Radiator Care 101: Everything You Need to Know About Coolant and Flushes

Introduction to Radiators and Cooling Systems

Your car’s radiator and cooling system are essential to keeping your engine running smoothly and efficiently. Overheating or poor temperature regulation can cause significant damage to your engine, resulting in costly repairs. At Auto Stop in Salisbury, we specialise in maintaining, repairing, and servicing your cooling system to ensure your vehicle performs at its best. By understanding how these systems work and taking steps to keep them in top condition, you can prolong your vehicle’s life and avoid unnecessary breakdowns

What an Engine Cooling System Does

The engine cooling system plays a vital role in regulating your engine’s temperature, ensuring it operates within an optimal range. Combustion engines generate a lot of heat, and without proper cooling, components can overheat, warp, or even seize, causing severe damage.

Your cooling system circulates coolant through the engine and radiator to absorb heat and disperse it, maintaining a steady operating temperature. In colder climates, it also helps prevent the engine from freezing. Extreme temperatures – whether high or low – can strain the cooling system. Overheating can lead to blown gaskets or cracked cylinders, while freezing temperatures can cause coolant to thicken or freeze, preventing proper circulation.

Hybrid and electric vehicles also rely on advanced cooling systems to regulate the temperature of key components, such as the battery pack, electric motor, and power electronics. Without effective cooling, these critical parts could overheat, leading to reduced performance or even permanent damage. Ensuring the cooling system is in good condition is vital for the efficiency and longevity of these vehicles.

Regular maintenance of your cooling system is essential to avoid these issues and to keep your engine performing reliably all year round.

Radiator Coolant and Its Importance

Radiator coolant, often referred to as antifreeze, is a liquid that prevents your engine from overheating or freezing. It also has anti-corrosion properties to protect internal components from rust and damage.

There are different types of coolants available, generally classified by their chemical composition. These include Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT) coolants. Using the right type of coolant is critical, as the wrong one can lead to corrosion in alloy radiators or deterioration in plastic components and seals.

To avoid costly damage, always consult your owner’s manual or speak to the service team at Auto Stop in Salisbury for guidance on the correct coolant for your vehicle. Using a high-quality coolant will protect your engine and radiator, helping them last longer.

Benefits of Coolant Flushing

Coolant flushing is an essential part of maintaining your vehicle’s cooling system. Over time, coolant can break down and become contaminated with debris, rust, or other particles. This reduces its effectiveness and can cause blockages in your system.

Flushing the coolant involves draining the old liquid, cleaning the system, and refilling it with fresh coolant. This process removes harmful build-up, ensures optimal performance, and prevents overheating or corrosion.

As a general guideline, a coolant flush should be performed every two years or 40,000 to 60,000 kilometres, depending on your vehicle and the type of coolant used. Regular flushing extends the life of your cooling system and helps avoid expensive repairs down the line.

Symptoms of a Faulty Radiator and Cooling System

A failing radiator or cooling system can show several warning signs, and catching these early can save you significant time and money. Common symptoms include:

- Engine overheating or temperature gauge consistently running high
- Coolant leaks under the vehicle
- Discoloured, sludgy, or low coolant levels
- Steam coming from the bonnet
- Poor heater performance during colder weather

To check your coolant level, ensure the engine is cool, and locate the coolant reservoir. The level should sit between the min and max markers. If it’s low, top it up with the recommended coolant type, but don’t ignore the underlying issue – get it inspected by our expert team at Auto Stop.

Radiator Checks During Every Service

At Auto Stop, we prioritise your vehicle’s health by performing a thorough check of the radiator and cooling system during every service. Regular logbook servicing is your best defence against unexpected breakdowns and costly repairs. Identifying potential issues early ensures that small problems don’t develop into major engine damage.
