Definition

Noun: A radiator hose is a flexible, reinforced tube that carries coolant between a vehicle's engine block and its radiator. It is a critical component of an automobile's cooling system.

Usage

This term is used specifically in automotive contexts to refer to the coolant transfer hose. It is typically modified by "upper" or "lower" to specify its location in the engine bay. * The mechanic recommended replacing the radiator hose as a preventative measure. * A burst radiator hose can cause the engine to overheat rapidly.

Examples

• During the inspection, a small crack was found in the lower radiator hose.
• Coolant was leaking from the connection where the radiator hose attaches to the engine.
• Always check the condition of your radiator hoses when performing seasonal maintenance.

Advanced Usage

• Upper radiator hose: Typically carries hot coolant from the engine to the top of the radiator.
• Lower radiator hose: Typically carries cooled coolant from the bottom of the radiator back to the engine. It often contains a spring to prevent collapse under suction.

Variants and Related Words

• Heater hose: A similar, often smaller, flexible hose that carries coolant to and from the vehicle's heater core inside the cabin.
• Coolant hose: A more general term that can encompass radiator hoses, heater hoses, and other coolant-carrying lines.

Antonyms

• There is no direct antonym, as it is a specific mechanical part. A contrasting component might be a solid coolant pipe or metal coolant line, which are not flexible hoses.
