Reach Radiators offer one of the largest product ranges in the aftermarket, covering more than 95% of the popular automotive and light truck applications. Reach Radiators meet or exceed original equipment specifications, ensuring that products fit and perform just as well or better than the original parts, providing you peace of mind.

Features and Benefits:

  • Deep extrusion headers provide a stronger tube-to-header joint that is more resistant to the effects of vibration and thermal tube expansion.
  • Folded fin edges increase stability and heat disbursement properties.
  • Radiators are the foundation of any engine cooling system. Tasked with preventing the vehicle from overheating, the radiator is vital to keeping vehicles up and running.
  • Reach B-Type tubes feature central reinforcement to provide greater tolerance to pressure reducing the probability of tube failure.
  • Reach utilizes longer header tabs for increased pressure resistance, this reduces the potential for tank-to-header leaks.
  • Thermal expansion reduce failure rates by allowing improved core expansion and contraction.
