The VALUE COLLECTION BD9931N is a heater hose measuring 25 inches in length, designed to carry coolant between the engine and the heater core in automotive and light-duty vehicle heating systems. Heater hoses operate under sustained heat and pressure, making proper material construction and secure connections critical to system reliability. This hose is a direct-replacement style component suited for installation by automotive technicians and experienced DIYers performing cooling system service or heater core repairs.
This hose is appropriate for use in vehicle heating system applications where a 25-inch coolant transfer hose is required. It fits standard heater circuit routing between the engine block or intake manifold and the heater core. Confirm internal diameter, outside diameter, and end configuration against the vehicle or equipment specification before installation.
Designed as a replacement-style heater hose for automotive and light-duty vehicle cooling and heating systems. Verify hose diameter and end fitment against vehicle specifications before installation, as no specific model compatibility data was provided.
Heater hose replacement is typically performed by an automotive technician using basic hand tools including hose clamp pliers and a coolant drain pan. Allow the engine to cool completely before loosening hose clamps or disconnecting any coolant lines to avoid burns from pressurized hot coolant. Inspect hose clamps, fittings, and the heater core inlet and outlet ports for corrosion or damage before installing the new hose. Refill and bleed the cooling system per the vehicle manufacturer procedure after installation.
