What Causes the Water Temperature to Rise When Braking?
1 Answers
It might be an issue with the thermostat; try replacing it. The problem could also lie with the thermostat or the water pump—when braking, the pressure in the radiator might cause the thermostat to close or the water pump to stop working. This situation could also be due to a short circuit in the wiring. Therefore, it's recommended to visit a repair shop to inspect the wiring harness, especially focusing on the engine compartment wiring harness, to check if poor grounding is the cause. Here are some additional notes: Caution: Keeping the car in D gear while braking for a long time can cause the transmission fluid temperature to rise very quickly. Since the transmission fluid is cooled in the radiator (there is a partition between the coolant and the transmission fluid), heat conduction can lead to an increase in water temperature. It's advisable to use P gear when parking for extended periods.
