Can a bad thermostat cause a radiator leak?
The potential causes of a car radiator leak could be counted on one hand. The leading and most common cause is corrosion in the radiator. For instance, over-filling the radiator can cause leaks from increased water pressure. A bad thermostat or a heater core can also create excessive heat and pressure on the radiator.
How do I know if my radiator is leaking?
- Drop in Coolant Level. Coolant levels gradually drop as the vehicle operates, however, a drastic drop is a telltale sign of leakage.
- Puddle Underneath the Engine. When your car is parked, look out for fluid under the engine.
- Discoloration or Corrosion.
- Faulty Radiator Hoses.
