Cooling System

What is a cooling system?

The cooling system’s job is to keep the engine at an optimal temperature. A pump circulates the liquid coolant, which is the mix of antifreeze and water, through the engine to draw heat. The coolant is then cooled in the radiator. Parts such as the thermostat, pressure cap, and hoses complete the cooling system.

Why is my cooling system important?

When it comes to coolant, it is crucial to have the proper amount in your cooling system. If you don’t have enough coolant, it can’t keep your engine cool. You also need the right kind of coolant. Different makes of vehicles require different coolant formulations to protect against corrosion. Finally, your coolant needs to be fresh. Over time and kilometers, the anti-corrosion additives deplete resulting in damage.

The smallest leak can decrease the amount of liquid coolant to below a safe level, which may create harmful conditions for the engine. If the vehicle has a temperature gauge, the needle will hit the red zone to warn the driver. If the Check Engine light comes on, there’s already a risk of damage.

Depending on your vehicle, we have the right coolant or cooling system parts.

For a cooling system inspection well done.

Since the cooling system is subjected to high temperatures in extremely rigorous conditions, it should be inspected regularly.

In addition to the cooling system, the coolant should be replaced on a regular basis. Failing to change the coolant can cause the system to clog, which raises the internal engine temperature. Each automotive manufacturer provides recommendations regarding the correct coolant and how often to replace it. Your certified NAPA AUTOPRO technician will know this information.

While inspecting the cooling system, your certified NAPA AUTOPRO technician will clean the system, top up the correct liquid coolant, check each part of the cooling system, and make sure it’s all running smoothly.
