Signs Your Cooling System Needs Attention

Look out for the following indicators:

  • Engine overheating or frequent temperature spikes: If your gauge climbs steadily or unpredictably, it could indicate low coolant levels, thermostat issues, or a clogged radiator.
  • Visible coolant leaks or puddles: Bright green, yellow, or orange fluid under your vehicle or around the radiator cap is a clear sign of a leak.
  • Steam from under the hood: Steam or smoke suggests overheating; CBAC warns to stop driving immediately and have the system inspected.
  • Discolored or burnt coolant: Rusty, dirty, or dark coolant loses its efficiency and indicates internal corrosion or buildup.
  • Unusual engine noises or poor mileage: A failing water pump, corroded hoses, or inefficient coolant flow can cause noise and lower fuel efficiency.
