Aston Martin Vanquish Water Cooler Radiator CD338W000BB

part number CD33-8W000-BB identifies the Engine Cooling Pack (Radiator and Oil Cooler Assembly) for the second-generation Aston Martin Vanquish (2012–2018).

Unlike many standard cars where the radiator and oil coolers are separate independent units, this Vanquish component is an integrated “cooling pack.”

1. Technical Breakdown

• Application: Specifically engineered for the AM11 and AM29 V12 engines found in the 2012+ Vanquish (and late-model DB9s).

• Construction: An aluminum high-efficiency core. The “BB” suffix indicates the latest engineering revision, often addressing previous issues with seam durability or mounting tab strength.

• Integrated Design: This unit typically houses both the Engine Water Radiator and the Gearbox Oil Cooler. Because the Vanquish uses a rear-mounted transaxle, the lines for the transmission fluid run the length of the car to this front-mounted cooling pack.

2. Shared Compatibility

This part is part of the “Generation 4” VH platform cooling system.

• Direct Fit: Aston Martin Vanquish (2012–2018) and Aston Martin DB9 (2013–2016).

• Earlier Models: While it looks similar to the radiator in the DBS V12 or early DB9, those often use the 8D33 or 4G43 prefix parts. The CD33 version has specific bracketry and hose diameters optimized for the higher output (565+ hp) engines.

3. Common Signs of Failure

• Seam Leaks: The most common failure point is where the aluminum core meets the plastic end tanks. Over time, heat cycles cause the crimped seal to weep pink/orange coolant.

• Oil/Water Mixing: Since the oil cooler is integrated, an internal failure can lead to “milkshake” fluid (coolant mixing with transmission oil), which can destroy the gearbox if not caught immediately.

• Debris Damage: Because of the Vanquish’s massive front grille, the radiator fins are susceptible to stone damage and “clogging” from road debris, which reduces cooling efficiency.

4. Pricing & Availability (2026)

This is a premium component and is significantly more expensive than radiators for the V8 models.

Maintenance Tip: The Foam Seals

When replacing this radiator, you must also replace the dedicated Foam Seal Kit (CD33-F8B171-AA). These seals ensure that air entering the grille actually passes through the radiator rather than escaping around the sides. Reusing old, compressed foam can lead to a 10–15% drop in cooling efficiency.
