2022 Jeep Cherokee Complete Fluid Specifications

As an ASE-certified master technician, I can tell you firsthand that modern vehicles are highly sensitive to fluid specifications. Gone are the days when you could pour a universal fluid into every reservoir and call it a day. The 2022 Jeep Cherokee is a prime example of a vehicle that demands exact OEM (Original Equipment Manufacturer) specifications to ensure longevity, optimal performance, and warranty compliance.

Below is your comprehensive guide to the exact fluid types, capacities, and Mopar specification numbers for the 2022 Jeep Cherokee, covering all three available engines: the 2.0L Turbo, 2.4L Tigershark, and 3.2L Pentastar V6.

Quick reference

Fluid	Type/Spec	Capacity
Engine Oil (2.0L Turbo)	5W-30 API SP / Mopar MS-13340	5.0 qts (4.7L) with filter
Engine Oil (2.4L)	0W-20 API SP / Mopar MS-6395	5.5 qts (5.2L) with filter
Engine Oil (3.2L V6)	5W-20 API SP / Mopar MS-6395	5.9 qts (5.6L) with filter
Engine Coolant	Mopar 10-Year/150k OAT (MS-90032), Purple	7.2 - 9.3 qts (verify engine)
Transmission Fluid	Mopar ZF 8 & 9 Speed ATF (MS-90030)	~6.3 qts (Service fill varies)
PTU (Transfer Case - 4WD)	75W-90 Synthetic Gear Lubricant GL-5	~0.5 qts (Verify in service info)
Rear Differential (RDM)	75W-90 Synthetic Gear Lubricant GL-5	~0.7 qts (Verify in service info)
Brake Fluid	Mopar DOT 3 Brake Fluid (MS-4574)	Fill to MAX line
Power Steering	Electric Power Steering (EPS)	N/A (No fluid required)
Washer Fluid	Standard All-Weather Washer Solvent	Fill to MAX line
DEF (Diesel)	N/A for 2022 Cherokee (Gasoline only)	N/A

Note: Capacities are approximate. Always verify fluid levels on a level surface using the dipstick or fill/spill plug methods as outlined in OEM service information.

Engine Oil

Choosing the correct engine oil for your 2022 Jeep Cherokee depends entirely on the engine under the hood. Stellantis (Chrysler/Dodge/Jeep/Ram) is very specific about their oil standards.

• 2.0L Turbocharged Engine: Requires a full synthetic 5W-30 engine oil meeting API SP standards and the specific Mopar MS-13340 specification. Turbo engines run exceptionally hot, and using an oil that meets this spec helps prevent Low-Speed Pre-Ignition (LSPI) and turbo coking.
• 2.4L Tigershark Engine: Requires 0W-20 full synthetic oil meeting Mopar MS-6395.
• 3.2L Pentastar V6 Engine: Requires 5W-20 oil meeting Mopar MS-6395. Full synthetic is highly recommended, though conventional or blend is permitted as long as it explicitly carries the MS-6395 certification.

Intervals & Pitfalls: Jeep utilizes an Oil Life Monitor (OLM) that will alert you when it's time to change the oil based on driving conditions. However, never exceed 10,000 miles or 12 months between oil changes, whichever comes first. Never use 10W-30 or 10W-40, as the variable valve timing (VVT) system relies on the exact viscosity of the oil to function properly.

Engine Coolant

The 2022 Jeep Cherokee requires Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology). This meets the MS-90032 specification. Out of the bottle, this factory fluid is purple.

Intervals & Pitfalls: A major pitfall for DIYers and independent shops is mixing OAT coolant with HOAT (Hybrid Organic Additive Technology) or traditional green IAT (Inorganic Additive Technology) coolants. Mixing these incompatible chemical bases will result in the coolant gelling, which clogs the heater core, radiator, and engine water jackets, leading to catastrophic overheating. If you have to top off, strictly use MS-90032 OAT coolant.

Transmission Fluid

All 2022 Jeep Cherokees are equipped with the 948TE 9-speed automatic transmission. This transaxle requires a highly specific fluid: Mopar ZF 8 & 9 Speed ATF, which meets the MS-90030 standard.

Intervals & Pitfalls: Jeep technically considers this transmission "fill for life" under normal operating conditions. However, as a master technician, I strongly recommend a fluid drain-and-fill every 60,000 miles, especially if you tow or drive in severe stop-and-go traffic. Never use a "universal" ATF, Dexron VI, Mercon LV, or even Mopar ATF+4. The 9-speed ZF-designed unit has incredibly tight tolerances and unique friction requirements. Using the wrong fluid will result in harsh shifting, shuddering, and eventual clutch pack failure. Checking the fluid requires a special dipstick tool and a scan tool to verify transmission temperature—it is best left to a professional.

Power Transfer Unit (PTU) & Rear Driveline Module (RDM)

If you have a 4x4/AWD Cherokee, your vehicle utilizes a PTU (similar to a transfer case but for a transverse engine layout) and an RDM (Rear Driveline Module/Differential).

Both units take 75W-90 Synthetic Gear Lubricant meeting API GL-5 specifications. The capacities are very small (less than a quart each).

Intervals & Pitfalls: Because the fluid capacity is so low, these fluids work very hard. They should be inspected at 20,000-mile intervals and changed every 40,000 to 60,000 miles, or more frequently if driven in deep water or off-road. Do not add Limited Slip Differential (LSD) friction modifiers unless specifically directed by the OEM service manual for your exact trim package (like the Trailhawk with the locking rear differential), as it can upset the precise mechanical grip needed in standard AWD systems.

Brake Fluid

The braking system requires DOT 3 brake fluid meeting the Mopar MS-4574 standard. DOT 4 is also acceptable if DOT 3 is unavailable, but do not mix them if you can avoid it, and absolutely never use DOT 5 (silicone-based) fluid, which will destroy the ABS module seals.

Intervals & Pitfalls: Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time. This moisture lowers the boiling point of the fluid, causing a spongy pedal during hard stops, and rots brake lines from the inside out. Flush your brake fluid every 2 years or 30,000 miles, regardless of mileage.

Power Steering, Washer Fluid, & DEF

• Power Steering: The 2022 Jeep Cherokee utilizes an Electric Power Steering (EPS) rack. There is no power steering pump, no reservoir, and therefore no power steering fluid to check or change.
• Washer Fluid: Use any quality all-weather windshield washer solvent. If you live in a cold climate, ensure the fluid is rated for sub-freezing temperatures to prevent the washer reservoir and lines from cracking.
• DEF (Diesel Exhaust Fluid): The 2022 Jeep Cherokee was only offered with gasoline engines. Therefore, DEF is not applicable.
