Keep coolant moving between the radiator and engine with the Gates Radiator Coolant Hose 21826 — the LOWER radiator hose in the cooling circuit. It installs as a direct-fit replacement for the 1984-1989 Chevrolet P20, 1984-1994 Chevrolet P30, 1984-1989 GMC P2500, 1984-1994 GMC P3500, 1992-1993 Chevrolet G20, 1992-1993 Chevrolet G30, 1992-1993 GMC G2500 and 1992-1993 GMC G3500.
Coolant hoses harden, crack, swell, or seep with age and heat cycles. Signs this hose may need replacing include visible coolant leaks or drips near the lower radiator connection, a soft or bulging hose, low coolant, or engine overheating. If a failed lower radiator hose is the cause of your coolant loss, this replaces it — diagnose the source of any overheating before ordering, since other cooling components can be involved.
