A radiator hose carries coolant between the engine and the radiator. A lower hose that is cracked, swollen, soft or seeping at its ends can let coolant escape. If the original lower hose shows those signs, this Dayco hose is designed to replace it. Check the vehicle's service information for the correct clamps and whether they may be reused. Then refill and bleed the cooling system as it directs. Country of origin: Mexico.
