Problem overview

Some INFINITI FX35 owners report experiencing issues with cracked and leaking radiators, which can render the vehicle undriveable. These radiator leaks are often caused by corrosion and rust from prolonged exposure to heat and pressure, as well as cracked radiators, faulty radiator hoses, or water pump problems. Signs of a radiator leak include coolant puddles under the vehicle, low coolant levels, overheating, rust, and a sweet smell. To diagnose the issue, owners may use visual checks, pressure testing, or the UV dye method. While some owners resort to temporary fixes such as radiator stop leak products, epoxy, and tightening clamps, it is crucial to seek professional assistance to address the radiator issue promptly. Driving with a cracked and leaking radiator can lead to severe overheating, engine damage, and other serious safety concerns, making it essential to prioritize resolution before attempting to drive the vehicle again.
