The 2019 Jeep Grand Cherokee, a popular mid-size SUV known for its blend of off-road capability and on-road comfort, requires specific fluids to maintain its performance and longevity. Using the correct fluids adhering to manufacturer specifications is paramount to prevent premature wear, maintain warranty coverage, and ensure optimal operation. This guide provides a comprehensive overview of all factory-spec fluids for the various engine and drivetrain configurations available in the 2019 Grand Cherokee.

Engine Oil

Engine oil is the lifeblood of your engine, providing lubrication, cooling, and cleaning properties. The 2019 Grand Cherokee was offered with several engine options, each with specific oil requirements.

For the 3.6L Pentastar V6 and 5.7L HEMI V8 engines, the factory-recommended engine oil is SAE 5W-20, meeting API SN or SP service categories and Mopar Material Standard MS-6395. The 3.6L V6 typically holds approximately 5.9 quarts, while the 5.7L HEMI holds about 7.0 quarts (both capacities include a filter change). The oil change interval is generally every 10,000 miles or 12 months, whichever comes first, under normal driving conditions. However, the onboard Oil Change Indicator System should always be followed, as it monitors driving conditions and adjusts the interval accordingly. Using an oil that does not meet the MS-6395 specification can lead to increased engine wear, reduced fuel economy, and potential issues with variable valve timing (VVT) components.

SRT and Trackhawk models, equipped with the high-performance 6.4L HEMI V8 (SRT) or 6.2L Supercharged HEMI V8 (Trackhawk), require a different specification: SAE 0W-40, meeting API SN or SP service categories and Mopar Material Standard MS-12633. These engines demand a more robust oil to handle the extreme temperatures and pressures generated. Capacity for these engines is approximately 7.0 quarts. Due to the high-performance nature, more frequent oil checks are recommended.

For the 3.0L EcoDiesel V6, a specific low-ash oil is required to protect the diesel particulate filter (DPF) and other emissions components. The recommended oil is SAE 5W-40, meeting API CJ-4 or CK-4 service categories, ACEA C3, and Mopar Material Standard MS-10902. The capacity is around 8.5 quarts. It is critical to use only oils that meet these specifications, as incorrect oil can quickly clog the DPF, leading to costly repairs.

Engine Coolant

Maintaining the correct engine temperature is crucial, and the proper coolant plays a significant role. The 2019 Jeep Grand Cherokee utilizes Organic Acid Technology (OAT) coolant, specifically Mopar MS-90032. This coolant is typically purple or pink in color. The total system capacity varies by engine but is generally around 14 quarts. The recommended service interval for OAT coolant is typically 10 years or 150,000 miles, whichever comes first. It is extremely important not to mix OAT coolant with conventional HOAT (Hybrid Organic Acid Technology) or IAT (Inorganic Acid Technology) coolants, as this can lead to gel formation, corrosion, and severe damage to the cooling system and engine. Always use distilled water if mixing concentrate, though pre-mixed 50/50 solutions are readily available and recommended.

Transmission Fluid

The 2019 Grand Cherokee, across most engine variants, is equipped with a ZF 8-speed automatic transmission (8HP70 or 8HP75). These transmissions require a highly specialized fluid. The factory-fill fluid is ZF Lifeguard 8, or its Mopar equivalent, Mopar ZF 8-Speed ATF, which meets Mopar Material Standard MS-9602. The capacity for a drain and fill is typically 5-7 quarts, while the total system capacity is around 9-10 quarts. It is crucial to use only this specified fluid. Universal ATFs or fluids not explicitly approved for ZF 8-speed transmissions can lead to shifting issues, premature wear, and transmission failure. Transmission fluid is often considered "fill-for-life" by some manufacturers, but for optimal longevity, particularly under heavy towing or severe driving conditions, a fluid and filter change between 60,000 and 100,000 miles is often recommended.

Transfer Case Fluid

For 4WD and AWD Grand Cherokees, the transfer case requires specific lubrication. Both the single-speed and two-speed (Quadra-Trac II and Quadra-Drive II) transfer cases in the 2019 Grand Cherokee utilize Mopar ATF+4 automatic transmission fluid. The capacity for most transfer cases is approximately 1.5 quarts. Ensure you are using genuine Mopar ATF+4 or an officially licensed equivalent. The service interval for the transfer case fluid is typically 60,000 miles under normal conditions or more frequently with heavy off-road use or towing.

Differential Fluid

Both the front and rear differentials require specific gear oils.

For 3.6L Pentastar V6 and 5.7L HEMI V8 models, both the front and rear differentials typically use SAE 75W-85 GL-5 gear oil, meeting Mopar Material Standard MS-9020. Capacities are usually around 1.0-1.2 quarts for each differential. Some models may have a limited-slip differential (LSD) in the rear, which might require an additional friction modifier. However, many modern GL-5 LSD-specific oils already contain the necessary additives. Always verify your specific differential type and fluid requirements in your owner's manual.

For SRT and Trackhawk models, the differentials require heavier-duty lubrication. The front differential uses SAE 75W-90, meeting Mopar Material Standard MS-9921, with a capacity of approximately 1.3 quarts. The rear differential on these performance models uses SAE 75W-140, also meeting Mopar Material Standard MS-9921, and requires an additional limited-slip friction modifier due to the high-performance limited-slip differential. The capacity is around 1.5 quarts. Neglecting the friction modifier for LSDs can lead to chatter, noise, and accelerated wear. Differential fluid service intervals are typically around 60,000 to 80,000 miles, or more frequently if towing or off-roading.

Brake Fluid

The 2019 Grand Cherokee utilizes hydraulic brake fluid. The recommended specification is DOT 3 or DOT 4 brake fluid. DOT 4 offers a higher wet boiling point, which can be beneficial for performance driving or heavy use. Never use DOT 5 (silicone-based) fluid in a system designed for DOT 3 or 4, as it is incompatible and can cause seal damage. Brake fluid is hygroscopic, meaning it absorbs moisture over time, which lowers its boiling point and can lead to corrosion in the brake system. It's generally recommended to flush and replace brake fluid every 2-3 years, or according to your owner's manual.

Power Steering Fluid

The 2019 Grand Cherokee utilizes an electro-hydraulic power steering system (EHPS) for most variants, which does not use a traditional, user-serviceable power steering fluid reservoir. The system is sealed and typically only serviced by specialized technicians if a component fails. Therefore, there is no conventional power steering fluid to check or change.

Washer Fluid

The windshield washer system requires a dedicated washer fluid. While many generic options exist, it's best to use a high-quality all-season washer fluid, ideally a concentrated formula mixed with water or a pre-mixed solution. Mopar offers its own Mopar Windshield Washer Concentrate/Fluid. The reservoir capacity is typically around 1 gallon. Using plain water is not recommended as it can freeze in colder temperatures and does not contain the necessary detergents to effectively clean the windshield.

Diesel Exhaust Fluid (DEF) – 3.0L EcoDiesel

For 3.0L EcoDiesel V6 models, Diesel Exhaust Fluid (DEF) is essential for the Selective Catalytic Reduction (SCR) system, which reduces NOx emissions. DEF must meet the ISO 22241 standard and be API DEF certified. The DEF tank in the 2019 Grand Cherokee EcoDiesel holds approximately 8.5 gallons. It is crucial to use only high-quality DEF and to avoid contamination with other fluids. DEF has a shelf life, so always check the manufacturing date. Never use water or any other fluid in the DEF tank, as this will damage the SCR system and lead to costly repairs. The vehicle will provide warnings well in advance when the DEF level is low, and if allowed to run out, the engine's performance will be severely limited until it is refilled.
