🚫 Do not drive — You should not drive with a bad radiator, as it can lead to severe engine overheating and permanent damage.
Key Takeaways
  • Verify your model year carefully; 2013 Impalas use a different radiator than 2014-2020 models.
  • Common failure points are cracks in the plastic side tanks, leading to coolant leaks and overheating.
  • A P0128 engine code can be related to a radiator leak, even though it often points to the thermostat.
  • High-quality aftermarket brands like Denso or Koyorad offer OEM-level performance for less money.
The radiator is the heart of your Impala's cooling system. Its job is to get rid of the heat the engine creates. Hot fluid, called coolant, flows from the engine into the radiator. As you drive, air moves through the radiator's thin fins, cooling the fluid before it goes back to the engine to pick up more heat. This process keeps your engine from overheating, which can cause very serious and expensive damage.

Understanding the 2013-2020 Impala Generations

It's important to know that the 2013-2020 range covers two different versions of the Impala. The 2013 model year was the last of the 9th generation, while the 2014-2020 models are the 10th generation. These cars are built differently and use different parts, including the radiator. Always confirm your vehicle's year before ordering to ensure you get the correct part.

Signs of a Failing Radiator

A bad radiator can't be ignored. If you notice any of these signs, it's time to inspect your cooling system.

  • Engine Overheating: This is the most obvious sign. If your temperature gauge is in the red, your radiator may not be cooling the engine properly.
  • Coolant Leaks: Finding puddles of green, yellow, or red liquid under the front of your car means you likely have a coolant leak. The plastic tanks on the sides of the radiator are a common failure point and can crack over time.
  • 🎬 Watch a video showing a common cracked radiator on this model.
  • Low Coolant Light: A frequent need to add coolant indicates a leak somewhere in the system.
  • Visible Damage or Corrosion: Look for rust on the radiator or damaged cooling fins. The connections for the transmission cooler lines can also corrode.
  • Steam from Engine Bay: If you see steam, pull over immediately. This is a sign of a significant leak or severe overheating.

Check Engine Light and P0128 Code

A common issue that can be related to a failing cooling system is the P0128 trouble code. This code means the engine's computer has detected that the engine is not reaching its proper operating temperature. While this is often caused by a stuck thermostat, it can also be triggered by low coolant levels from a radiator leak.

Choosing an Aftermarket Radiator Brand

When replacing your Impala's radiator, you don't have to buy the expensive dealer part. Aftermarket brands offer a range of quality and price. Here’s a breakdown of some available brands:

  • Premium Brands (Denso, Koyorad, CSF): These brands are well-regarded by mechanics. Denso is a trusted OEM supplier for many car makers. Koyorad is known for excellent quality and fitment that meets or exceeds factory standards. CSF is another strong choice. While they cost more than budget options, their reliability often makes them a worthwhile investment.
  • Standard/Economy Brands (Spectra, APDI, Global Parts, etc.): Brands like Spectra Premium are very common and generally offer a good balance of price and quality, though some users report shorter lifespans compared to premium brands. APDI is a budget-focused brand; some forum users have reported issues with quality and fitment. These brands can be a good choice if budget is your main concern, but be aware that quality can be inconsistent.

OEM vs. Aftermarket Quality

For the Impala, a high-quality aftermarket radiator from a brand like Denso or Koyorad can perform just as well as the original OEM part, often at a much lower cost. The key is choosing a reputable brand. Budget-tier brands can be a gamble, with some owners experiencing leaks or fitment problems sooner than expected.

Cost to Replace a 2013-2020 Impala Radiator

The cost depends on your vehicle's year, the parts you choose, and who does the work. The 2013 model and the 2014-2020 models have different parts and labor costs.

Frequently Asked Questions (FAQ)

Are there any recalls for the 2013-2020 Impala radiator?

No, there are no specific recalls for the radiator on the 2013-2020 Chevrolet Impala. However, a Technical Service Bulletin (TSB) was issued for 2012-2016 Impala police vehicles regarding premature wear on the cooling fan motor due to extended idling, which can affect cooling performance.

Can I replace the radiator myself?

Yes, for a DIYer with some experience, this is a manageable job. It typically involves draining the coolant, removing the airbox, disconnecting hoses and transmission cooler lines, and unbolting the fan assembly and radiator. It generally takes a few hours. If you are not comfortable working with your car's cooling and transmission systems, it's best to leave this job to a professional.

🎬 Follow this step-by-step DIY guide to replace your Impala radiator.
What is the most common reason for Impala radiators to fail?

The most common failure is a crack in the plastic side tanks, which leads to coolant leaks. This happens because the plastic becomes brittle over time from constant exposure to heat and pressure changes.

Do I need to replace my radiator cap too?

It is always a good idea to replace the radiator cap when you install a new radiator. A faulty cap can fail to hold pressure, lowering the boiling point of your coolant and leading to overheating, or it can cause hoses to collapse. It's an inexpensive part that is critical for the system to work correctly.

What coolant should I use for my 2013-2020 Impala?

Always use the coolant type specified in your owner's manual. For these Impala models, this is typically a DEX-COOL compatible coolant. Using the wrong type can lead to corrosion and damage to your cooling system.
