Engine Oil

The 2020 Jeep Cherokee comes with a choice of two primary engines: the 2.4L Tigershark MultiAir 2 I4 and the 3.2L Pentastar V6. It is crucial to use the correct engine oil specification for your specific engine to ensure proper lubrication and longevity. Always verify the exact specification in your owner's manual.

For the 2.4L Tigershark MultiAir 2 engine, the recommended engine oil is 5W-20 meeting API SP or latest specification. The oil should be marked with the API "Starburst" certification symbol. Some earlier models might have called for a different spec, so always double-check your owner's manual. Capacity is approximately 5.9 - 6.0 quarts with a filter change.

For the 3.2L Pentastar V6 engine, the recommended engine oil is 0W-20 meeting API SP or latest specification. Look for the API "Starburst" certification symbol. Capacity is approximately 5.9 - 6.0 quarts with a filter change.

Common Pitfalls: Never use an oil with a viscosity or specification not explicitly recommended by Jeep. Using the wrong oil can lead to premature engine wear, reduced fuel economy, and potential warranty issues. Always change your oil and filter according to the manufacturer's recommended service intervals, typically every 10,000 miles or 12 months, whichever comes first, under normal driving conditions. Severe duty conditions (towing, extreme temperatures, dusty environments) will require more frequent changes.

Engine Coolant

The 2020 Jeep Cherokee utilizes a specific OAT (Organic Acid Technology) coolant. The factory fill is Mopar Antifreeze/Coolant, Pre-mixed 5 Year/100,000 Mile Formula, which is typically purple in color. The OEM specification for this coolant is MS-90032. This is a long-life coolant designed for extended service intervals.

Common Pitfalls: Do NOT mix different types of coolants (e.g., OAT with HOAT or IAT). Mixing incompatible coolants can lead to chemical reactions that form precipitates, clog the cooling system, and cause severe engine damage. Always flush the system thoroughly if you need to switch coolant types or if the incorrect type has been introduced. Always use a 50/50 mix of concentrated coolant and distilled water, or simply use the pre-mixed solution. Never use tap water as minerals can cause deposits. The typical service interval for this OAT coolant is 10 years or 150,000 miles, but always refer to your owner's manual for the most accurate information.

Transmission Fluid

The 2020 Jeep Cherokee can be equipped with different automatic transmissions, most commonly the ZF 9HP-series 9-speed automatic transmission. It is absolutely critical to use the correct fluid for your specific transmission.

For the ZF 9HP-series automatic transmissions, the required fluid is Mopar ZF 8&9 Speed ATF or an equivalent fluid that meets ZF P/N S671 090 312. Never use "universal" or generic ATF. Some model variants may also specify Mopar SP-IV automatic transmission fluid Mopar P/N 68171668AB. It is imperative to verify the exact fluid type in your owner's manual or OEM service information, as using the wrong fluid can cause catastrophic transmission failure.

Common Pitfalls: Transmission fluid is often marketed as "lifetime fill" by some manufacturers. However, for optimum longevity and performance, it is highly recommended to service the transmission fluid and filter (if applicable) at regular intervals, especially under severe driving conditions (towing, frequent stop-and-go traffic). Consult a trusted professional for severe duty service intervals, typically every 60,000 to 80,000 miles. Always use genuine Mopar fluid or an approved equivalent meeting the exact OEM specification.

Transfer Case Fluid (if 4WD/AWD)

If your 2020 Jeep Cherokee is equipped with 4WD or AWD, it will have a transfer case. The fluid requirements can vary depending on the specific transfer case system (e.g., Active Drive I, Active Drive II, Active Drive Lock).

Many 2020 Jeep Cherokee transfer cases require Mopar Transfer Case Fluid that meets ZF P/N S671090312. Some earlier or specific transfer case designs might call for Mopar ATF+4. Always refer to your owner's manual or OEM service information to confirm the exact fluid type and capacity for your specific transfer case.

Common Pitfalls: Transfer case fluid is often overlooked. Regular maintenance is crucial, especially if you engage in off-road driving, towing, or frequently drive in challenging conditions. Check your owner's manual for recommended service intervals, typically every 60,000 miles for normal use, with shorter intervals for severe duty.

Differential Fluid (Front and Rear)

The 2020 Jeep Cherokee, if equipped with 4WD/AWD, will have both a front and a rear differential. The fluid specifications are generally consistent, but it's always best to verify.

For both the front and rear differentials, the recommended fluid is Mopar Gear & Axle Lubricant 75W-90, which meets API GL-5 specification. For models equipped with a Limited Slip Differential (LSD), a friction modifier additive might be required in the rear differential. Some Mopar 75W-90 fluids come with the friction modifier already included, but always check the product label or consult your owner's manual.

Common Pitfalls: Just like transfer cases, differentials are often neglected. Regular fluid changes are crucial for preventing wear and ensuring smooth operation, especially if you tow or drive off-road. Check your owner's manual for recommended service intervals, typically every 60,000 miles for normal use, with shorter intervals for severe duty. Using the wrong viscosity or a non-API GL-5 fluid can lead to premature wear and noise.

Brake Fluid

The 2020 Jeep Cherokee requires Mopar DOT 3 or DOT 4 Brake Fluid. Both are glycol-ether based fluids. While DOT 4 has a higher wet and dry boiling point than DOT 3, they are generally compatible. However, if your system calls for DOT 4, it is best to use DOT 4 to maintain optimal braking performance.

Common Pitfalls: Never use DOT 5 (silicone-based) brake fluid in a system designed for DOT 3 or DOT 4, as they are not compatible and can cause severe damage to the braking system components. Brake fluid is hygroscopic, meaning it absorbs moisture over time, which lowers its boiling point and can lead to corrosion in the brake lines and calipers. It is recommended to flush and replace your brake fluid every 2-3 years, or as specified in your owner's manual.

Power Steering Fluid

The 2020 Jeep Cherokee is equipped with an Electric Power Steering (EPS) system. This means there is no traditional hydraulic power steering fluid to check or change. The system is electronically assisted.

Washer Fluid

For the windshield washer system, any good quality Mopar Windshield Washer Fluid or equivalent fluid designed for automotive use is appropriate. Choose a formula suitable for your climate, such as an all-season or de-icing formula if you live in a colder region.

DEF (Diesel Exhaust Fluid)

The 2020 Jeep Cherokee does not offer a diesel engine option for the North American market, therefore, DEF (Diesel Exhaust Fluid) is not applicable to these vehicles.
