Your vehicle’s cooling system is essential for keeping the engine at a safe operating temperature. If this system fails, your engine can quickly overheat, leading to severe damage. While some symptoms may seem minor at first, ignoring them can result in a breakdown or even engine failure. To avoid major issues, it's important to recognize and address cooling system problems early. At Yanis Foreign Auto Repair, we provide expert European cooling system repair in the greater Hyannis area. Here are four common cooling system issues that should be fixed as soon as they appear.


Overheating Engine

One of the most obvious signs of a cooling system problem is an engine that overheats. If the temperature gauge climbs into the red zone or you see steam coming from under the hood, you need to act quickly. Overheating can be caused by a variety of issues, including low coolant levels, a stuck thermostat, or a failing water pump. Continuing to drive with an overheating engine can lead to warped cylinder heads, a blown head gasket, or even total engine failure.


Coolant Leaks

If you notice puddles of coolant under your vehicle, you likely have a leak that needs to be addressed ASAP. Coolant leaks can occur in places such as the radiator, hoses, and water pump. Even a small leak can cause coolant levels to drop and reduce the system’s ability to control temperature. Leaking coolant is also harmful to pets and the environment, so it’s important to have any leak identified and repaired immediately.


Faulty Thermostat

The thermostat regulates the flow of coolant through the engine. If it gets stuck in the closed position, it will prevent coolant from circulating and cause the engine to overheat. Replacing a faulty thermostat is a relatively straightforward fix that can restore proper engine temperature regulation.


Radiator Problems

The radiator plays a central role in the cooling system by dissipating heat from the coolant. If the radiator becomes clogged, corroded, or develops cracks, it won’t be able to cool the engine effectively. Prompt inspection and repair of radiator issues are essential to prevent more serious engine trouble.
