What to Do When the Car Temperature Is Too High?

[KiraLynn]

Here are the solutions for dealing with excessively high car temperature: 1. Check if there is excessive dust between the condenser and the radiator. Use high-pressure air to thoroughly clean them to ensure good heat dissipation performance of the radiator and condenser. 2. When the car is hot, check the temperature difference between the upper and lower radiator hoses. If the difference is too large, inspect the thermostat’s opening and whether the water pump has a speed loss issue. 3. After the car is hot, check the coolant reservoir’s upper return hose for proper water flow. Poor or blocked return flow can cause high water temperature, a common issue in Jetta models. 4. High pressure in the air conditioning system’s high-pressure end; excessive refrigerant or lubricant in the AC system, or malfunction of the self-adjusting function in the AC compressor, leading to excessively high pressure.
