Engine Oil

For the 2020 Chevrolet Equinox, regardless of engine (1.5L or 2.0L turbocharged, or 1.6L diesel), General Motors specifies SAE 0W-20 full synthetic engine oil meeting the dexos1 Gen2 (or newer Gen3) specification. This is crucial for optimal engine protection, fuel efficiency, and to maintain warranty compliance. Always look for the official dexos logo on the oil bottle. The oil capacity for both gasoline engines is approximately 5.0 quarts (4.7 liters) with a filter change. The oil change interval is typically indicated by the vehicle's Oil Life Monitoring (OLM) system, which can range from 7,500 to 12,000 miles or 1 year, whichever comes first. It is always recommended to follow the OLM system. Using an oil that does not meet the dexos1 specification can lead to issues like Low Speed Pre-Ignition (LSPI) in turbocharged engines and can void your powertrain warranty.

Engine Coolant

Your 2020 Chevrolet Equinox requires Dex-Cool engine coolant, which is an Organic Acid Technology (OAT) antifreeze. It is typically orange in color. The GM specification for this coolant is GM6277M. It's vital to use only Dex-Cool or an officially licensed Dex-Cool compatible coolant. Mixing Dex-Cool with other types of coolants (like those with Hybrid Organic Acid Technology (HOAT) or Inorganic Acid Technology (IAT)) can cause chemical reactions leading to silicate dropout, gel formation, and corrosion, potentially damaging the cooling system components. The cooling system capacity is approximately 7.0-8.0 quarts depending on the specific engine and trim. The recommended service interval for Dex-Cool is typically every 5 years or 150,000 miles, whichever comes first.

Transmission Fluid

The 2020 Chevrolet Equinox utilizes an automatic transmission that requires Dexron VI Automatic Transmission Fluid. This fluid is backward compatible with earlier Dexron specifications (Dexron III, Dexron II), but Dexron VI offers improved friction durability, wear protection, and viscosity stability. The transmission fluid capacity for a drain and fill is typically around 8.9 – 9.0 quarts, but a complete flush will require more. Always follow the manufacturer's recommended procedure for checking the fluid level, as many modern transmissions do not have a traditional dipstick and require specific temperature ranges for an accurate reading. GM generally considers the transmission fluid "lifetime fill," but for optimal longevity, especially under severe driving conditions, many professional technicians recommend a fluid and filter change between 60,000 to 100,000 miles. Never use "universal" ATF; always ensure the fluid specifically states Dexron VI compliance.

Transfer Case Fluid (AWD Models Only)

For 2020 Chevrolet Equinox models equipped with All-Wheel Drive (AWD), the transfer case also uses Dexron VI Automatic Transmission Fluid, the same fluid as the automatic transmission. The capacity for the transfer case is approximately 1.0 – 1.25 quarts. The recommended service interval for transfer case fluid is often around 50,000 to 100,000 miles, depending on driving conditions. Regular maintenance helps ensure the smooth operation and longevity of the AWD system. Consult your owner's manual for the precise service schedule.

Front and Rear Differential Fluid

The front differential, integrated within the transmission on AWD models, and the rear differential on AWD models, require specific gear oil. For the front differential, a SAE 75W-90 Synthetic Axle Lubricant is typically specified, often corresponding to GM Part No. 88862624 or an equivalent. The capacity is approximately 0.75 quarts. For the rear differential, a similar hypoid gear oil is used, often the same GM Part No. 88862624 or equivalent, with a capacity of approximately 0.6-0.7 quarts. Always verify the exact specification and capacity in your owner's manual or OEM service information. Some rear differentials may have specific requirements or friction modifiers, although less common on this vehicle. Differential fluid changes are typically recommended between 50,000 to 100,000 miles, particularly for vehicles that frequently tow or drive in demanding conditions.

Brake Fluid

The 2020 Chevrolet Equinox typically uses DOT 4 or Super DOT 4 brake fluid. It is a glycol-ether based fluid. Never use DOT 5 (silicone-based) brake fluid, as it is incompatible with the ABS and hydraulic brake system components designed for DOT 3, DOT 4, or DOT 5.1. DOT 5.1 is also glycol-ether based and compatible, offering a higher boiling point, but DOT 4 is the minimum requirement. Brake fluid is hygroscopic, meaning it absorbs moisture over time, which lowers its boiling point and can lead to corrosion in the brake system. GM recommends inspecting brake fluid every 15,000 miles or 12 months and replacing it every 2-5 years, depending on environmental conditions and driving habits. Follow the owner's manual for specific recommendations.

Power Steering Fluid

The 2020 Chevrolet Equinox is equipped with an Electric Power Steering (EPS) system, which means it does not use hydraulic power steering fluid. Therefore, there is no power steering fluid to check or replace.

Windshield Washer Fluid

Any commercially available quality windshield washer fluid is suitable for your 2020 Chevrolet Equinox. GM often recommends GM Optikleen Washer Fluid, but any major brand will suffice. For optimal performance in freezing temperatures, ensure the fluid provides adequate freeze protection for your climate. The capacity of the washer fluid reservoir is approximately 1 gallon (3.8 liters). It's advisable to avoid using plain water, as it can freeze in colder temperatures and does not effectively clean road grime.

Diesel Exhaust Fluid (DEF)

For 2020 Chevrolet Equinox models with the 1.6L diesel engine (not available in all markets), Diesel Exhaust Fluid (DEF) is required for the Selective Catalytic Reduction (SCR) system. DEF must meet the ISO 22241 (AdBlue) standard. The DEF tank capacity is usually around 4.5 – 5.0 gallons. The vehicle's instrument cluster will provide warnings when the DEF level is low. Using incorrect fluid or contaminated DEF can damage the SCR system and lead to costly repairs. Check your owner's manual for specific DEF refill procedures and capacity.
