Engine Oil

The 2022 Tesla Model Y is a Battery Electric Vehicle (BEV) and as such, does not utilize an internal combustion engine. Therefore, engine oil is not applicable to this vehicle.

Coolant

The Tesla Model Y utilizes a sophisticated thermal management system that requires a specific coolant type to maintain optimal operating temperatures for the battery, motors, and power electronics. This system is crucial for performance, efficiency, and battery longevity. Tesla mandates the use of a proprietary glycol mixture.

Type/Spec: Tesla Approved Glycol Mixture. It is typically a distinctive color, often blue or pink/purple, but color alone should not be used for identification. Always refer to your owner's manual or Tesla service documentation for the exact specification and part number.

Capacity: The coolant capacity can vary slightly. Always verify the correct capacity in your owner's manual or OEM service information before attempting any service.

Intervals: Unlike traditional ICE vehicles, the coolant in a Tesla is a long-life formulation. However, it is not considered "lifetime" and will require periodic inspection and replacement. Consult your owner's manual or Tesla's official service intervals. Using an incorrect coolant can lead to severe damage to the thermal management system components, including the battery and drive units, and may void your warranty. Never mix different types of coolants.

Transmission Fluid

Being an electric vehicle, the 2022 Tesla Model Y does not have a conventional multi-speed transmission that would require transmission fluid in the traditional sense. The electric motors directly drive the wheels through a single-speed reduction gear, which uses a specific gear oil, not a transmission fluid.

Drive Unit Fluid (Front/Rear)

Both the front and rear electric drive units in the Tesla Model Y contain a reduction gear system that requires a specific gear oil for lubrication and cooling. This fluid is critical for the longevity and efficient operation of the drive units.

Type/Spec: Tesla Specification Gear Oil. The exact specification is proprietary to Tesla. Do not use generic differential fluids or "universal" gear oils. Using an incorrect fluid can lead to premature wear, noise, and failure of the drive unit components.

Capacity: The capacity for both the front and rear drive units will be specified in your owner's manual. It is imperative to verify these values with the OEM service information.

Intervals: Tesla specifies service intervals for inspecting and potentially replacing the drive unit fluid. Adhere strictly to these recommendations to ensure proper function and warranty compliance.

Brake Fluid

The 2022 Tesla Model Y, like all modern vehicles, uses hydraulic brake fluid to actuate the braking system. The brake system in an EV is particularly critical, as it works in conjunction with regenerative braking.

Type/Spec: DOT 3 or DOT 4 Brake Fluid. Tesla typically recommends using a DOT 3 or DOT 4 fluid. DOT 4 has a higher boiling point than DOT 3, which can be beneficial during spirited driving or heavy use. Always confirm the exact specification in your owner's manual. Never use DOT 5 (silicone-based) fluid, as it is incompatible with ABS systems and can cause severe damage. DOT 5.1 is glycol-based like DOT 3 and 4, but always verify compatibility.

Capacity: The brake fluid reservoir capacity is relatively small. The exact volume required for a full flush will be in the OEM service information.

Intervals: Brake fluid is hygroscopic, meaning it absorbs moisture from the air, which lowers its boiling point and can lead to corrosion in the brake system. Tesla recommends periodic brake fluid flushes, typically every two years, regardless of mileage. This is a critical maintenance item for safety.

Power Steering Fluid

The 2022 Tesla Model Y utilizes an electric power steering system, which does not require hydraulic power steering fluid. This system is electronically assisted, eliminating the need for a fluid reservoir, pump, or hoses associated with traditional hydraulic power steering.

Washer Fluid

Maintaining clear visibility is crucial, and the windshield washer system on the Tesla Model Y is similar to conventional vehicles.

Type/Spec: Standard Windshield Washer Fluid. Any commercially available windshield washer fluid suitable for automotive use is acceptable. In colder climates, ensure you use a fluid rated for freezing temperatures to prevent the system from icing up.

Capacity: The washer fluid reservoir capacity is typically large enough for several uses, but the exact volume can be found in your owner's manual. Keep the reservoir topped off, especially before long journeys or during inclement weather.

Intervals: Top off as needed. There are no specific service intervals for washer fluid beyond ensuring proper levels.

DEF (Diesel Exhaust Fluid)

As a Battery Electric Vehicle, the 2022 Tesla Model Y does not have an internal combustion engine and therefore does not utilize Diesel Exhaust Fluid (DEF). DEF is specifically used in diesel vehicles with Selective Catalytic Reduction (SCR) systems to reduce nitrogen oxide emissions.
