Frequently Asked Questions
The cooling system is a part of the engine that regulates the engine temperature and prevents engine breakdown due to overheating. The cooling system removes excess heat to keep the inside of the engine at an efficient temperature, approximately 94 °C (approximately 201 °F). All the parts that make up the cooling system have only one purpose: to ensure that the circulation of the coolant inside the engine can absorb and release heat.
Regardless of the climate, engines require a thermostat to bring it to the correct running temperature and to keep it there. Keeping the engine at the proper temperature prevents extensive engine damage. If an engine runs cold, it will produce sludge and corrosive acids that will prevent it from meeting legal emission control requirements.
The coolant is a mixture of antifreeze and water. The antifreeze lowers the freezing point and raises the boiling point. Coolant also protects the system from rust and corrosion.
When an engine is cold, the thermostat is cold. Coolant flows through the bypass hose and the water jackets to allow the engine to warm up evenly.
