Is a 110°C Water Temperature Normal for the Envision?
2 Answers
The water temperature of 110°C in the Envision is not a normal phenomenon, but the car allows the temperature to exceed 100°C for a short period. Below is more information about the thermostat: 1. Introduction: The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. 2. Working Principle: The thermostat commonly used in cars is a wax-type thermostat. When the coolant temperature is below the specified value, the refined paraffin in the thermostat's temperature-sensing body remains in a solid state, and the thermostat valve closes the channel between the engine and the radiator under the action of a spring. The coolant returns to the engine via the water pump, performing a small circulation within the engine.
As a seasoned driver with decades of experience, I've seen all kinds of coolant temperature issues. The normal operating temperature for a Buick Envision should be maintained between 90 to 100 degrees Celsius. Occasionally reaching 105 degrees is still considered safe, but if it frequently jumps to 110 degrees, there's definitely a problem. Possible causes include insufficient or degraded coolant, malfunctioning water pump, or a thermostat stuck in the closed position causing poor heat dissipation. I once had a car with elevated coolant temperature myself - just adding some coolant brought it back to normal. If you ignore this issue, the engine may overheat and damage the cylinder head gasket, leading to expensive repairs. I strongly recommend checking your cooling system immediately, topping up fluids, and consulting a professional mechanic if necessary. Don't let a minor issue turn into a major disaster.
