COROLLA 1992 engine overheating 1992

Friends I have the next query to see if they can help, I have had problems of engineing of the engine of my corolla 1992, when I have the car on the car the car the temperature rises to the maximum and does not activate the electro of the engine, when I have the air conditioning activated it works normally by driving the two electro and working the electro of the engine in its two speeds, I have already checked fubles, and everything is in perfect condition. The temperature valve, or will be some false contact that could work the fault, I hope they can help me, greetings and thanks in advance.

Hello for the symptoms and what you explain in this forum the problem of the overheating of your car has to do with the temperature sensor of the electrovilers almost always goes near the hose of the return of the refrigerant to the radiator near the thermostat (you have a test; if you locate it disconnects and the electromotor must work)

Indeed, friend, I already did that test with the off the air off, I disconnect the connection to the temperature valve and the electro turns on, I turn it back and turn off, but it continues to present the failure that it is not automatically activated by temperature, unlike when it has the air on it makes all its normal changes and not requalier, greetings and thanks for your quick response

Hello friend, you have the following ... you say that you disconnected the sensor that electrovalkers activate and they were activated ... then easy ... Change that sensor since it is not sending the signal to the temperature due to the fans ... This sensor is also called Termoswicht. Surely friend changes this sensor and your problem will leave ... and for security the derivation valve called thermostat also changes ... I hope your answer and know how you ... a pleasure to help you..Asaludos ..
