Car Radiator Repairs

One of the most common problems that drivers have to deal with is the need for car radiator repairs. Despite the fact that the radiator is the most widely known component of a cooling system, when a malfunction occurs, the car radiator is very rarely the source of the problem.

Here at Advanced Radiators, we have listed some of the most commonly occurring vehicle cooling system faults:

A Failed Thermostat

When a vehicle overheats, it is most commonly the result of a failed thermostat. Contrary to popular belief, the thermostat is not actually a component of the car radiator itself; instead it is a form of valve that dictates the coolant levels flowing in and out of the radiator. By doing this, the thermostat helps to maintain the optimum operating temperature of the engine. However, when the thermostat begins to malfunction, the car can overheat extremely quickly.

Leaky Radiator Hoses

If a car's cooling system begins to leak, it is most likely to be the radiator hoses as opposed to the car radiator itself. This is because a car's radiator hoses link the car radiator to the engine, which then permits the flow of coolant between the two. A common feature of radiator hoses is that they are more prone to failure over time, meaning that they should be periodically replaced, regardless of whether they are functioning properly or not.

Air in the Cooling System

If air becomes trapped in a car's cooling system it can seriously restrict its efficiency; this is because the flow of coolant into the cooling system can be hindered. Therefore, if it appears that your car is running hot, it may be worthwhile having the cooling system bled in order to have any potential air bubbles removed.

Car Radiator Leaks

Leaks in the actual car radiator unit are much harder to locate and repair than car radiator hose problems. The best course of action is to see if you can spot any traces of steam or bubbles emanating from the radiator; this will help to identify the exact location of a leak. It is perfectly possible to patch-up leaky car radiators, but it is a somewhat difficult task.

A Failed Water Pump

The function of any engine cooling system is to efficiently regulate temperature. This is achieved through the use of a pump, which facilitates the movement of coolant throughout the engine; water first travels through the car radiator, then past the pump and into the engine, where it is then forced back into the radiator. If the water pump fails, then the car will overheat as a result of water no longer circulating properly; this is an extremely common problem with many engine cooling systems.

Cooling System Obstructions

An engine cooling system is subject to numerous obstructions; these obstructions can manifest in the form of engine 'scale', which can block the cooling passages in the engine or car radiator, making efficient flow of coolant extremely difficult. Obstructions can also occur in the car radiator air flow, such as bent fins or body damage; this makes it difficult for heat to be transferred from the radiator into the air.

A Failed Car Radiator Fan

A common feature of many modern cars is that they use an electric fan to pull sufficient amounts of air through the radiator, in order to keep the car cool at lower speeds and when it is stationary. If you find that your car overheats in heavy traffic, but is fine on the motorway, it will most likely be a problem with the car radiator fan.


 

How a Car Radiator Works

The primary role of a car radiator is to dispel any excess heat that is generated by a car's engine as it burns fuel. A car radiator is only one component of a larger engine cooling system, and as engine coolant moves through the radiator, it goes through a few simple processes.

There are three basic functions of your radiator: intake, cooling, and outlet. A car radiator is pivotal to the proper functioning of a car's engine, which is why it is integral to follow proper maintenance guidelines in order to keep the cooling system in good working order.

Car Radiator Intake

Example of crossflow and downflow car radiators

The primary function of an engine's water pump is to facilitate the flow of coolant that runs into and out of the radiator in a specific direction. The thermostat controls the amount of coolant that moves through the radiator, and it opens and closes according to the temperature of the engine. After this point, the coolant enters the radiator through the upper hose; there are two basic types of radiators - downflow car radiators and crossflow car radiators.

On a downflow radiator, coolant enters an upper tank and moves downwards across the body of the radiator. Whereas, the coolant enters a side tank (usually on the driver's side of the car), and flows sideways toward the other side of the radiator on a crossflow radiator.

Many modern cars use the crossflow design as it aids with bonnet clearance,
which is primarily due to the shorter vertical dimension of a crossflow radiator.

Car Radiator Cooling

As soon as coolant enters the first tank, it runs into small passages that join the two tanks together. Fine metal fins made from copper or aluminium, are connected to these small passages, which give the car radiator its distinctive ribbed appearance. The primary reason for using copper or aluminium is that they are highly effective at the conducting and transference of heat. Excess heat is transferred into the metal fins as coolant moves through the smaller tubes; the air is then forced through the spaces in between these fins, as a result of either car motion or the car's cooling fan; this heat is then dispersed away from the engine in the form of hot air, which prevents heat from building up in your engine, and thus preventing any overheating.

Car Radiator Outlet

Coolant is collected in another tank on the other side of the radiator once the engine coolant has moved through the cooling passages; this tank stores the coolant until it is moved into the outlet hose. The primary function of a car radiator's outlet hose is to connect the radiator to the water pump, and to supply low-temperature coolant to the engine as required. The outlet hose can be subjected to suction force from the water pump, which means that it is common practice to re-enforce the outlet hose with a spring; this prevents the outlet hose from collapsing, and thus maintaining the flow of coolant.
