The Overlooked Part That Can Cause Your Engine to Overheat

It’s one of the simplest and most affordable parts in your engine bay, yet a failing radiator cap can cause catastrophic overheating. This small but essential cap is responsible for maintaining the correct pressure in your cooling system, which boosts the boiling point of your coolant. As our video explains, when the cap fails, your engine’s first line of defense against heat is compromised.

A radiator cap with a weak spring can’t hold pressure, causing coolant to boil at a lower temperature and leading to overheating in traffic or hot weather. At Epoch Automotive, we know that small details matter. We inspect the radiator cap during cooling system services to ensure it’s functioning correctly, preventing a simple failure from turning into a major one.

If you’ve noticed coolant leaks or your temperature gauge creeping up, a faulty radiator cap could be the culprit. Replacing it is a quick and affordable preventative measure against costly damage. Don’t risk an expensive radiator replacement when the solution is this simple. Call us at (267) 406-4922 to have our expert technicians inspect your cooling system today.
