Check of functioning and replacement of the block of the gauge of temperature of a cooler

Before starting procedure performance wait full cooling of the engine.

The system of measurement of temperature of a cooler consists of the measuring instrument of temperature entering into a combination of devices and the block of the gauge of temperature, established on the engine. Some models are equipped more than one gauge, however for temperature indication uses only one of them, usually equipped with a single-wire electric socket. Gauges of temperature of the cooler, transmitting signals on the processor are usually equipped by two wires.

Site of the gauge of temperature of a cooler on the 6-cylinder engine.

Site of the gauge of temperature of a cooler on engine V8 (the second gauge located more to the right hands over the information on the processor).

In a case if the measuring instrument fixes an overheat, check up cooler level, then make sure of reliability of fastening of contacts of electroconducting between a measuring instrument and the switch. Check up a condition of safety locks.

At the included ignition and a turned starter the control lamp should burn (check of serviceability of a lamp).

If the lamp does not burn, or it has fused, or contour breakage takes place. Check up a contour, having earthed a wire between a lamp and the gauge at the included ignition (but without starting for safety the engine). If the arrow of a measuring instrument deviates thus on all range of a scale, or the control lamp lights up, replace the gauge.

Right after engine start the control lamp should go out and remain switched off before occurrence of an overheat of the engine. Refusal of deenergizing of a lamp can occur owing to закорачивания on weight of a wire between a lamp and the gauge, malfunctions of the gauge or failure of the lock of ignition. Make sure that the system is filled by a cooler of demanded type. The excessive quantity of water in a mix can be at the bottom of decrease in a boiling point of a cooler to value of the gauge insufficient for activation.

If the gauge block is subject to replacement, simply unscrew it from the engine and screw on its place the new. A carving part of the new gauge grease with hermetic. Before starting removal of the defective gauge make sure that the engine has completely cooled down. At вывинчивании the gauge inevitably there will be insignificant losses of a cooler - be ready to gathering of a spilt liquid. After installation of the new block of the gauge check up cooler level.
