Maintaining your vehicle is essential if you want to keep it running well and operating at peak performance. The usual maintenance procedures, such as oil changes, are usually not issues for most people – but performing basic maintenance operations to keep your radiator and engine running well are just as important yet more often overlooked. Radiator maintenance is an integral part of the overall “health” of your vehicle because the engine has to remain at a prime operating temperature in order to work properly. If your engine overheats, for example, you’ll have a lot more headaches than if you keep up with important maintenance tasks on a regular basis.

Radiator maintenance is mostly about the fluids. Other problems with the cooling system can arise, for various different reasons, but for basic maintenance and upkeep properly maintaining the vital fluids in the radiator is what will keep your vehicle humming with life for years to come. Whether you utilize the services of your local shop to perform key maintenance and repair processes or do everything yourself, it is recommended that coolant is replaced every year or so. In addition to coolant replacement, it is also a good idea to flush and refill the radiator every 1 to 2 years to ensure the cooling system will run well, even if your mileage is low after this period of time. Following such a maintenance schedule is vital if you want your vehicle to be properly and consistently maintained.

Why Antifreeze is Key

Antifreeze/coolant is a big part of what keeps your engine in top working order. In addition to its cooling properties and ability to keep your engine running under extreme temperature variations, many companies also include other ingredients that help keep your engine working well. For instance, antifreeze can contain additives that prevent rust and corrosion of the radiator, engine and vehicle heater. If you neglect radiator maintenance the advantages of a good cooling system will not be fully utilized.

Basically, coolant is a 50/50 mix of glycol and water, depending on your vehicle. The glycol portion of the mixture is the antifreeze – it works to keep the water from turning to ice in cold temperatures and reaching the boiling point in extreme heat. With the coolant operating at the proper degree, the engine will continue running at a stable temperature in all climates and driving situations.

Ethylene glycol is used in antifreeze but it requires proper handling if you are planning on performing cooling system maintenance on your own – it is a toxic substance that can cause health problems or even death, and can be damaging to the environment. Following suggested protocol when handling antifreeze is a necessity. Keep it away from children and animals, and ensure proper disposal according to local hazardous waste regulations. A recent alternative to ethylene glycol is propylene glycol. Antifreeze that contains propylene glycol is less toxic than its predecessor, especially at low levels, but it still must be handled with caution. No matter what antifreeze you use, the fluid picks up heavy metals during usage, so disposal is something to be taken seriously. Follow the same procedure you would with any antifreeze product and you will avoid problems when performing maintenance on your vehicle at home. It is very important that you do not pour coolant down your sink or into storm drains due to its toxic properties.
