tion in the engine cooling system should:
Rbe at least 50%. This will protectthe engine
cooling system against freezin gdown to
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreez eprotection down
to -49 ‡[-45 †]). Otherwise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor in accordanc ewith MB Spec-
ifications for ServiceP roducts 310.1.
iWhen the vehicle is first delivered, it is filled
with acoolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked at specified intervals
at aq ualified specialist workshop.
The engine cooling system is filled with coolant
at the factor ywhich contains antifreeze/corro-
sion inhibitor that ensures protection down to
