saab 9/7x water temp gauge and ac not working

• 2023-09-12

The saab 9/7x engine water temperature pointer deviates to the red area; The Computer fan is in the maximum state; Insufficient coolant; When the car is driving, the power suddenly disappears, and there are loud knocking and knocking sounds, mostly caused by the engine overheating. The normal water temperature of the engine is between 85 and 95 degrees Celsius. When the water temperature is too high, the viscosity of the oil will become thinner, the lubrication performance will decrease, and components such as pistons and valves are prone to deformation during high-speed operation, resulting in engine weakness. In severe cases, it may also cause cylinder pulling and crankshaft bearing. 

Insufficient cooling water in the cooling system causes the saab 9/7x engine temperature to be too high, so it is necessary to stop and wait for the engine to cool down before adding coolant; If the water pump or fan belt is too loose or broken, causing the engine temperature to be too high, it is necessary to go to a repair shop to replace the relevant components; The radiator guard mesh or radiator core ventilation duct is blocked by debris, resulting in poor heat dissipation and excessive engine temperature. Need to replace the heat dissipation shield or clean up debris; Insufficient engine oil or substandard oil quality, resulting in excessively high engine temperature. Simply replace with high-quality oil. 

Because if you turn on the saab 9/7x AC air conditioning, the fan will start together. After the temperature inside the car drops, the fan may pause intermittently . However , if you turn on the AC air conditioning and the fan still doesn't turn , it's not normal . There must be a problem . Your car's front fan does not turn while driving, and the water temperature will indeed remain within the normal range . In this case , the bearings of the fan should be reinstalled and fixed . The water temperature does not meet the requirements , and most car fans use electronic temperature control technology. Only when the saab 9/7x water temperature meets the standard can the air conditioning system function normally . Solution: If the air fan does not turn because the water temperature does not meet the standard , it is normal as long as the car saab 9/7x is warmed up and the water temperature reaches the normal standard.
