The radiator is the heart of a vehicle's cooling system. So, when it comes to replacing a worn radiator, you need a product that will match the original factory part in fit, form and function. ACDelco offers dependable, long lasting GM Original Equipment radiators for GM vehicles.

  • Superior fin waves provide a higher heat transfer
  • Lightweight; the radiators have a positive heat transfer to weight ratio
  • Corrosion-resistant aluminum core makes ACDelco GM OE Radiators long lasting
  • Manufactured to GM OE specification for fit, form, and function
Service Tip: If you are experiencing unexplained or reoccurring radiator core leaks, or notice dark spots on your failed radiator core, test your coolant for Electrolysis. If detected, correct the source of the problem before replacing your failed radiator to prevent repeat failure.

Cooling System Maintenance | Tips & Tools

Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:

  • Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
  • Consider replacing the Radiator Hoses (and Hose Clamps), Thermostat and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
  • Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
