Toyota RAV4>> The monitoring system and decrease in toxicity of the fulfilled gases>> Gauges and valves of system of injection of fuel (EFI)>> Replacement of the gauge of temperature of a cooling liquid (ECT)
The gauge of temperature of a cooling liquid represents the thermoresistor, i.e. the resistor which resistance changes depending on temperature. At reduction of temperature resistance of the gauge increases and on the contrary (specifications see).
Replacement of the gauge of temperature of a cooling liquid make on the cold engine as follows:
– Switch off ignition and disconnect a wire of "weight" from the storage battery;
– Merge from system of cooling of a cooling liquid of 4 l;

Fig. 7.11. An arrangement of the gauge of temperature of a cooling liquid (ECT) on models till 2001


– Disconnect from gauge ECT an electric socket and turn out the gauge (fig. 7.11);
Address with the gauge very cautiously as its damage will lead to failure of system of injection of fuel.
Installation spend to sequences, return to removal. Before installation wrap up a carving of the gauge the teflon tape excluding formation of corrosion and preventing leaks.
