FERRARI 599 GTB F141 Radiator Package

In 2026, the Radiator Package for the Ferrari 599 GTB Fiorano (F141) is a complex cooling suite designed to manage the massive thermal output of the 6.0L V12 engine. A full “package” or overhaul typically includes the main water radiators, the oil coolers, the AC condenser, and the fan assemblies.

1. Core Components & Part Numbers

By 2026, several of these parts have been updated (superseded) to improve durability, particularly regarding the aluminum welds on the main radiators.

2. 2026 Market Pricing (Estimated USD)

Given the age of the 599, many owners are moving toward high-performance aftermarket aluminum units (like those from Mishimoto or PWR) which are often more durable and cheaper than the Ferrari Genuine parts.

3. Common 2026 Issues & Failures

If you are replacing the cooling package, it is likely due to one of these three known 599 issues:

• The “Side Tank” Leak: The original 599 radiators used plastic end tanks crimped onto aluminum cores. Over 15–20 years, the heat cycles cause the plastic to fail. The 2026 standard is to replace them with fully welded aluminum units.

• Oil Cooler Corrosion: Because the oil cooler sits low in the front bumper, it is susceptible to rock chips and road salt, leading to slow “seep” leaks.

• Fan Controller Failure: The resistor packs on the fan assembly (222534) often fail, causing the car to overheat in traffic even if the radiators are new.

4. Installation Notes

• Bumper Removal: Accessing the full radiator package requires removing the front bumper and the internal air ducting.

• Bleeding the V12: The 599 V12 is notorious for “air locks.” In 2026, it is mandatory to use a vacuum filling system to ensure no air bubbles remain in the cylinder heads.

• Ducting Sealing: While the radiators are out, check the rubber/foam seals on the air ducts. If these are deteriorated, the car will run 10–15°C hotter because air will bypass the radiator cores.
