The coolant P35, is a water-glycol mixture consisting of 35 % "Fragol Zitrec FC" concentrate
and 65 % demineralized/distilled water. To top up or fill the cooling system, it is only per-
mitted for the named concentrates to be used at the specified ratios.
CAUTION
Damage to the motor due to incorrect concentrate or mixing ratio!
The motor may be destroyed if other concentrates are used! If the mixing ratio differs,
this means that frost and corrosion protection is not guaranteed! Use only the concen-
trates listed in the ratio 35:65.
