Scheduled Servicing Overview
The 2021 Alfa Romeo Giulia AWD follows a structured maintenance plan based on both distance and time intervals, as detailed in the official owner's manual. Correct servicing is crucial for guaranteeing a long life for the vehicle under the best conditions .
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 FCA US LLC. Failure to have them carried out may invalidate the New Vehicle Limited Warranty. You are advised to 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 :
| Component | Required Action |
|---|---|
| Engine coolant level | Check and top off |
| Brake fluid level | Check - if insufficient, see an authorized dealer as soon as possible |
| Windshield washer fluid level | Check and top off |
| Tire inflation pressure and condition | Inspect and adjust pressure |
| Lighting system operation | Check headlights, direction indicators, hazard warning lights, etc. |
| Windshield wiper/washer operation | Check operation and blade positioning/wear |
| CV/Universal joints | Inspect |
Engine Oil Level:
Oil consumption depends on conditions and driving style. The engine oil level must be checked every 1,860 miles (3,000 km) and topped off if necessary .

Oil Degradation Monitoring:
If the oil degradation ratio (data collectable from the diagnostic device) is more than 80% (oil quality less than 20%), engine oil and filter replacement is recommended .
Transfer Case Service - AWD Only
The transfer case in the Giulia AWD (Alfa Romeo's Q4 all-wheel drive system) enables power transfer between the front and rear wheels. The transfer case contains chain-driven gears that move through fluid to keep components cool, well-lubricated, corrosion-free, and to prevent wear and tear .
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 has become dark or gritty, around the time of its service interval, it will need to be changed .
Factory Replacement Interval:
The 2021 factory maintenance plan specifies transfer case oil replacement as a mandatory operation for AWD models only. Transfer case fluid replacement intervals vary by manufacturer, typically ranging 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
- Repairs have been completed on the transfer case
- Rattle or grinding noise coming from underneath your car
Critical Warning: When the transfer case fluid is replaced, only the exact manufacturer-specified fluid should be used - using the incorrect fluid will cause premature failure. Like poor engine oil maintenance, transfer case problems will eventually occur if transfer case fluid replacement is neglected .
Consequences of Neglect:
Driving your Alfa Romeo Giulia with neglected transfer case maintenance can lead to a breakdown and possible loss of control. Have your transfer case fluid replacement performed in a timely manner .
Engine Oil Change Guidance
Oil Change Indicator System:
The actual interval for changing engine oil and replacing the engine oil filter depends on the 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
Oil Level Checking :
- Check engine oil level every 1,860 miles (3,000 km)
- Top off if necessary
CAUTION: Never overfill the engine with oil. Excess oil can damage the engine. Never exceed the MAX level when topping up.
When You May Need an Oil Change Sooner:
- Check engine light is on
- Knocking noise coming from the engine
- Oil smell inside the vehicle
- Excess amount of vehicle exhaust
- Hauling heavy loads
- Driving in dusty terrain or off-road
- Driving at low speeds for long distances
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 during the monthly check, see an authorized dealer as soon as possible .
Spark Plugs
Replacement Interval :
- 60,000 miles (NAFTA market)
- Other markets: 60,000 km
Important: The spark plug change interval is mileage-based only - yearly intervals do not apply. Use only spark plugs specified by Alfa Romeo for the Giulia engine. Incorrect plugs can cause misfires, poor fuel economy, and engine damage.
Accessory Drive Belt
The accessory drive belt(s) require visual inspection of condition and tensioning at every scheduled service .
Replacement Intervals :
| Usage Condition | Maximum Mileage | Time Interval |
|---|---|---|
| Normal conditions (non-dusty areas) | 36,000 miles (60,000 km) | Every 4 years |
| Dusty areas and/or demanding use (cold climates, town use, long idling periods) | 18,000 miles (30,000 km) | Every 2 years |
Owner Guidance: When replacing belts, consider replacing tensioners as well. 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.
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 air cleaner and 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 . The maintenance plan shows this as a mandatory operation at the 5-year, 10-year, and 15-year intervals.
Additional Service Components
Fuel Filter:
Replacement is required at every 10,000-mile service interval (mandatory operation) .
Battery:
Check battery charge status with the proper instrument at every scheduled service.
Tires:
Check tire condition/wear and adjust pressure at each service. Check the tire repair kit recharge condition and expiration date.
Brake System:
Visually inspect conditions and wear of front/rear disc brake pads at every service. Check operation of pad wear indicators.
Cooling System:
Engine coolant level should be checked monthly (every 600 miles) and topped off as needed .
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.
Carbon Ceramic Brakes (if equipped - Quadrifoglio models):
The actual interval for changing the brake pads and the carbon ceramic brake discs depends on the vehicle usage conditions and is signaled by the warning light or message on the instrument panel. After each disc replacement, reset the warning light using the diagnostic socket .
