Lexus Radiators 101

The radiator in your Lexus car or SUV is responsible for keeping your engine cool, preventing it from overheating and causing permanent, costly damage.

How Lexus Radiators Work

Radiators direct fluid (usually a mix of water and coolant) through inlet hoses to the hottest parts of the engine. The fluid collects the heat and then returns to the radiator via outlet hoses The radiator's large, flat, finned surface allows the heat to dissipate harmlessly into the atmosphere, leaving the radiator fluid free to make another trip through the engine.

How to Spot Radiator Issues

Even the highest quality radiator can eventually go bad, though. Signs of trouble include:

  • A damaged radiator fin
  • You hear odd engine noises
  • You detect sweet, syrupy smell of coolant in the air
  • Your coolant looks sludgy
  • You have HVAC problems
  • An overheating engine
