paint or get into differential or other lubricants.
8. 8

   Inspect and top off coolant system
   With engine completely cold, inspect coolant level in expansion tank. Check all coolant hoses, clamps, and connections for leaks or deterioration. Inspect radiator, intercoolers, and turbocharger coolant lines. If coolant level is low, add Maserati OAT coolant to proper level (between MIN and MAX marks on expansion tank). If significant coolant loss is noted, pressure test system to identify leaks. Check coolant freeze point with refractometer or test strips.
9. 9

   Perform comprehensive vehicle inspection
   Inspect all drive belts for cracks, glazing, or excessive wear. Check belt tensioners for proper operation. Inspect all suspension components, ball joints, tie rod ends, and control arm bushings for wear or damage. Check CV boots for tears or leaks. Inspect brake pads and rotors for remaining thickness and condition. Check tire tread depth and wear patterns. Inspect exhaust system including turbocharger connections for leaks or damage. Check battery terminals and condition. Inspect all fluid levels not serviced (power steering is electric, no fluid). Document any issues found for customer review.
10. 10

    Reset service indicators and perform final checks
    Connect scan tool and reset service interval indicators to reflect completed 90K service. Clear any non-critical fault codes that may have been set during service. Perform transmission adaptation procedure if required by scan tool after fluid service. Reinstall all undertray panels and engine covers. Lower vehicle and perform final visual inspection. Start engine and verify no warning lights. Test drive vehicle for 10-15 minutes, checking transmission shift quality, brake pedal feel, and overall operation. After test drive, recheck all fluid levels with vehicle on level surface and engine at operating temperature. Top off as necessary.

Reassembly

1. Ensure all drain plugs are installed with new sealing washers and properly tightened
2. Verify all filters are correctly seated and secured
3. Reinstall all protective panels and undertrays removed during service
4. Double-check that all fluid levels are correct at operating temperature on level surface
5. Verify all electrical connectors for ignition coils and sensors are fully engaged
6. Ensure no tools or rags are left in engine compartment

Verification

• Start engine and verify smooth idle with no warning lights illuminated
• Check for any fluid leaks under vehicle after 5 minutes of running
• Verify oil pressure reading is normal on instrument cluster
• Test drive vehicle and confirm smooth transmission shifting through all gears
• Verify brake pedal is firm and responsive with no sponginess
• Confirm all service interval indicators have been reset using scan tool
• Recheck all fluid levels after test drive with vehicle at operating temperature on level surface
• Document completed service with mileage and date for customer records
