Vehicle data The antifreeze/corrosion inhibitor concentration in the engine cooling system should: Rbe at least 50%. This will protect the engine 281 cooling system against freezing down to approximately -35 ‡ (-37 †). Rnot exceed 55% (antifreeze protection to -49 ‡ [-45 †]); heat will otherwise not dissipate as effectively. If the coolant level is too low, MB 325.0 antifreeze/corrosion inhibitor should be added. Have the engine cooling system checked for possible leaks.
