What coolant goes in a 2016 Dodge Dart?

The 2016 Dodge Dart typically uses Dex-Cool long-life coolant (orange) that meets Chrysler’s specifications. Use a 50/50 premixed mix with distilled water or a Mopar-approved coolant that meets Chrysler MS-9769; avoid mixing with green or conventional coolants.

Approved coolant options for the Dart

To identify safe choices, look for products that explicitly meet Chrysler MS-9769 (Dex-Cool) or FCA/Chrysler specifications and are compatible with the engine family used in the Dart. Mopar’s own premixed Dex-Cool and other reputable brands that certify MS-9769 compatibility are commonly recommended.

• Mopar Antifreeze/Coolant 50/50 Premixed (Dex-Cool, orange) — meets Chrysler MS-9769 and is designed for FCA vehicles.


• Aftermarket OEM-complaint coolant labeled as “MS-9769 compliant” or “Dex-Cool compatible” and formulated as an OAT/HOAT long-life coolant — suitable when the product clearly states compatibility with Chrysler/MS-9769 (verify premixed or concentrate as directed).

Be sure to confirm that the product you buy meets Chrysler MS-9769 or the FCA Dex-Cool specification. Do not mix different coolant technologies, and avoid using green or universal coolants unless the label explicitly states Chrysler/MS-9769 compatibility.

How to check, add, or replace coolant

Follow these steps to safely check and refill the cooling system, ensuring you use the correct Dex-Cool-compatible product.

1. Let the engine cool completely before opening the radiator cap or reservoir to avoid scalding from pressurized coolant.


2. Identify whether your coolant is already Dex-Cool orange or if you’re replacing with an MS-9769-compliant product.


3. If using premixed 50/50, pour directly to the recommended fill line on the reservoir. If using concentrate, mix it with distilled water to a 50/50 ratio as specified by the product.


4. Fill gradually to the full level, then start the engine with the radiator cap off (or cap loosely on a filled reservoir) to circulate air and remove air pockets. Monitor the temperature gauge.


5. Run the engine to operating temperature with the heater on high to help purge air. Check for leaks around hoses, the radiator, and the water pump.


6. Turn off the engine, let it cool, and recheck the coolant level. Top off if needed to the full line with the same Dex-Cool-compatible product.


7. Dispose of any drained or old coolant at an appropriate facility. Do not pour it down a drain or onto the ground.

Following these steps helps ensure proper cooling system performance and avoids mixing incompatible coolants that could reduce protection against overheating and corrosion.

Maintenance intervals and general tips

Dex-Cool-based coolants in FCA vehicles typically carry a longer service interval, but always refer to the Dart’s owner manual for exact guidance. In many markets, a typical interval is around 5 years or 100,000 miles, whichever comes first, for the Mopar Dex-Cool product. If the vehicle has never been serviced or you’re unsure of the coolant history, a complete flush and fill with a Chrysler/MS-9769-compliant coolant is a prudent move.

• Expect a 5-year/100,000-mile maintenance interval for Dex-Cool-type coolants, though always verify with the manual or a dealer.


• Use only coolant that explicitly states MS-9769 compatibility or Mopar/Chrysler approval to maintain corrosion protection and warranty coverage.


• Avoid mixing Dex-Cool with traditional green inorganic coolant or unlisted universal mixes unless the product explicitly states compatibility.


• Regularly inspect the cooling system for leaks, white deposits, or sweet-smelling steam, which can indicate coolant loss or head-gasket concerns.

Sticking to the manufacturer’s specification helps prevent overheating, corrosion, and costly repairs, and keeps the cooling system operating as designed.

Summary

The 2016 Dodge Dart uses Dex-Cool long-life coolant (orange) and should be topped up or replaced with a product that meets Chrysler MS-9769. The simplest, safest option is Mopar’s approved 50/50 premixed Dex-Cool, though MS-9769-compliant aftermarket coolants are acceptable as well. Always use the correct type, mix it to the recommended ratio, avoid mixing with incompatible coolants, and follow the factory maintenance intervals for best results.
