Fleet safety tip: Preventing your vehicle from overheating

The dog days of summer have finally arrived, and the summer heat can greatly increase the chances of your vehicle overheating. The increase in external warmth puts your engine at a disadvantage when trying to maintain a sustainable temperature. If your vehicle is not properly prepared for the heat, then engine damage can occur.

Here are some ways to help prevent your vehicle from overheating:

  • Make sure your radiator has plenty of coolant (antifreeze) in it – Lack of coolant is the number one reason for engines to overheat
  • Coolant has a life span, so be sure to keep fresh coolant in the vehicle – Old coolant can cause corrosion and make other components weaker against high temperatures  
  • Make sure your radiator cap is not cracked and screwed on completely – The cap maintains the pressure within the radiator and prevents the coolant from boiling
  • Clean the radiator often - Dirt, leaves, bugs and other grime can clog the airflow in the cooling system
  • Check the status of your vehicle’s thermostat, belts, hoses, water pump, radiator and fans – These components are important because they all help maintain the temperature of the vehicle
  • If your vehicle shows signs of overheating: pull over, shut off the engine and call for road service - Shutting your engine down quickly can help avoid turning a minor repair into a major one 

Overheating damages are costly, inconvenient and a major headache. Using these tips will keep your vehicle cool this summer.
