Common auto water pump fault condition, present these problems don't careless, hurry up to check

Auto launch machine in the process of running out will produce a lot of heat, but a machine can temperature through high, otherwise it will present oil cracking deformation, smooth, wear more, form a machine use the shortened lifespan. So it is very important to launch machine to stop cooling, there are a lot of cooling water circulation channel, the launch machine cylinder on the launch machine nozzle is equipped with water pump, fan belt drive, then the channels of heat pump, cooling water pump in, make a machine at a certain temperature range. Launch machine cooling water circulation normal have two loops: the pulmonary circulation and systemic circulation. When the car has just started, it is in the pulmonary circulation state, let a machine to heat up to 80 degrees (as soon as possible Different according to different models, the setting temperature. ) To the thermostat open working state, the car into the systemic circulation cooling system, through the water tank and the rapid cooling radiator coolant to launch machine to stop, to insist on a machine from overheating and go wrong. Water pump plays a key role, when the water pump to present problems, will affect the normal operation of the cooling system, ordinary water pump is broken there are the following conditions: 1, the idle speed problem is auto water pump and belt connecting to the cold water pumped from the tank to launch machine to stop cooling, if the pump rotation problem, will directly affect the launch machine speed, then is the problem of the speed, the phenomenon in the car for the general performance after start-up speed attacks beat is not stable, if resistance is very big and also can form a machine stalled. 2, water pump leakage water pump leakage is compare with common problems, mainly due to seal in place, it launched machine near the water pump leaking. Leakage coolant cooling fluid in the pump shaft color marks, incurred after the shortage of coolant temperature higher disease present, while the cooling fluid leakage on the water pump bearings, the bearing on the smooth agent to stop erosion, cause damage of bearing wear. 3 if the usual view to auto water pump, noise phenomenon presents obvious phenomenon of noise, so at this time is likely to pump once beginning damaged, and form the cause of the noise is inside the bearing damage or loose impeller presents, away from the axis of formation of the phenomenon of noise.
