5.6.1. Check


Arrangement of the thermal sensor of turning on of the fan of a radiator in the lower tank of a radiator on models with four-cylinder engines

The control of the fan is made by the thermal sensor installed in a radiator.
On the engine 1MZ-FE V6 thermal sensors No. 1 (A) and No. 2 (B) are located on a thermostat casing.

Check of resistance of thermal sensors on the engine 1MZ-FE V6
On the cold engine resistance of the sensor No. 1 has to be equal 0.

Check of serviceability of the engine of the fan of a radiator giving of tension on it additional wires from the accumulator

The fan has to turn on at excess of working temperature of the engine, that is some minutes prior to an entrance of an arrow of the index of temperature of the engine to red sector. If the fan does not turn on, remove wires from the thermal sensor, connect them among themselves and include ignition. If the fan after that starts working probably the thermal sensor which is subject to replacement failed. In case the fan still does not work, check, whether tension to the thermal sensor moves. If tension on the thermal sensor is absent, perhaps, damage of wires, or the fuse fused. If tension moves, check reliability of connection with the mass of the second wire of the sensor. If termodat Chick and an electrical wiring in a good shape it is, so possible, the fan electric motor is damaged. The electric motor can be checked by giving of tension for it a dopolnitel ny wires from the accumulator.
