Cold Weather Care: Radiator Repair, Coolant Flushes, & Hose Services

Cold weather can create all sorts of trouble for your vehicle. You might find your low tire pressure light on as the air begins to compress. Perhaps your battery light comes on as the cold makes it challenging for your vehicle to start. However, one less noticeable effect of the cold weather is radiator damage. Our local mechanics are here with everything you need to know about cold weather and vehicle radiator care. 


Why is the Cold Weather Bad For Radiators?


You might be wondering, “Why does the cold weather put my radiator at risk?” When the temperatures begin to drop, the coolant inside your radiator can begin to partially freeze. While antifreeze will not freeze until it reaches -36℉, coolant is actually a mixture of antifreeze and water. Unlike antifreeze, water freezes at 32℉. As such, your radiator fluid can begin partially freezing during the cold winter nights. 


Radiator Troubles and Cold Weather


So what happens when your radiator fluid begins to freeze? This process can cause a few adverse side effects, including:

  • The metal components of your radiator can begin to contract
  • Your radiator fluid can begin to expand
  • Radiator fluid can leak through damaged components 
  • Your radiator hoses and hose clamps can become loose or damaged

In these cases, your vehicle will require professional radiator diagnostics and repair services. This may involve hose replacement, radiator replacements, hose tightening services, or coolant services, among others. 


Preventing Radiator Damage in the Cold Weather


Thankfully, there are some steps you can take to keep your radiator protected. How do you prevent cold weather radiator troubles? Here are three main tips from our mechanics:

  • Park in the Garage: The easiest way to stop the cold weather from impacting your radiator is to park in the garage. This will protect your car from frost and ease the impacts of the harshest temperatures. 
  • Vehicle Covers: If you cannot park in your garage, you might consider investing in a vehicle cover. These will help trap in the heat of your vehicle and insulate your engine from the cold. 
  • Radiator Fluid Flush: Your radiator will be especially prone to cold weather impacts if it hasn’t received proper care. Sludge and debris in your radiator can impact the coolant freezing point and make your radiator more susceptible to cold weather problems. As such, it is essential you maintain your manufacturer-recommended radiator fluid flush routine. 
  • Routine Vehicle Maintenance: During routine service visits—such as your oil changes—your mechanic should take a look under the hood to visually inspect your belts and hoses. This will allow you to catch certain radiator issues early and minimize damage.
