The correct coolant is Mopar Extended Life Coolant (ELC), a long-life HOAT/OAT-type coolant sold as a 50/50 premixed solution that meets Chrysler/Dodge specifications for the 2012 Ram 1500. Use only coolant labeled as Chrysler-approved for RAM/Dodge engines and avoid mixing with non-approved formulations.
In this article, we look at which coolants are acceptable, how to identify the right product, and how to replace or top off coolant to keep the cooling system in good working order. We’ll also cover common maintenance tips and pitfalls relevant to a 2012 Ram 1500.
Recommended coolant options for a 2012 Ram 1500
To ensure compatibility and long-term protection, choose a coolant that is explicitly labeled as Chrysler-approved for Dodge/Chrysler vehicles and that is a long-life HOAT/OAT formulation. The Ram 1500’s cooling system is designed for this type of coolant, and using the correct product helps prevent corrosion and deposits.
- Mopar Extended Life Coolant (ELC) — premixed 50/50 formulation designed for Chrysler engines
- Any Chrysler-approved HOAT/OAT coolant that is explicitly labeled as suitable for Dodge/Chrysler vehicles
- Follow the product label and owner’s manual to confirm compatibility and intervals; avoid using coolant not labeled for Chrysler vehicles or universal coolants unless the label explicitly states compatibility
In short, the safe bet is Mopar ELC or another Chrysler-approved long-life HOAT/OAT coolant. If in doubt, consult the owner's manual or a trusted mechanic before proceeding.
How to replace or top off coolant
The following steps outline a typical drain-and-fill or top-off procedure for a 2012 Ram 1500. Always ensure the engine is completely cool before starting any work, and dispose of old coolant properly.
- Park on level ground and let the engine cool fully. Open the radiator cap only after the system is cool.
- Place a drain pan beneath the radiator drain valve and open it to drain the old coolant from the radiator and engine block. Allow all fluid to drain.
- If performing a flush, follow your manual’s recommended flush procedure and then re-drain the system.
- Close the drain valve. Remove the radiator cap and slowly fill the system with 50/50 Mopar Extended Life Coolant (or other Chrysler-approved HOAT/OAT coolant) until the correct level is reached.
- With the cap off, start the engine and allow it to reach operating temperature to purge air from the system. Keep adding coolant as needed to maintain the proper level while watching for bubbling or leaks.
- Once the engine reaches normal temperature and the level stabilizes, replace the radiator cap and perform a final check of all hoses and fittings for leaks. Recheck the coolant level when the engine is cold again and top off if necessary.
Regularly inspecting the cooling system and maintaining the correct coolant level helps prevent overheating and corrosion. If you’re not comfortable performing a drain-and-fill, seek a professional service.
Maintenance note and safety considerations
Always use coolant that is explicitly labeled as Chrysler-approved for Dodge/Chrysler vehicles. Mixing coolant types can cause chemical reactions, varnish, and reduced cooling efficiency. If you’ve previously used a different coolant, a complete flush is often recommended before refilling with Mopar ELC or any Chrysler-approved product.
Summary
For a 2012 Dodge Ram 1500, the recommended coolant is Mopar Extended Life Coolant (ELC) or another Chrysler-approved HOAT/OAT long-life coolant. Use a 50/50 premixed formulation, avoid mixing with non-approved coolants, and follow proper bleeding and maintenance intervals. If you’re unsure about the correct product or procedure, consult the owner's manual or a qualified mechanic to ensure your cooling system stays protected and efficient.
