A complete guide to car radiators

Functions of a car radiator

Car radiators function to keep an engine cool and your vehicle running perfectly as a result, meaning they are among the most important pieces of equipment you will find under the bonnet.

It’s not just the engine that a car radiator works with though. They are also built into your vehicle to keep various lubricants and fluids at an adequate temperature — power steering fluid and transmission fluid included.

Types of car radiator

Car radiators come in two primary designs:

  1. Cross flow radiators, which use tanks found on either side of the radiator core so that the coolant can cycle back and forth across the core. This setup enables heat to be dissipated across a spacious area.
  2. Down flow radiators, which utilise a conventional vertical-flow design along with an expansion inlet tank at the top of the core so that coolant can circulate effectively through the radiator.

As well as these primary types of car radiators, it is important to note that copper and brass core car radiators have slowly been making way for those with aluminium cores which make use of plastic tanks. This is because:

  • Aluminium cores carry a lot less weight.
  • Aluminium cores are more cost-efficient.
  • Aluminium boasts an impressive rate of heat transfer when compared to many other common metals.

Car radiators and coolant

As seen when looking into the types of car radiator available, coolant is an important part of how the technology works.

Coolant is a combination of antifreeze and waterthat’s pumped around an engine to a radiator, with the antifreeze preventing any water found in the radiator from either freezing or boiling.

It is crucial that you do not allow your car radiator’s coolant level get too low, as this issue can result in your entire vehicle overheating. Fortunately, water is all you need in order for the coolant to stay at its recommended level.

Car radiator caps

As well as the car radiator itself, it’s important to cover the device’s cap too.

First and foremost, a car radiator cap should never be opened if the vehicle’s engine is hot. Doing so presents a high risk of a person being scalded.

Malfunctioning car radiator caps are another problem to be aware of. This is because coolant could leak if a radiator cap has not been screwed on properly, while the car radiator’s water pressure could be compromised if the cap isn’t sitting correctly.
