Your engine produces a lot of heat, and the cooling system carries it away. When a hose splits, a water pump leaks or a fan stops working, temperatures can rise in minutes, especially in summer traffic. Overheating can warp a cylinder head and blow a head gasket, turning a modest repair into a major one.
We pressure test the cooling system to find leaks, check the thermostat, pump and fans, and use the correct coolant for your vehicle. Used antifreeze is collected for recycling.

If your car overheats
Pull over safely and switch off. Do not open a hot radiator cap. Let the engine cool, then call us on 011 783 3440. Driving on with an overheating engine risks serious engine damage.
Common questions
Can I just top up with water?
In an emergency, yes, but coolant protects against corrosion and overheating. Have it corrected soon.
How often should coolant be replaced?
Follow your manufacturer's interval. We check its condition at every service.
Why is my car losing coolant?
A leak, a faulty cap or, in worse cases, a head gasket. A pressure test finds it.
Does the aircon affect the cooling system?
They share the front of the car and the fan. See air conditioning.
