Car radiators play an essential role in keeping the engine at the optimum temperature for the best performance. As such, any issues with the efficiency of your car radiator can also have an adverse impact on your vehicle’s engine. So how can car radiator efficiency be improved? And what can you do to keep your car running at its best?
So how can car radiator efficiency be improved?
There are a number of ways that car radiator efficiency can be improved, including:
- Keeping the radiator clean- It might sound basic, but keeping both the inside and outside of your radiator clean can make a big difference to its efficiency. This is because, over time, leaves, dirt, and road debris can build up on the front of the radiator, and this causes a blockage for the airflow. This makes it harder for heat to escape. As a result, giving the front grill and fins a regular clean with water or compressed air can make a big difference to the efficiency and performance of your car radiator, and the engine. Internally, you should consider flushing the radiator and replacing the coolant in line with the owner’s manual. This can remove sludge and internal blockages, helping to keep everything flowing smoothly.
- Using the right mix of coolant- It’s important to use the right mix of water and antifreeze. Too much water and it might freeze or cause corrosion; too much antifreeze and the liquid might not cool as effectively. The usual 50/50 mix is a good balance, but always check your vehicle’s manual. Modern coolant also includes additives that help prevent rust and improve thermal performance. As such, you should consider using high-quality coolant that’s suitable for your specific car, as this can make a noticeable difference.
- Upgrading your radiator- If you’re driving an older car, the stock radiator might not be up to the job. An aluminium radiator, for example, often performs better than older copper-brass ones. This is because aluminium conducts heat more efficiently and is usually lighter, which is a nice bonus for fuel economy too. There are also high-performance radiators available with extra cooling rows or larger surface areas. These are ideal if you regularly tow, drive in hilly areas, or have added engine mods.
- Checking the thermostat and radiator cap- These might seem like small parts, but they play key roles in the efficiency of your car radiator. The thermostat regulates coolant flow, so if it’s stuck closed, your engine will overheat. If it’s stuck open, your engine might not warm up properly, which also affects efficiency. Replacing an old or faulty thermostat can help keep everything running at the right temperature. The radiator cap keeps the system under pressure, raising the boiling point of the coolant and improving efficiency. A worn cap might leak or lose pressure, so it’s worth replacing it if you’re seeing signs of overheating or coolant loss.
