Engine Oil

The 2023 GMC Acadia is available with two engine options: a turbocharged 2.0L four-cylinder and a 3.6L V6. The 2.0L turbo requires 0W-20 synthetic oil, while the 3.6L V6 uses 5W-30 synthetic oil. Both oils must be licensed to the GM dexos1 Gen3 specification. Using an oil that is not dexos1-licensed can lead to sludge formation, increased wear, and potentially void your warranty. The 2.0L has an oil capacity of 5.3 quarts, while the 3.6L has a capacity of 6.0 quarts. Always verify the oil fill level on the dipstick after an oil change.

Engine Coolant

The 2023 GMC Acadia uses a 50/50 mixture of clean, drinkable water and OAT (Organic Acid Technology) DEX-COOL coolant. The cooling system capacity is 9.3 quarts for the 2.0L and 11.8 quarts for the 3.6L. It is critical to never mix DEX-COOL with other coolant types, such as HOAT (Hybrid Organic Acid Technology) or IAT (Inorganic Acid Technology) coolants, as this can cause the coolant to gel and lead to overheating and engine damage. When topping off the coolant, use a pre-mixed 50/50 DEX-COOL product or mix your own using a 1:1 ratio of concentrated DEX-COOL and distilled water.

Transmission Fluid

All 2023 GMC Acadia models are equipped with a nine-speed automatic transmission that requires DEXRON VI automatic transmission fluid. The transmission fluid capacity is 5.3 quarts for the 2.0L and 6.4 quarts for the 3.6L. It is important to only use a licensed DEXRON VI fluid, as using a universal or multi-vehicle ATF can lead to poor shifting, transmission shudder, and premature wear. The transmission fluid is considered "fill-for-life," but many technicians recommend a fluid and filter change every 50,000 miles to ensure long-term reliability.

Transfer Case Fluid

The transfer case in all-wheel-drive models requires 75W-90 synthetic gear oil. The transfer case has a fluid capacity of 1.1 quarts. The fluid should be changed every 50,000 miles, or more frequently if the vehicle is used for towing or off-roading.

Rear Differential Fluid

The rear differential in all-wheel-drive models also requires 75W-90 synthetic gear oil. The rear differential has a fluid capacity of 1.1 quarts. The fluid should be changed every 50,000 miles, or more frequently if the vehicle is used for towing or off-roading.

Brake Fluid

The 2023 GMC Acadia uses DOT 4 brake fluid. The brake fluid reservoir has a capacity of about 1.0 quart. It is important to use a fresh, sealed container of brake fluid, as it is hygroscopic and will absorb moisture from the air. The brake fluid should be flushed and replaced every two to three years, as contaminated fluid can lead to a soft brake pedal and reduced braking performance.

Power Steering Fluid

The 2023 GMC Acadia is equipped with an electric power steering system, so there is no power steering fluid to check or change.

Washer Fluid

There is no specific type of washer fluid required, but a good quality fluid with a freezing point of -30°F (-34°C) is recommended. The washer fluid reservoir has a capacity of 1.3 gallons (5.0 liters).

Diesel Exhaust Fluid (DEF)

The 2023 GMC Acadia is not available with a diesel engine, so there is no need for Diesel Exhaust Fluid (DEF).
