Scheduled Servicing Overview for AWD Giulia

The 2025 Alfa Romeo Giulia AWD follows a structured preventive maintenance plan based on both distance and time intervals. The scheduled servicing plan includes specific requirements for AWD components, primarily the transfer case, which is not present on rear-wheel drive versions .

How the System Works:

• Alfa Romeo has planned a series of checks and services at fixed intervals based on distance and time
• Scheduled Servicing is offered by an authorized dealer according to a set time schedule
• Before each service, follow the instructions in the Scheduled Servicing Plan (periodically check fluid levels, tire pressure, etc.)
• If additional replacements or repairs are needed beyond scheduled operations, they require the owner's explicit consent

Critical Warranty Note:

Scheduled Servicing intervals are required by the manufacturer. Failure to have them carried out may invalidate the New Vehicle Limited Warranty . Inform an authorized dealer of any small operating irregularities without waiting for the next service.

Plan Notation:

• (o) Recommended operations - suggested for optimal vehicle health
• (mandatory) Mandatory operations - required to maintain warranty coverage

Owner Periodic Checks (Between Services)

The following checks are the owner's responsibility between professional service visits. These should be performed every month or every 600 miles (1,000 km) or before long trips :

Engine Oil Level:

Oil consumption depends on driving conditions and style. The engine oil level must be checked every 1,860 miles (3,000 km) and topped off if necessary .

Heavy Usage & Severe Duty Conditions

If the vehicle is used under any of the following conditions, more frequent maintenance is required :

Checks Required More Frequently Under Heavy Usage :

• Check cleanliness of hood and trunk locks, cleanliness and lubrication of linkage
• Visually inspect conditions of: engine, transmission, pipes and hoses (exhaust/fuel system/brakes) and rubber elements (sleeves/bushes, etc.)
• Check battery charge and battery fluid level (electrolyte)
• Visually inspect conditions of the accessory drive belts
• Check and, if necessary, change engine oil and replace oil filter
• Check and, if necessary, replace cabin air filter
• Check and, if necessary, replace engine air cleaner

Severe Duty Oil Change Requirement :

Vehicles operated in a dusty and off-road environment, or predominantly at idle or very low engine RPM, are classified as Severe Duty. It is recommended that you change engine oil at 4,000 miles (6,500 km) or 350 hours of engine run time.

Factory Maintenance Plan - 2.0L Engine with AWD

The following maintenance requirements are extracted from the official 2025 Alfa Romeo Giulia Owner's Manual :

Regular Inspections (Every 10,000 miles / 1 year) :

• Check battery charge status with proper instrument (mandatory)
• Check tire condition/wear and adjust pressure; check tire repair kit condition (mandatory)
• Check operation of lighting system (mandatory)
• Check and top up fluid levels (mandatory)
• Check engine control system via diagnostic tool; check engine oil degradation (mandatory)
• Visually inspect exterior bodywork, underbody protection, pipes/hoses, rubber elements (mandatory)
• Check position/wear of front windshield wiper blade (mandatory)
• Check operation of wiper/washer system and adjust nozzles (mandatory)
• Check cleanliness of hood and trunk locks and linkage (mandatory)
• Visually inspect front/rear disc brake pads and wear indicators (mandatory)
• Visually inspect condition and tensioning of accessory drive belt(s) (mandatory)

Transfer Case Service - AWD Only

The transfer case in the Giulia AWD is a critical component that enables power distribution between the front and rear wheels . Inside the transfer case, a chain and gears splash fluid to keep components cool, lubricated, and corrosion-free.

Why Transfer Case Fluid Requires Replacement:

During normal driving, the transfer case fluid is exposed to heat and friction, which gradually break down the fluid and cause it to lose its lubricating properties . When the fluid becomes dark or gritty, it requires replacement. The interval varies by manufacturer but typically ranges from 40,000 km to 100,000 km and beyond .

Symptoms That Indicate Transfer Case Service is Needed :

• Transfer case fluid is dark and discolored
• Transfer case fluid level is low
• Rattle or grinding noise coming from underneath the car
• Recent repairs have been completed on the transfer case

Critical Warning: Only the exact manufacturer-specified fluid should be used for transfer case service. Using incorrect fluid will cause premature failure .

Consequences of Neglect:

Driving an AWD Giulia with neglected transfer case maintenance can lead to a breakdown and possible loss of control. Transfer case problems will eventually occur if fluid replacement is neglected, similar to poor engine oil maintenance .

Engine Oil Change Guidance

Oil Change Indicator System:

The actual interval for changing engine oil and replacing the engine oil filter depends on vehicle usage conditions and is signaled by the warning light or message in the instrument panel .

Maximum Limits :

• Never exceed 1 year between oil changes
• Never exceed 10,000 miles (16,000 km) between oil changes
• The warning light may indicate a need for earlier changes based on driving conditions
• If oil degradation ratio exceeds 80% (oil quality less than 20%), engine oil and filter replacement is recommended

Severe Duty:

4,000 miles (6,500 km) or 350 engine run hours if operated in dusty/off-road environments or predominantly at idle/low RPM .

Oil Level Checking :

• Check engine oil level every 1,860 miles (3,000 km)
• For 2.0L engine: Oil level can be viewed on the instrument panel display after starting the engine
• For 2.9L engine (Quadrifoglio): Manual check using dipstick

CAUTION: Never overfill the engine with oil. Excess oil can damage the engine. Never exceed the MAX level when topping up .

Brake Fluid

Brake fluid replacement is a mandatory operation that must be done every 2 years, irrespective of mileage .

Why Every 2 Years:

Brake fluid is hygroscopic - it absorbs moisture from the air over time, which lowers the boiling point and can cause brake fade under hard braking. Moisture also promotes internal corrosion of brake system components.

Owner Check: If the brake fluid level is insufficient, see an authorized dealer as soon as possible .

Accessory Drive Belt (Serpentine Belt)

The accessory drive belt(s) replacement is listed as a mandatory operation in the 2025 maintenance plan .

Timing Belt vs. Accessory Drive Belt:

According to general guidance for the Giulia, the timing belt (toothed timing drive belt) life typically oscillates between 37,280 miles and 99,420 miles or 5 years, whichever comes first . The 2025 maintenance plan specifies accessory drive belt replacement as mandatory at certain intervals.

Owner Guidance for Belt Replacement :

When replacing the belt, replace the tensioners as well. If the belt activates the water pump, replace it too. The highest cost of this service is the labor, not the replacement part itself. Reusing old tensioners risks premature failure and repeating the entire expense.

Accessory Drive Belt Inspection:

Visual inspection of condition and tensioning is required at every scheduled service (every 10,000 miles) .

Spark Plugs

Replacement Interval :

• NAFTA market: 60,000 miles
• Other markets: 60,000 km

Important: Yearly intervals do not apply - this is a mileage-based interval only. Use only spark plugs specified by Alfa Romeo for the Giulia engine. Incorrect plugs can cause misfires, poor fuel economy, and engine damage.

Engine and Cabin Air Filters

Standard Intervals:

Follow the maintenance schedule for replacement.

Dusty Area Requirement :

If the vehicle is used in dusty areas, the engine and/or cabin air filter must be replaced every 10,000 miles (16,000 km) .

SOS Backup Battery (If Equipped)

If your Giulia is equipped with an SOS backup battery (for the emergency call system), it must be replaced every 5 years, regardless of mileage . This appears as a mandatory operation at the 5-year, 10-year, and 15-year intervals in the maintenance plan.

Engine Coolant

Engine coolant replacement is listed as a mandatory operation in the maintenance plan . Coolant level should be checked monthly (every 600 miles) and topped off as needed.

When adding coolant, use the fluid described in the owner's manual. Be careful when topping off under the hood to minimize spills on top of the engine .

Additional Service Components

Battery :

• Check battery charge status at every scheduled service
• Batteries do not require electrolyte refilling, but periodic efficiency checks are necessary
• If the charge level remains below 50% for an extended period, the battery may be damaged by sulfating

Fuel Filter:

Replace the additional fuel filter (if equipped) according to the mandatory maintenance schedule (shown at regular intervals) .

Tires:

Check tire condition/wear and adjust pressure at each service. Check the tire repair kit recharge condition and expiration date .

Lighting System:

Check operation of headlights, direction indicators, hazard warning lights, trunk lid lights, passenger compartment lights, glove compartment lights, and instrument panel warning lights at each service .
