Radiator Cap Video
While the radiator cap may seem like a small part, it plays an important role in your vehicle’s cooling system. It helps maintain proper pressure within the system, which allows coolant to circulate effectively and helps regulate engine temperature.
The radiator cap is designed to hold coolant under a specific amount of pressure. When that pressure reaches a certain level, the cap can release excess pressure to help protect the system.
If your car, truck, or SUV is overheating, it’s important not to open the radiator cap while the engine is hot. Pressurized coolant can escape and cause burns.
If you’re experiencing cooling system issues, the team at Blackwell Automotive in Phoenix, AZ can help. We may begin with an inspection as part of our auto diagnostics service and evaluate related components within the cooling system service.
A faulty radiator cap can affect how the system maintains pressure and may contribute to overheating concerns over time.
If your cooling system or radiator cap needs to be inspected, call (602) 992-5478 today.
