Frequently Asked Questions

What are the main engine cooling components?

Car cooling system parts include the radiator, water pump, thermostat, and cooling fans. These parts work in concert to prevent overheating and maintain ideal system temperatures.

Is there a problem with my car’s cooling system?

Check out the temperature gauge when your car’s running. Is it high? That’s usually the most obvious sign of a problem. Other signs could include grinding noises, coolant puddles, or steam rising from the engine bay.

Why should you buy automotive cooling components from Sixity Auto?
