Warning

An electric engine cooling fan under the hood can start up even when the engine is not running and can cause injury. Keep hands, clothing, and tools away from any underhood electric fan.

If the coolant inside the coolant surge tank is hot, do not do anything else until it cools down. The vehicle should be parked on a level surface.

The coolant level should be between the MIN and MAX lines.

If it is not, you may have a leak at the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system.

Warning

Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned.

Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.

there seems to be no leak, with the engine on, check to see if the engine cooling fan(s) is running.

If the engine is overheating, the fan should be running. If it is not, the vehicle needs service. Turn off the engine.

Caution

Running the engine without coolant may cause damage or a fire. Vehicle damage would not be covered by the vehicle warranty.

Caution

Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL (silicate-free) coolant in the vehicle.

Cooling system in 2014 Chevy Captiva is essential for maintaining the engine's optimal operating temperature, preventing overheating, and ensuring efficient performance. This system includes several key components: the radiator, water pump, thermostat, cooling fans, and coolant fluid. The radiator dissipates heat from the coolant, which circulates through the engine, absorbing heat and transferring it away to be cooled. The water pump ensures continuous circulation of the coolant, while the thermostat regulates the flow based on the engine's temperature. Cooling fans aid in maintaining airflow through the radiator, especially at low speeds or when the vehicle is stationary.

Regular maintenance of the cooling system is crucial to prevent overheating and potential engine damage. This includes checking coolant levels and quality, inspecting hoses and connections for leaks or wear, and ensuring the radiator and cooling fans are functioning properly. Over time, components such as the thermostat or water pump may fail, requiring replacement to maintain the system's efficiency. Flushing the coolant system periodically is also recommended to remove any debris or buildup that could impede coolant flow and reduce cooling efficiency.

Ensuring the cooling system operates effectively is vital for the overall health and performance of 2014 Chevy Captiva. A well-maintained cooling system not only protects the engine from overheating but also enhances fuel efficiency and reduces emissions. Regular inspections and timely repairs of the cooling system components can prevent costly breakdowns and extend the lifespan of the vehicle. Proper cooling system maintenance is a key aspect of vehicle care that contributes significantly to the reliability and longevity of the Chevrolet Captiva model year (from 2006 to 2018).
