Dayco Radiator Coolant Hose P/N:72627
Dayco 72221 lower radiator coolant hose for the 2005-2010 Jeep Grand Cherokee V6 3.7L and other vehicles carries coolant between the radiator and the engine.
A collapsed or swollen hose, coolant residue at the ends, or an engine that runs hot can mean this hose is worn, though a thermostat or a radiator cap can be behind the overheating too, so find the cause before replacing anything.
This hose fits the 2005-2010 Jeep Grand Cherokee V6 3.7L and the 2006-2010 Jeep Commander V6 3.7L. Both take one lower hose, and this listing is one piece.
