CAR RADIATOR REPAIR

The radiator in your vehicle is designed to remove the heat generated by the engine to the air in order to regulate the engine temperature and prevent overheating. The engine block and cylinder head contain passageways filled with coolant (usually a mixture of water and glycols). The coolant is pumped around the car engine by the water pump and absorbs the heat generated in the engine by the combustion process. When it reaches the radiator the coolant flows through a series of tubes where it is transferred to the outside air via fins. The fins greatly increase the surface area of the radiator to make heat transfer more efficient.

WHY RADIATORS FAIL AND START LEAKING

Poor maintenance is the main reason why you can be left with a leaking car radiator, which can lead to the radiators failing. If the coolant has not been checked or topped up properly the inside of the cooling system will begin to rust and become clogged. Corrosion will eventually result in small holes developing. This will result in engine coolant loss, and a need for car radiator repair.

HOW MUCH DOES IT COST TO FLUSH A CAR RADIATOR?

The cost of flushing a car radiator will vary depending on whether you do it or employ a mechanic to do it.

If you do it yourself, you’ll be able to keep costs down and just pay for the new coolant, which should be around £20-£30.

If you go to a mechanic, the cost will be around £50-£60 depending on your car make and model.

K-SEAL TO THE RESCUE

K-Seal will permanently repair and fix most leaks in the radiator or radiator casing. Although the radiator may be one of the cheaper components in the car engine it can still cost hundreds to have it repaired or replaced. Just one bottle of K-Seal could quite easily save you a lot of money by fixing an engine coolant leak instead of replacing the parts.

Some rubber or epoxy seals and radiator hoses may also deteriorate over time but this type of leak may not be suitable for K-Seal. For larger holes such as those caused by stones hitting the radiator you should use QuikSteel Epoxy Putty – the world’s toughest putty used and recommended by professional motor mechanics.

How does a car radiator work?

The main function of a car’s radiator is to cool the internal combustion engine that powers the vehicle. Learn more about the function of a car radiator and its importance in running your vehicle.

What are the symptoms of a leaking radiator?

At some point, the radiator of most cars will develop a leak – it’s one of the most common issues that a car is likely to face during its lifetime. Discover how to spot the symptoms of a radiator that needs to be fixed.

How to flush your car’s radiator

Like any part of a car’s engine, regular (probably daily) use will mean that the radiator will begin to rust and build up deposits of coolant sludge inside it. Learn how to flush it to keep it running well.

Why Coolant Is Not Antifreeze

Although you might think that coolant and antifreeze are one and the same, you’re both right and wrong. Learn the difference between the two products.
