LIQUID-COOLED MODELS
All models included in this book, except Z 440
models, are equipped with a liquid-cooling sys-
tem to maintain the temperature of the engine.
The liquid-cooling system is a closed system that
consists of a pressure cap, coolant pump, coolant
reservoir tank, heat exchanger and hoses. See
