Your vehicle’s cooling system is vital to prevent engine overheating, which can cause severe damage and costly repairs. At Gauteng AutoClinic, we provide professional cooling system repairs and maintenance across Gauteng, ensuring your engine stays at optimal temperature regardless of driving conditions. Whether you drive a petrol or diesel vehicle, we service all makes and models with expert care and quality parts.
Engines generate immense heat during operation. The cooling system regulates this heat by circulating coolant through the engine and radiator, preventing overheating and component failure. A failing cooling system can lead to blown head gaskets, warped cylinder heads, or complete engine seizure. Regular checks and prompt repairs protect your vehicle’s longevity and performance.

Proper maintenance prevents engine overheating, reduces wear, and avoids costly engine damage.
The temperature gauge will rise above normal, you may see steam or coolant leaks, and experience poor engine performance.
Leaks can come from cracked hoses, faulty radiator, water pump seals, or damaged gaskets.
Typically every 40,000 to 60,000 km or every 2-3 years, depending on the manufacturer’s recommendation.
The engine may overheat or not reach operating temperature, affecting fuel efficiency and emissions.
Signs include coolant leaks under the car, overheating, and a whining noise from the pump area.
Yes, a clogged or leaking radiator can’t dissipate heat effectively, causing engine temperature to rise.
This can be due to low coolant levels, a faulty thermostat, or heater core issues.
Use the coolant recommended by your vehicle manufacturer, usually specified in the owner’s manual.
It’s not recommended because mixing can reduce the effectiveness and cause damage to the cooling system.
It varies by issue but most common repairs like hose replacement or radiator flush take a few hours.
