Check of serviceability of functioning and replacement of the block of the gauge of a measuring instrument of temperature of a cooling liquid

Start procedure performance only after full cooling of the engine! Preventions in the beginning see also Has undressed Antifreeze – the general data. Remember that at the included ignition the fan of system of cooling can work even at the muffled engine.



1. At refusal of a measuring instrument of temperature of a cooling liquid first of all check up a condition of corresponding safety locks (the Onboard electric equipment see).
2. If the measuring instrument fixes an engine overheat, address to the Section devoted to diagnostics of malfunctions of knots and systems of the car in Introduction to the present Management.
3. If at unequivocally cold engine the measuring instrument fixes an overheat, disconnect electroconducting from the measuring instrument gauge. If after a detachment of electroconducting of the indication of a measuring instrument fall, replace the gauge, otherwise it is necessary to check up electroconducting on a chain site between the gauge and a measuring instrument on presence of signs of short circuit on weight.
4. If the measuring instrument at serviceable safety locks does not function at all (the arrow remains motionless even after 10-minute warming up of the engine), muffle the engine and disconnect electroconducting from the temperature gauge. By means of a wire-crosspiece close a gauge wire on weight. For short time include ignition, without starting the engine, – if the arrow of the indicator deviates till the end of a scale, replace the gauge.

Do not leave the gauge connected longer, than it is really necessary for check!

5. If the gauge does not react in any way to connection, check up on breakage electroconducting. The probability of refusal actually a measuring instrument is not excluded also.



1. Uncover cases of a throttle and a flange of an inlet air line the throttle case. Then remove a flange of the case of a throttle from the inlet pipeline.
2. Disconnect from the gauge electroconducting.
3. By means of a high face head turn out the old gauge from the block (prepare for gathering of a spilt liquid).
4. Screw with demanded effort to the place of the removed gauge new which carving preliminary grease with current-carrying hermetic (not a teflon tape or tape ФУМ). Connect electroconducting.
5. Fill system of cooling and make sure of serviceability of functioning of a measuring instrument of temperature.
