- The most common failure is a leak from the plastic side tanks where they are crimped to the aluminum core.
- Aftermarket brands like Denso, CSF, and Koyorad offer excellent quality for less than OEM prices.

Is Your Impala's Radiator Failing?
The most common failure on 2006-2012 Impala radiators is a leak from where the plastic side tanks are crimped to the aluminum center (core). This is often due to age and constant pressure changes. You might see signs of pink or orange Dex-Cool coolant residue on the side of the radiator or a puddle under your car. 🎬 Watch this video to identify common signs of radiator failure. Other signs include the engine temperature gauge running hotter than normal, a low coolant warning light, or steam coming from under the hood.
Known Issues for This Generation
While there are no direct recalls on the radiator itself for the civilian models, some issues in the cooling system can put extra stress on it. Some Police Package (9C1) Impalas had TSBs (Technical Service Bulletins) for issues with cooling fan relays that could cause overheating. Additionally, some 3.5L and 3.9L V6 engines had a TSB for a potential coolant leak from a crossover pipe gasket, which could lead to low coolant levels and overheating if not addressed. Always check your coolant level if you suspect a problem.
Choosing the Right Aftermarket Radiator
When replacing your Impala's radiator, you don't need to buy an expensive part from the dealer. Aftermarket brands offer good quality, often for much less money. They are designed to be direct-fit replacements, meaning no modifications are needed for installation. Here’s a breakdown of common brand tiers.
Premium Brands (Highest Quality & Reliability)

- Koyorad: Another top-tier brand that offers OE-equivalent quality and is known for its reliability and proper fitment.

Pro Tip: Replace More Than Just the Radiator
While you have the cooling system drained and accessible, it's a smart move to replace the upper and lower radiator hoses, the thermostat, and the radiator cap. These parts are relatively inexpensive and wear out over time. Replacing them all at once can prevent future leaks and save you from having to do the job twice.

Frequently Asked Questions
Is it hard to replace the radiator on a 2006-2012 Impala?
For a DIYer with some experience, it's a manageable job. It requires draining the coolant, disconnecting hoses and transmission cooler lines, removing the cooling fans, and then unbolting the radiator. The most difficult part can be accessing the lower transmission line clips and separating the AC condenser from the radiator. It typically takes 2-4 hours.
🎬 Follow this step-by-step guide to replace your Impala's radiator.Do I need special tools for the replacement?
You'll need basic hand tools like sockets and wrenches (10mm, 13mm, 15mm), pliers for hose clamps, and a drain pan. A special tool for disconnecting the quick-connect transmission lines can make the job much easier, but it's not always required.
What kind of coolant does the 2006-2012 Impala use?
This generation of Impala uses Dex-Cool coolant, which is typically orange or pink. It's important to use a Dex-Cool compatible coolant and not mix it with other types, like the traditional green antifreeze.
Do I need to bleed the cooling system after replacing the radiator?
Yes, it is critical. After refilling the system, you must bleed any trapped air out. Air pockets can cause overheating even with a new radiator. This involves running the engine with the heater on high and letting it reach operating temperature to allow the thermostat to open and circulate all the coolant.
