Frequently Asked Questions
What is car coolant service?
Car coolant service, also known as coolant flush and fill, is a routine maintenance procedure that involves draining the old coolant from your vehicle’s cooling system, cleaning the system, and refilling it with a new coolant mixture. The coolant helps to regulate the engine’s temperature by absorbing heat from the engine and transferring it to the radiator, where it is dissipated. Over time, the coolant can break down, lose its effectiveness, and even contaminate the cooling system, which can lead to engine damage. Regular car coolant service helps to prevent these issues and ensure your vehicle runs efficiently and safely.
How does car coolant service work?
The car coolant service process typically begins with a visual inspection of the cooling system to identify any signs of leaks or damage. The technician will then drain the old coolant from the system, using a pressure test to ensure the system is fully drained. The radiator, hoses, and other components are then cleaned and flushed to remove any debris or contamination. After cleaning, the system is refilled with a new coolant mixture, which is designed to meet the manufacturer’s specifications. Finally, the coolant level is checked and the system is tested to ensure it is functioning properly.
