What's the what type of coolant for chrysler 300?

I recommend using Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology) that meets the requirements of FCA Material Standard MS. 90032 on a Chrysler 300. Replace coolant for the engine at 100,000 miles or ten years. Over time, engine coolant loses its anticorrosive properties and lubricating ability.Over time, Your radiator coolant can cause radiator corrosion, generating rust that You do not want in Your car's radiator or engine. Signs that an immediate radiator flush is necessary to include coolant leaking underneath Your car and hearing a grinding engine noise. Other signs of a sick cooling system are if You smell antifreeze or if the car overheats too easily.
