Engine overheating can be one of many signs there may be trouble with your vehicle's radiator or coolant system, and if not checked with automotive service can lead to irreparable engine damage.

​

COMMON ISSUES THAT CAN CAUSE YOUR VEHICLE TO OVERHEAT

• Low engine coolant: Radiator systems can leak for many reasons, such as corrosion or impact from small rocks and road debris.

• Blocked coolant flow: Sediments and foreign objects in the radiator, head gasket, and other spots can prevent coolant from circulating.

• Broken or stuck thermostat: The engine thermostat can fail or become locked in the closed position.

• Broken radiator parts: These include the water pump and radiator fan.

​

SYMPTOMS OF A FAILING COOLING SYSTEM

• High dashboard temperature gauge: When you see this alert we recommend pulling over before the engine overheats.

• Visible coolant leak: A bright-green, sweet-smelling stain on your driveway or garage floor.

• White steam from hood: The most dramatic sign of a cooling system failure is, of course, white steam rising from under your hood: your engine is already overheating.

• White exhaust smoke: White smoke from your exhaust pipe suggests that your engine is burning coolant. Catastrophic engine damage is a possibility.
