Radiator Cap Failure – Overheat Prevention and Dispatch for Cross-Border Trips MyMechanic

Radiator Cap Failure on the Road – Why It Matters

• The radiator cap regulates system pressure and boil point; failure dumps pressure, causes coolant loss, and can overheat the engine.
• On long expressway trips, cooling systems are stressed; rapid temp rise or steam under the bonnet may trace back to a weak cap.
• Protect the engine: reduce heat load, pull over safely, and wait for cooldown before any checks.
