RADIATOR CAP: THE SMALL PART THAT MAKES A BIG DIFFERENCE! Your vehicle’s radiator cap might be tiny, but it plays a huge role in keeping your engine cool and running smoothly! More than just a simple cover, the radiator cap acts as a pressure regulator, ensuring that coolant circulates properly and prevents overheating. Why is the Radiator Cap So Important? ✅ Seals the Cooling System – Prevents air from entering, which can reduce cooling efficiency. ✅ Regulates Pressure – Maintains the right PSI to keep the coolant flowing properly. ✅ Prevents Overheating – Helps your engine stay at an optimal temperature, protecting against damage. Signs of a Failing Radiator Cap: ❌ Coolant leaks or overflow ❌ Overheating engine ❌ Low coolant levels without visible leaks Pro Tip: A faulty radiator cap is a cheap fix but can cause expensive engine damage if ignored! Regularly check your cap for wear and replace it if needed.
