Frequently Asked Questions

What is a Radiator and what does it do?

RadiatorA simple answer is "an automotive radiator keeps down engine temperatures in motor vehicles". The engine heats up during driving and the automotive radiator cools your vehicle using a combination of water and anti-freeze coolant that prevents overheating. The automotive radiator consists of several folds designed to increase surface area of the radiator allowing air to pass over and dissipate the heat made from your motor. The coolant becomes superheated as it touches the engine, flows through the hoses and cools back down as it travels back to the radiator.

Why do you need a radiator?

Engines create a lot of friction as the moving parts work to propel your car. This friction inevitably creates heat, which eventually reaches levels that can cause a motor to stop working. The automotive radiator keeps the engine and its components from reaching high levels, thus keeping the engine cool. Without a well maintained radiator, your engine will break down.

Who makes radiators?

Most car manufacturers have their own line of automotive radiator models. There are also many third-party manufacturers that offer automotive radiator units, but not all are equal. WA Mobile Radiators source directly from a well trusted and known radiator supplier.

How long do radiators last?

Many people will answer this question with an answer stating "how long is a piece of string". Providing a radiator is well maintained, flushed on a annual basis, quality coolant/anti freeze added and all other items in the cooling system working efficiently, then there is no reason why a radiator cant last past 10+ years. The simple answer to the question is "a radiator will last as long as it is properly maintained".

What to look out for…

Cooling System Leaks - Loss of coolant because of a leak is probably the most common cause of overheating. Possible leak points include hoses, the radiator, thermostat housing, water pump, head gasket, automatic transmission oil cooler, cylinder heads and the motor itself.

Fan - With mechanical fans, most overheating problems are caused by a faulty fan clutch. Another problem can be a missing or removed fan shroud. This can reduce the fan's cooling effectiveness by as much as 50 percent. With an electric cooling fan, check to see that the fan cycles on when the engine gets hot and when the air conditioner is on. If it fails to run, the fan motor is bad or the automotive wiring may be faulty, it needs to be checked and or replaced.

Water Pump - Any movement in the pump shaft or seepage would require a replacement water pump. In some instances, a pump can cause an engine to overheat if the impeller is badly eroded due to corrosion. The wrong pump may also cause an engine to overheat.

Radiator - The most common problems radiators fall prey to are clogging both internal leaks (from the corrosion of the block) and external leaks (bugs and dirt lodged in the fins of the radiator). This can block air flow through the core and reduce the radiator's ability to dissipate heat. Internal corrosion and an accumulation of deposits can likewise inhibit coolant circulation and reduce cooling.

Overworking the Engine - The cooling systems in many passenger cars today are marginal and have little excess capacity to handle extra heat generated by towing or high speed driving in hot weather.
