Why Your Car's Radiator Needs Regular Flushing
A radiator flush is essential for maintaining your engine's cooling system. Over time, coolant breaks down, collects dirt, and forms rust, leading to clogs and overheating. Regularly flushing the radiator removes old coolant and deposits, ensuring your engine runs at optimal temperatures.
Signs Your Radiator Needs Flushing
Your car may need a radiator flush if you notice these signs:
- Overheating engine
- Coolant color change (dark or rusty)
- Low coolant levels
- Steamy or sweet-smelling exhaust
- Rust or sludge in the coolant
