The 2012 Dodge Avenger uses Dex-Cool orange long-life coolant, or an equivalent Dex-Cool-compatible OAT (organic acid technology) coolant that meets Chrysler specifications.
For best results, use a Dex-Cool–type coolant (orange) that is designed for Chrysler/Dodge applications. Options include Mopar Dex-Cool or a third‑party Dex-Cool–compatible product labeled for use in Chrysler vehicles. Avoid green traditional coolant or universal formulas unless the label explicitly states Dex-Cool/OAT compatibility for Chrysler vehicles. Coolant should be used in a 50/50 premixed solution or mixed with distilled water per the product instructions.
Recommended coolant types
Here are the coolant options that meet the vehicle’s requirements.
- Dex-Cool orange long-life coolant (the OEM standard for many Chrysler/Dordge applications).
- Dex-Cool–compatible long-life OAT coolant that explicitly states compatibility with Chrysler/Dodge vehicles.
- Premixed 50/50 Dex-Cool or equivalent OAT coolant designed for Chrysler applications.
When selecting coolant, ensure it is silicate-free and labeled for Dex-Cool or Chrysler OAT compatibility. Do not mix Dex-Cool with green or other non-Dex-Cool formulations, as mixing can reduce protection and lead to deposits.
How to verify and replace the coolant
Before attempting a check or replacement, gather the right supplies and follow a careful procedure to avoid burns or spills.
- Park on a level surface, engine cool, and open the hood. Identify the coolant reservoir and radiator drain points per the owner's manual.
- Inspect the coolant color. It should be orange (Dex-Cool or compatible OAT). If you see a mixture of colors, have the system flushed and refilled with the correct type.
- Drain the old coolant (if performing a complete replacement) and thoroughly flush the cooling system if advised by the manual or a technician.
- Refill with a 50/50 premixed Dex-Cool or a compatible Dex-Cool OAT coolant, filling to the MAX line on the reservoir or radiator neck as specified.
- Start the engine and bring it to operating temperature with the heater on high to circulate the coolant. Check for leaks and recheck the level once cooled and rechecked under pressure.
- Properly dispose of the old coolant in accordance with local regulations and recycle or reuse containers as required.
After replacement, monitor the coolant level and temperature gauge. If you’re unsure about the correct product or procedure, consult the owner’s manual or contact a Chrysler dealer or qualified technician.
Summary
The 2012 Dodge Avenger requires Dex-Cool orange long-life coolant or a compatible Dex-Cool–type OAT coolant designed for Chrysler vehicles. Use a 50/50 premixed solution or concentrate mixed with distilled water as directed, avoid green or non‑Dex-Cool formulas, and follow the vehicle’s maintenance schedule for replacements. When in doubt, verify the exact specification in the owner's manual or with a dealership.
