Common Causes Of A Failing Car Radiator That You MUST Be Aware Of

By Zunsport - 3rd May, 2024

A car radiator is an essential component of a vehicle. However, like any other part, it can go wrong. Here are common causes of car radiator problems and solutions you need to be aware of.

What Is A Car Radiator?

Essentially, a car radiator helps to keep the engine cool. This vital heat exchanger works to reduce the temperature of the coolant or antifreeze in the engine, thanks to narrow tubes that help to disperse heat quickly.

Because radiators help to keep the engine's temperature in check, when problems do occur, one of the first signs of car radiator problems will be overheating. This could manifest as steam coming from under the engine and a sharp rise in the temperature of the engine.

Fortunately, with regular care and maintenance, car radiator problems shouldn't become a frequent occurrence. But, when car radiator cap problems and other radiator issues happen, the following reasons may be to blame.

Faulty Radiator Fan

A fan helps to keep the radiator cool. However, it only kicks into action at low speeds, so if you notice your car overheating at lower speeds but returning to normal at higher speeds, a faulty fan might be the culprit. Another reason for a rapidly rising temperature reading could be a faulty thermostat. Never ignore signs of an overheating vehicle.

Hose Leaks

Over time, wear and tear to the hoses that circulate coolant or anti-freeze to the radiator can occur. In fact, this is one of the most common problems affecting a radiator, and even driving over potholes frequently can result in cracks or splits forming in the hoses. Signs of car radiator problems caused by worn or damaged hoses include leaky fluid patches on the ground or on the engine and the warning light displayed on the vehicle dashboard indicating overheating.

The water pump that moves coolant or anti-freeze through the engine and radiator can also malfunction over time, reducing the necessary water flow rate.

Holes And Cracks

As well as holes and cracks forming in the hoses, these can occur within the radiator itself. Often the result of wear and tear, holes and cracks in the radiator may also be the result of sudden or sharp movements of the vehicle. Signs that holes and cracks in the radiator may be present are similar to those for a leaky hose.

Protect Your Vehicle

Good maintenance will help to protect your car radiator, but installing a Zunsport Grille to the vehicle can also assist to encourage effective ventilation that keeps the engine cool. Get in touch with Zunsport today.
