⚠️ Critical Disclaimer: Do Not Mix Coolants

It is crucial that you do not mix different colors or technologies of Mopar coolant (e.g., OAT with HOAT). Mopar coolants are formulated differently based on color and technology. Mixing them can lead to chemical incompatibility, which may cause your coolant to gel, clog your cooling system, and result in severe engine damage. Always check your owner's manual to ensure compatibility.
