THERMOSTAT OPERATION Operation
1. At warming upValve closes until temperature of coolant reaches to 85 °C.
B. From Radiator
C. From Crankcase
D. To Crankcase
2. At partial opening. Valve opens partially as temperature of coolant is maintained between 85-100 °C.
3. At full opening. Valve opens full as temperature of coolant is more then 100 °C.
