connecting valve - heating throttle tube, 2 - the supply line - heating throttle tube, 3 - Sensors - coolant temperature, 4 - Channel connectivity - reusable tube heat exchanger heating the passenger compartment, 5 - Channel connection - the line feeding the heat exchanger system heating the interior of 6 - to connect - the thermostat wiring harness connector from the threedimensional characteristics of the adjusting, 7 - Channel connection reusable tube radiator
90 ° C - the level of coolant temperature to medium and full loads. It is regulated by electrically heating element in the extension element at a signal from the temperature control system in the engine management system, control is a function of engine speed, load, gear selection and ambient temperature.
The range of coolant temperature to 105 ° C (idle speed and average load) is regulated by a thermostat with an element of expansion. The range of coolant temperature to 95 ° C (medium and full load) is regulated by an additional electric heater element in the expansion. The heater is powered by a system of temperature control and stirs an extension element, so that the thermostat open at higher temperatures. Ranges coolant temperature regulated as a function of engine speed, engine load, gear selection and ambient temperature.
Features
Reducing weight by using plastic. Improved cooling by optimizing the circulation of coolant. No exhaust gas recirculation valve. Coolant temperature is regulated by engine management system.
Gasoline engine Z 18 XER DOHC-I is equipped with electronic engine control system Simtec 75.1 EMS production of Siemens VDO. Engine Management System provides adjustment of camshafts and control the temperature regime of the engine. To perform these functions, increased computing power and installed additional sensors.

Improved design of the control unit, located on the module inlet. Used a new crankshaft sensor and two camshafts are driven control valve inlet and exhaust valves. In addition, installed a new throttle body pipe is heated from the periphery of the coolant. The electronic engine control module Simtec 75.1 located on the housing intake manifold and secured by four threaded bushings.
