The cooling system uses coolant (a mixture of antifreeze and water) to remove heat produced by the engine. The cooling system needs to be flushed to remove debris that could lower its efficiency.
The engine’s cooling system should be flushed every second year or every 30,000 miles to prevent the radiator from getting clogged with debris. Manufacturers may specify particular types of coolant to be used in their engines; Nexar auto repair in Katy will use the correct coolant in your vehicle.

Signs that your car engine is overheating:

  • The temperature gauge on your dashboard starts to rise, especially in Houston, the weather is hot in summer
  • Steam comes billowing out from under your hood
  • You hear hissing or pinging sounds
  • You smell antifreeze boiling over when any of these car cooling problems occur, stop driving immediately and wait until your car cools down. Do not attempt to open the radiator or pressure cap.
