Frequently Asked Questions
What causes a car to overheat?
Overheating is usually caused by low coolant, leaks, a stuck thermostat, a faulty water pump or a blocked radiator. It can also happen if the radiator fan fails or the coolant mix isn’t right. Any of these can stop heat from being properly managed, leading to rising engine temperatures and potential damage if not addressed quickly.
How often should I flush my radiator?
Most manufacturers recommend flushing the radiator every 2 to 5 years or between 40,000 and 100,000 kilometres, depending on the coolant type and driving conditions. Over time, coolant breaks down and can’t protect against corrosion or overheating. Regular flushing keeps the system clean and working efficiently, especially if your car is older or under heavy use.
What are signs my cooling system needs attention?
Warning signs include temperature gauge spikes, visible coolant leaks, steam from the bonnet, a sweet smell while driving, or poor cabin heating. Discoloured or sludgy coolant is also a red flag. If you notice any of these, get your cooling system checked before it causes engine damage or a breakdown.
Pressure Testing
Cool Under Pressure
Your cooling system is the only thing standing between your engine and a meltdown. It requires more than just a top-up. We inspect pressure seals, radiator flow, thermostat function and coolant quality to protect your engine from heat stress and performance loss.
Whether it’s a routine flush or a full system overhaul, we keep cooling systems in check across all makes and models, including high-performance builds that tend to run hot. If you want reliability, longevity, and power, we’ll ensure your system stays steady. Find out more today.
