Your vehicle’s radiator is a crucial component that needs to be taken care of. The radiator sends coolant and water throughout the engine to ensure it stays cool and doesn’t overheat. The weather has a huge impact on your radiator and how it behaves. Knowing exactly how the weather affects your radiator can help you maintain optimal performance for your vehicle throughout the year.


In this blog, the experts at Applied Radiators have shared our top tips on weather and radiator performance.


How Winter Can Impact Your Radiator

You’d think winter would be great for radiators, right? Well, not really. Winter can be particularly harsh on your radiator. Cold weather can cause coolant to thicken, making it harder for heat to be transferred away from the engine. Low temperatures can even freeze coolant, which can cause major damage to the radiator. It's essential to use antifreeze in your coolant mixture during winter to prevent freezing.


How Hot Weather Affects Your Radiator

In hot weather, your radiator has to work harder to dissipate the excess heat generated by the engine. High temperatures can cause the coolant to evaporate more quickly, potentially leading to low coolant levels. This can result in overheating, which may cause severe damage to the engine. Regularly checking and topping up your coolant levels during summer is crucial to prevent your engine from running hotter than the summer sun. 


Tips on How to Keep Your Radiator Running all Year Round

Regular maintenance is the key to keeping your radiator in top condition throughout the year. Check your coolant levels frequently and top up when necessary. Ensure your coolant mixture is appropriate for the season—antifreeze in winter and a higher water ratio in summer. Periodically inspect your radiator for any signs of leaks or damage. Have your radiator serviced by professionals to keep it in top condition.
