2025 Chevrolet Equinox Complete Fluid Specifications

As an ASE-certified master technician, I know that using the exact factory-specified fluids is the most critical step in maintaining modern powertrains. The completely redesigned 2025 Chevrolet Equinox introduces new hardware, including updated transmission options (a CVT for FWD models and an 8-speed automatic for AWD models) bolted to the revised 1.5L Turbo engine. Using an incorrect fluid specification in these modern GM components can lead to catastrophic failures, voided warranties, and expensive headaches.

Below is your complete, master-tech-approved fluid specification guide for the 2025 Chevrolet Equinox.

Quick Reference

Transmission Fluid (FWD)	GM CVT Fluid (verify exact GM part # in manual)	Verify in owner's manual
Transmission Fluid (AWD)	DEXRON® ULV	Verify in owner's manual
Transfer Case (AWD)	75W-90 Gear Oil (API GL-5)	~0.5 qts (0.47 L)
Rear Differential (AWD)	75W-90 Gear Oil (API GL-5)	~0.7 qts (0.65 L)
Brake Fluid	DOT 4 Hydraulic Brake Fluid	Fill to MAX line
Power Steering	N/A (Electric Power Steering)	N/A
Washer Fluid	Standard Washer Fluid (-20°F in winter)	~1 Gallon
DEF	N/A (Gasoline powertrain)	N/A

Note: Capacities are approximate dry-fill or standard service estimates. Always verify exact levels using the dipstick, check plug, or level-check procedures outlined in OEM service information.

Engine Oil

For the 1.5L turbocharged 4-cylinder engine, GM strictly requires 0W-20 full synthetic oil that meets the dexos1™ Gen 3 specification.

Intervals and Pitfalls: The dexos1 Gen 3 specification was explicitly formulated to prevent Low-Speed Pre-Ignition (LSPI)—a highly destructive phenomenon common in small-displacement, direct-injected, turbocharged engines. Never substitute this with a standard API SP oil unless it explicitly carries the GM dexos1 Gen 3 license on the label. While the Equinox features an Oil Life Monitoring System (OLMS) that can stretch intervals up to 7,500 miles, I highly recommend dropping the oil and filter every 5,000 miles to maximize the life of the turbocharger bearings and timing chain components.

Engine Coolant

The 2025 Equinox cooling system utilizes GM's proprietary Dex-Cool® coolant. This is an Organic Acid Technology (OAT) antifreeze, distinctively orange in color.

Intervals and Pitfalls: A 50/50 mixture of Dex-Cool and clean, drinkable water (preferably distilled) is required. Never, under any circumstances, mix Dex-Cool with older conventional green coolants (IAT) or universal Hybrid Organic Acid Technology (HOAT) coolants. Mixing incompatible chemistries will cause the coolant to gel, leading to plugged heater cores, overheating, and blown head gaskets. Factory service intervals recommend a coolant flush every 150,000 miles or 5 years, but flushing every 50,000 miles ensures optimal corrosion protection for the aluminum engine block and heater core.

Transmission Fluid

The 2025 Equinox introduces a split in transmission hardware: Front-Wheel Drive (FWD) models utilize a Continuously Variable Transmission (CVT), while All-Wheel Drive (AWD) models utilize an 8-speed automatic transmission.

• FWD (CVT): Requires specific GM CVT Fluid. Do not use standard ATF.
• AWD (8-Speed Automatic): Requires DEXRON® ULV (Ultra-Low Viscosity) transmission fluid.

Intervals and Pitfalls: DEXRON ULV is significantly thinner than older fluids like DEXRON VI to improve fuel economy. Never use "universal" ATF, DEXRON VI, or ATF+4 in the 8-speed, as it will cause incorrect line pressures, harsh shifting, and clutch pack failure. Similarly, putting standard ATF in the CVT will destroy the pushbelt mechanism almost instantly. GM often claims transmissions are "sealed for life," but any master tech will tell you to perform a drain-and-fill every 45,000 to 60,000 miles to ensure transmission longevity.

Transfer Case and Rear Differential (AWD Models)

For AWD Equinox models, the Power Transfer Unit (PTU/transfer case) and Rear Drive Module (rear differential) both require a high-quality 75W-90 API GL-5 Gear Oil.

Intervals and Pitfalls: Since the Equinox utilizes an active AWD system, these gearboxes hold a very small amount of fluid (less than a quart each) and work extremely hard. Because of this small capacity, fluid degradation happens quickly. It is highly recommended to replace the fluid in both the PTU and rear differential every 30,000 to 45,000 miles. Always make sure you can remove the fill plug before you remove the drain plug—a classic technician pitfall!

Brake Fluid

The braking system requires standard DOT 4 hydraulic brake fluid.

Intervals and Pitfalls: DOT 4 fluid has a higher boiling point than DOT 3, which is necessary for modern ABS and stability control systems, but it is also more hygroscopic (it absorbs moisture from the air more rapidly). You must flush the brake fluid every 2 years or 30,000 miles, regardless of how the vehicle is driven. Moisture in the system lowers the boiling point—leading to a spongy pedal during panic stops—and causes internal corrosion in the expensive ABS hydraulic control unit. Never use silicone-based DOT 5 fluid, as it is strictly incompatible with ABS systems.

Power Steering

The 2025 Chevrolet Equinox utilizes an Electric Power Steering (EPS) rack. Because it is powered by an electric motor rather than a hydraulic pump, there is no power steering fluid to check, top off, or replace.

Windshield Washer Fluid

Use a high-quality, commercially available windshield washer fluid.

Intervals and Pitfalls: In regions that experience freezing temperatures, ensure the fluid is rated for at least -20°F (-29°C). Never run straight water in the reservoir, as it will freeze, expand, and crack the reservoir tank or damage the washer pump motor. Avoid using bug-wash fluids during the winter months, as they typically do not have antifreeze properties.
