The 2020 Jeep Compass uses Mopar Antifreeze/Coolant Type 2 HOAT in a premixed 50/50 solution, or an equivalent that meets Jeep/Chrysler specifications. Confirm the exact requirement in your owner's manual or on the under-hood label.
The cooling system in the 2020 Compass is designed for ethylene glycol–based coolant that is silicate-free and compatible with FCA/Jeep specifications. While many owners opt for the ready-to-pour premixed version, it’s essential to use a coolant that specifically lists Mopar Type 2 HOAT or an FCA-approved equivalent to ensure proper heat transfer, corrosion protection, and warranty compliance. If you’re unsure, contact a Jeep dealer or trusted mechanic for the correct specification for your market.
Understanding the right coolant for your Jeep
To avoid overheating and costly corrosion-related issues, it’s important to use the exact coolant type approved by Jeep. The Compass uses a modern HOAT formula designed for FCA engines and sealed cooling systems. Here are the key points to keep in mind when shopping for coolant.
- Use Mopar Antifreeze/Coolant Type 2 HOAT or an equivalent that meets Jeep/Chrysler specifications (often labeled WSS-M97B51-A or an FCA-approved standard).
- Choose a premixed 50/50 ethylene glycol–based coolant unless you are mixing your own with distilled water per the manual.
- Do not use universal coolant unless the product explicitly states compatibility with FCA/Jeep vehicles.
- Avoid mixing different coolant brands or formulations, which can reduce protection and alter boiling/freezing behavior.
- Ensure the coolant is silicate-free and suitable for aluminum components commonly used in modern Jeep engines.
Concluding: Following the approved Mopar Type 2 HOAT specification helps preserve cooling performance, prevent damage, and maintain warranty coverage.
How to top off or replace the coolant
Before you begin, make sure the engine is cool and the vehicle is on a level surface. The following steps outline common, safe practices for topping off or refreshing the coolant in a 2020 Compass.
- Open the hood and locate the coolant reservoir; check the level against the Full line on the translucent reservoir.
- Top off with premixed Mopar Type 2 HOAT coolant to the Full line, or drain and replace if performing a full cooling-system service per the manual.
- If draining, locate the radiator drain plug or follow the service procedure to drain and flush, then refill with the correct premixed coolant.
- Run the engine with the heater on high to bleed air from the system, then recheck the level once the engine cools.
- Dispose of old coolant at an approved facility and never pour used coolant down the drain or onto the ground.
Concluding: Proper bleeding, level checks, and using the correct coolant type help maintain cooling performance and prevent overheating.
Where to confirm the exact spec
The precise specification is listed in the owner’s manual and on an under-hood label. If you’re ever unsure, contact a Jeep dealership service department or a qualified mechanic to verify the exact coolant type for your vehicle’s configuration and region.
Summary
For a 2020 Jeep Compass, the recommended coolant is Mopar Antifreeze/Coolant Type 2 HOAT in a premixed 50/50 solution, or an equivalent that meets FCA/Jeep specifications. Use a silicate-free, ethylene glycol–based coolant and avoid mixing different types or using non-approved universal formulas. Always refer to the owner's manual or the under-hood label for the exact specification, and consult a dealer or mechanic if you’re unsure. Regular checks of the coolant level and condition help protect the engine and keep the cooling system functioning properly.
