Yes — you can, but only if you choose a Prestone formulation that is compatible with Chrysler/HOAT cooling-system requirements and you follow proper replacement procedures. The Dodge Dart (model years around 2013–2016) relies on a silicate‑free HOAT-type coolant, so selecting a Prestone product labeled as Chrysler/Mopar-compatible and avoiding mixing incompatible chemistries is essential.
What your Dodge Dart needs in coolant terms
Most Mopar-based cooling systems, including those in the Dodge Dart, are designed for Hybrid Organic Acid Technology (HOAT) coolants that are silicate-free and colored orange. The official maintenance interval for many Chrysler/Fiat group vehicles is roughly 5 years or 100,000 miles, though you should confirm the exact specification in your owner's manual. If you are unsure about which chemistry your Dart uses (Dex-Cool, HOAT, or another variant), consult the manual or a dealer to avoid mismatches. Mixing different coolant chemistries can cause deposits, corrosion, or reduced protection.
Common cautions about mixing
Do not mix green conventional coolant with Dex-Cool or other HOAT formulations unless the product you’re using explicitly states it is compatible with those chemistries. If you’re switching to Prestone from another brand or chemistry, a full system flush is often the safest option before refilling with a single compatible Prestone product.
Choosing the right Prestone product for a Dodge Dart
To minimize risk, look for Prestone products that clearly state compatibility with Dex-Cool, HOAT, and Chrysler/Mopar systems, and choose the 50/50 premixed variant or a concentrate that you dilute to 50/50 according to the label. Using a product designed for all major automotive coolants helps ensure proper corrosion protection and long-term reliability.
- All-Vehicle formulations labeled as compatible with Dex-Cool, HOAT, and Chrysler/Mopar systems (typically available in 50/50 premixed or ready-to-use forms).
- Dex-Cool–compatible formulations specifically marketed for Dex-Cool systems, used when the Dart’s prior fill is Dex-Cool and you perform an appropriate system assessment or flush.
- Concentrates that you dilute to a 50/50 mixture, useful when performing a full system refill or flush and you need precise control over the final coolant concentration.
Choosing the right Prestone product helps protect against corrosion, deposits, and improper freeze/boil protection, while simplifying maintenance over the life of the cooling system.
How to replace coolant in a Dodge Dart
When it’s time for a coolant replacement, follow these general steps. If you are unsure about any step, consult a qualified mechanic or your vehicle’s service manual for model-specific guidance and capacities.
- Gather supplies: a Prestone coolant that matches Chrysler/HOAT compatibility, distilled water if using concentrate, a drain pan, funnel, rags, gloves, and basic hand tools.
- Ensure the engine is cool and the vehicle is on a level surface. Open the radiator cap only after the engine has cooled to avoid scalding.
- Drain old coolant from the radiator drain plug and any engine block drains into the drain pan.
- Optionally flush the system with distilled water or a dedicated radiator flush product to remove old deposits and ensure compatibility with the new coolant.
- Refill with a 50/50 mix of Prestone coolant and distilled water as specified on the product label, filling through the radiator neck or overflow reservoir until at the correct level.
- Bleed air from the cooling system if your Dart requires a specific bleed procedure, then run the engine to operating temperature with the radiator cap off (or per manual) until the thermostat opens and the level stabilizes. Top off as needed.
- Check for leaks and properly reattach all caps. Replace the radiator cap, drive for a short interval, and recheck the coolant level when the engine is cool again.
Keep an eye on the coolant level over the following days and weeks. If you notice overheating, leaks, or a sweet smell indicating a leak, stop driving and seek service promptly.
Maintenance tips and practical guidance
Record the service, stay within the recommended interval, and ensure you always use a single compatible chemistry for the entire system. If your Dart previously used a different coolant type, a full system flush before switching to Prestone is generally advised to prevent incompatibility issues.
Summary
In short, you can use Prestone coolant in a Dodge Dart as long as you choose a product that is explicitly compatible with Chrysler/HOAT systems, avoid mixing incompatible chemistries, and follow proper replacement and bleeding procedures. Always verify the exact specification in your owner's manual, and consult a technician if you’re unsure about your vehicle’s cooling-system chemistry.
