Key Signs of a Radiator Leak:

Coolant Puddles: If you see a greenish o r orange liquid under the front of your vehicle after it’s been parked, it’s likely coolant leaking from the radiator o r hoses.
Overheating Engine: A radiator leak leads to a loss of coolant, causing the engine to overheat.
Steam from the Hood: If the engine temperature rises too high, coolant may start to boil, producing steam visible from under the hood.

Diagnosis:

Visual Inspection: Look for visible cracks o r corrosion on the radiator and hoses.
Pressure Test: A radiator pressure test can help locate leaks by pressurizing the system to see where coolant escapes.
