Why is the Audi's Water Temperature High?
1 Answers
Common causes of high water temperature include a broken fan belt, leaks in the radiator or water hoses, thermostat failure, or oil leakage. If the car loses engine power while driving or produces severe knocking or pinging sounds, it is often due to engine overheating. Here is relevant information: 1. Solution: Pull over to the side of the road but do not turn off the engine immediately, as excessively high water temperature can cause overheating of the pistons, cylinder walls, cylinders, crankshaft, etc., thinning the oil and reducing its lubrication effectiveness. 2. Specific reasons: During idle warm-up, due to the low engine speed, the oil pump cannot quickly pressurize lubricating oil into all lubrication surfaces, resulting in low oil pressure. This causes engine components to operate under dry or semi-dry friction conditions. Additionally, fuel may not atomize properly at low temperatures, allowing unburned oil to enter the crankcase and wash away the oil film on the cylinder walls, accelerating component wear. Therefore, after starting the engine, allow it to warm up at idle for several seconds.
