Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Cooling system>> Removal and installation of elements of system of cooling>> The sensor of temperature of cooling liquid
Arrangement of sensors of temperature of cooling liquid:
on SOHC engines the sensor is established in a final branch pipe of cooling liquid, on the left side of a head of the block of cylinders;
on RV, PF engines and 2Е the sensor is established on a connecting branch pipe;
on RP engines from a reverse side of a connecting branch pipe;

Fig. 4.7. Pump of system of cooling of the DOHC engine: 1–bolt; 2–generator arm; 3–pulley; 4–bolt; 5–pump of system of cooling; 6–sealing ring; 7–top hose of a radiator; 8–connector; 9–a hose from a heater; 10-a hose to a heater; 11-a hose to a broad tank; 12-the sensor of temperature of cooling liquid; 13-sealing ring; 14-pipe; 15-oil heat exchanger; 16-bottom hose of a radiator; 17-laying; 18-thermostat


on DOHC engines the sensor is established in a final branch pipe (see fig. 4.7 ), on a back surface of a head of the block of cylinders;
on all models electric socket of the sensor of black color.
Removal and installation of the sensor of temperature of cooling liquid carry out in the following order:
– partially merge cooling liquid from cooling system;
disconnect a wire from the negative plug of the storage battery;
– remove the electric tip;
– remove fixing bracket and get the sensor of temperature of cooling liquid from a branch pipe;
– take from a branch pipe a sealing ring of round section;
– at assembly establish a new sealing ring.
Installation of the removed elements make in sequence, return to removal.
