5.16. Radiator fan thermal sensor



At installation of the thermal sensor use a new sealing ring.


Termodatcha arrangement of turning on of the fan of a radiator on models of 2,0 l of SOHC (bottom view)

1. The thermal sensor of the fan of a radiator is installed in the bottom right corner of a radiator (see the drawing).
2. Check working capacity термодат Chick of the radiator fan. The fan has to turn on at excess of working temperature of the engine, that is several minutes prior to an entrance of an arrow of the index of temperature of the engine to the red sector. If the fan does not turn on, remove wires from the thermal sensor, connect them among themselves and include a zazhig ny. If the fan starts working after that probably Chick who is subject to replacement failed термодат. In case the fan still does not work, check whether tension to the thermal sensor moves. If tension on termodatch ке is absent, perhaps, damage of wires, or the fuse fused.
3. Remove a weight wire from the accumulator, then disconnect the electric socket from the radiator fan thermal sensor.
4. Merge cooling liquid from the cooling system.
5. Unscrew the radiator fan thermal sensor from a radiator and remove condense a telny ring.


1. Installation is made in the sequence, the return to removal. At installation of the thermal sensor use a new sealing ring. Fill in cooling liquid in the cooling system.
2. In conclusion start the engine, warm up it up to the normal working temperature and check operability of the fan of a radiator.
