19 COOLING - EXHAUST - FUEL TANK 19 - 9 NOTE: The GMV thermocouple may not be repaired ;I t is located on the radiator. The G.M.V. thermocouple is located on the lateral right side of the radiator, attached on this. - it controls the engine cooling G.M.V. starting ,by means of a relay, when the temperature of the cooling fluid reaches to 95° C ( stage I ) and its stopping, when the temperature is - it controls the uncoupling of the AC compressor if the cooling fluid temperature reaches until to 105° C ( stage II )and permits its coupling when the temperature is lowering under 100° C. The thermocouple operation is performed in two stages of temperature, as follow: - stage I ( between the posts B and A) - coupling at 95° C and uncoupling at 90° C. In order to check the correct operation of the thermocouple, there are necessary the followings: - a battery (1); Make an assembly according to the a.m. diagram. A of the thermocouple should light up and shall remain so, until the temperature is lowering under If the lamp does not light up at the coupling temperature or it remains lit also after the temperature lowering, under the uncoupling temperature, replace the thermocouple. Then connect the lamp at the posts B and C of thermocouple ; it should light up when the cooling fluid reaches 1 4 2 3 COOLING G.M.V. THERMOCOUPLE CHECKING ( for Pick-Up with C.A. ) |
