911 oil temp gauge marks

The normal operating temperature of the Porsche 911 oil is generally 70-90 ° C. If the speed is high, the temperature will be relatively high, reaching about 100-110 ℃. If the temperature exceeds 120 ℃ for a long time, check it. Excessive oil temperature is a comprehensive fault.

Causes of high oil temperature: coolant defect. The cooling radiator is blocked. Scale or dirt in the water tank increases the resistance to coolant flow. Loose fan belt causes insufficient cold air in the water tank. A loose water pump belt or a corroded water pump impeller will reduce coolant flow. The concentration of antifreeze coolant is too high. The thermostat fails, causing the temperature to rise, but it still cannot be opened. There is air in the cooling system. At this time, set the exhaust air gas switch to the exhaust air gas position.

The influence of oil temperature on vehicle driving: too low temperature is not conducive to combustion, thus affecting power; If the temperature is too high, it is a great test for all parts of the engine, especially the oil seal and cushion. Therefore, it is better to control the oil temperature between 90 ℃ and 100 ℃ when using the car at ordinary times, and it does not matter if the temperature is 100-110 ℃ occasionally. One day, the temperature reached 120 ℃ after driving hard, but after a while, the temperature will return to the normal driving state, which is no problem.Causes of high oil temperature: coolant defect.

Therefore, the oil temperature should be controlled between 90-100 and 100-110 occasionally.
