What It Helps Fix

• Coolant leaks from a cracked or aged lower radiator hose
• Softening, swelling, or collapse in the original hose
• Poor hose routing after prior cooling-system repairs
• Loss of coolant flow caused by a damaged molded hose shape
• Overheating concerns related to hose deterioration

Installation Notes

Verify hose routing, end diameters, and centerline length before installation. This molded hose is shaped for lower radiator hose placement and should be matched to the vehicle’s original cooling-system layout. Inspect adjoining clamps, radiator necks, and engine fittings for wear or corrosion before installing the replacement hose.
