Fast diagnosis and effective repair
Preventative maintenance that saves money
Reliable Cooling For Every Drive
Your vehicle’s cooling system plays a vital role in regulating temperature and preventing costly engine damage. Over time, components like the radiator, coolant, and thermostat wear down or clog, affecting efficiency. Our comprehensive cooling services keep your system performing as it should, no matter the season or driving conditions.
We inspect for leaks, replace worn parts and flush your coolant to remove debris or corrosion. Regular cooling maintenance improves performance, protects the head gasket and helps your engine last longer. Whether you’re commuting or towing heavy loads, we’ll ensure your car stays cool under pressure.
Radiator Replacement & Repairs
The radiator is at the heart of your vehicle’s cooling system, responsible for transferring heat away from the engine. When it becomes blocked, cracked or corroded, overheating can occur quickly. We inspect the entire unit for damage, leaks and rust before recommending repairs or replacement. Using quality radiators designed to suit your make and model, we ensure consistent cooling and reliable performance. Regular radiator maintenance also prevents coolant loss and reduces strain on other components like the thermostat and water pump. Keeping your radiator in top condition is essential for efficient cooling and optimal engine health.
Coolant Flushes
Coolant — or antifreeze — prevents your engine from overheating in summer and freezing in winter. Over time, contaminants build up in the system, reducing effectiveness and causing corrosion. A coolant flush removes old fluid and replaces it with fresh, manufacturer-approved coolant to restore performance. This service also helps prevent scale buildup inside your radiator and hoses, ensuring efficient heat transfer. Regular flushes extend the life of your cooling components and improve temperature regulation. If you notice rust-coloured coolant or frequent overheating, a professional flush can make all the difference.
Thermostat Replacement
The thermostat regulates the flow of coolant between your engine and radiator. If it sticks open, your engine may run too cool, while a closed thermostat can cause dangerous overheating. Replacing a faulty thermostat restores proper temperature control, improving fuel efficiency and preventing major engine damage. Our mechanics use high-quality thermostats designed for your specific vehicle to guarantee accuracy and reliability. A well-functioning thermostat helps your engine reach operating temperature quickly and stay there, ensuring smoother performance and longer component life. Don’t ignore early warning signs like fluctuating temperature gauges or erratic heater performance.
Leak Detection & Repairs
Coolant leaks are one of the most common — and dangerous — cooling system issues. Even a small leak can lead to overheating and engine failure if left unchecked. We use advanced pressure testing and dye detection methods to pinpoint leaks in hoses, radiators, gaskets or water pumps. Once found, we repair or replace the affected parts using durable, high-quality materials to prevent recurrence. Early leak detection not only protects your engine but also saves you from costly repairs down the track. If you spot puddles under your car or smell sweet coolant, it’s time for a professional inspection.
FAQ
How do I know if my car’s cooling system needs repair?
Signs of cooling system trouble include rising temperature gauges, visible coolant leaks, steam from under the bonnet, or a sweet smell inside or outside the car. If your heater stops working or your engine overheats, the issue likely lies within the radiator, water pump or thermostat. Prompt inspection prevents severe engine damage.
How often should I change my coolant?
Most vehicles require a coolant flush every two to five years, depending on driving conditions and manufacturer recommendations. Neglecting coolant replacement can cause corrosion, clogging and reduced heat transfer. Regular flushes maintain efficiency, prevent rust and protect your engine from overheating or freezing.
What happens if my car overheats while driving?
If your car begins to overheat, pull over safely and turn off the engine immediately. Do not open the radiator cap until the engine cools completely. Continuing to drive risks head gasket failure or engine seizure. Arrange professional towing or inspection to locate and repair the cause before restarting.
