How do you replace the thermostat in Daewoo Lanos 2000 Model?
The same as you would in any other car. Drain the old coolant out, replace the thermostat, flush the system, install a 50/50 mix of the coolant recommended in your owner's manual. There is a drain plug on the drivers side under the car, its right under the trans cooler lines, 2 lines to be exact, you can just unscrew it by hand because there is like a handle to it!!!
