A car radiator leak is bad news insofar as the radiator plays an essential role in ensuring that an engine doesn’t overheat.
Telltale signs of a car radiator leak are a sharp decrease in the level of engine coolant, an overheating engine or signs of coolant leaking onto the ground.
In an emergency should you feel that you are experiencing a significant car radiator leak, you should wait for the engine to cool down, add some water and drive the car to your nearest workshop.
Cooling systems and radiators take quite a bashing given the heat generated by modern engines.
By far and away the leading cause of coolant leaks is corrosion. The radiator, its hoses and connectors all collect sediment and rust which can perforate the radiator.
Over-filling the radiator can also cause problems through increasing the water pressure inside the radiator to the point at which it causes damage. A malfunctioning thermostat or heater core can also put too much pressure onto the radiator meaning that you will need to repair the coolant leak.
Our advice is to contact an authorised workshop should you experience problems with your coolant system. The workshop is likely to work to a process similar to the following:
Find the best coolant for your vehicle.
Running with a low oil level is incredibly bad for your engine, so it's important to check your engine oil regularly. Don't rely on dashboard warning lights alone; checking engine oil at the dipstick is a simple but important car maintenance task that absolutely everyone can do at home.
Most cars use a little engine oil over time so it is essential to maintain the right level of engine oil by topping up with the right oil whenever your dipstick check says your oil level is low.
Why choose full synthetic engine oil? Even if your warranty doesn't depend on you choosing synthetic engine oil, it's still the strongest and best choice for every engine. As long as you choose the right grade and specification of synthetic oil, it is guaranteed to exceed the manufacturer's requirements and give your engine the best possible protection.
While oil is a natural resource, it occurs deep in the ground where it can't damage plant and animal life. It's vitally important that any used engine oil from home car maintenance makes it to a recycling centre, as this ensures that it won't leak into the ground, potentially causing hazards to wildlife and water resources.
