OEM Acura Radiators

Refine Results

For your Acura engine to run properly, it needs to stay as cool as possible and avoid overheating. An original Acura radiator helps it regulate its temperature best. Thankfully, radiators work straightforwardly.

How Your Radiator Works

Engine coolant must first absorb heat. It does that by flowing between an inlet and outlet, back and forth via a radiator hose. As the coolant travels, your radiator cap compresses it. This helps the coolant take on as much heat as possible. The core block's brazed fins then release that heat, and a fan disperses it into the air nearby. The result: your engine runs cooler. That helps it work better and last longer. A radiator that's going bad, however, can start to cause problems.

Learn the Signs of a Failing Radiator

These include:

  • Engine overheating repeatedly
  • Odd noises coming from the engine
  • You detect the sweet, syrupy odor of coolant
  • Large pools of green, red, or yellow fluid underneath your vehicle
  • The HVAC system begins to act up
  • The dash warning light comes on
