The intake manifold ‘s air may be preheated by the electrical heater as well as by coolant. As the
coolant’s temperature is lower than 60
°
, the electronic heater will be energized to facilitate the cold
starting.
The electrical heater’s energizing or deenergizing is controlled by the intake preheating switch and relay.
The intake preheating switch is installed in the M22 bolt hole in the thermostat seat(with the hole plugged by
plug screw for carburetor engine). The intake preheating switch’s operation parameters:
