Your service center can advise you on which

engine has cooled down.

Coolant

Coolant consists of half water and half additive.
Not all commercially available additives are suit-

engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
