Alleged overheating problem or electrical fault in a 2.2 lt Daewoo Leganza.

i have a daewoo espero: solved it like this, acroos the two wires leading from the engine temperature switch ,connect a 450 0hm resistor. Temperature will stabilise at half the temperature gauge all the time. Reason: the temperature switch is a variable resistir that changes value as the engine temperature changes. The fan is a 2 speed fan which changes speed ( hence the rate of cooling)

had same prob in mine,.....your thermo switch has gone. Once that goes your thermo fans dont turn on

you require a teremisate i have and 01 daewoo legnza sd/ cdx and the first thing i had to put in int was a thermisate sensor now i require some extra work cuz i have a short and no idea where these cars a great if you have the time and money to put in em but they are all sensors and wires hope that helps ps my prevous veichial was a 1989 ford bronco xlt and i pretty much replaced everything in it and knew how to put in everything in it with this car cuz its newer and has all the bells and whishles i have no idea where to put anything or what any of it does i feel real stupid becuase im a young woman and when i take it to the macanic i feel like their laughing at me lol hope that helps
