ACDelco Radiator

An ACDelco Radiator is a heat exchanger located typically in the front of the vehicle, where air can flow through the fins while the vehicle is moving. A modern radiator is made from aluminum and plastic, while older vehicles used copper and brass. These radiators are corrosion resistant with optimal heat transfer characteristics.


  • Lightweight; the radiators have a positive heat transfer to weight ratio.
  • Corrosion-resistant aluminum core makes ACDelco Radiators long lasting.


Radiators generally require little maintenance, and don’t need to be replaced often, but there are some problems to look out for when it comes to your radiator:

Vehicle overheating: This is often a sign there is a problem with your cooling system, but it could be caused by various parts of your vehicles cooling system. It may be because of low or empty coolant level, broken/malfunctioning cooling fans, leaks from broken hoses, or a broken/damaged radiator.

  • Rust Accumulation: Radiators are constantly exposed to moisture, meaning they can be prone to corrosion. If you check your coolant and it has a brownish tint, then you may have excessive corrosion. It is best to have it inspected and flushed to clean out the rust. There are ways to try and prevent corrosion, mainly by using high quality coolant. Also, flushing the radiator, typically once a year, will stop excessive rusting and keep your radiator working efficiently.
  • Radiator Leaks: Radiators can develop leaks caused by various reasons. Radiators can become damaged in an accident or by rocks and other small debris in the road that can come up and hit the radiator. It is important to inspect your radiator for damage often. Damaged radiators should be replaced to ensure that your vehicle doesn’t leak coolant and overheat the engine.


Q: Are there benefits to using an aluminum core radiator?
A: Yes. The aluminum core has a longer life. The aluminum makes ACDelco Radiators light weight and gives them high efficiency.

Q: My engine is overheating. Does this mean I have to replace my radiator?
A: No. Often there are other pieces of the cooling system that cause the engine to overheat. It is important to check for hose leaks or a broken fan. If you look at the radiator and there is a lot of corrosion or holes, there may be a problem with the radiator. It is important to get the whole cooling system checked when your engine overheats.
