Cooling System Degradation and Radiator Core Corrosion
SeriousCooling SystemThe densely packaged engine bay of the twin-turbo Ghibli II creates immense underbonnet thermal loads. Aging aluminium-and-plastic radiators, brittle header tanks, and tired coolant hoses perish over time, leading to sudden coolant loss. The aluminium-alloy cylinder heads and block have zero tolerance for overheating, which quickly causes warped cylinder heads and blown head gaskets. Specialist recored all-aluminium radiators are strongly recommended.

- Inspect radiator lower tank and aluminium fins for flaking corrosion and weeping
- Check coolant expansion tank for hairline heat cracks and oil contamination
- Verify that twin electric cooling fans trigger promptly at operating temperature
