Dayco Radiator Coolant Hose P/N:70622
Dayco 72340 lower radiator coolant hose for the 2006-2011 Chevrolet Impala V6 3.5L or 3.9L and other vehicles carries coolant between the radiator and the engine.
A lower hose that is wearing out can show up as coolant drips near the front of the car, a low coolant level or overheating. With the engine off and cool, look along the hose for cracks, bulges, soft spots or wet stains. A clamp or radiator connection can leak the same way, so find the source before replacing the hose.
This hose fits the 2006-2011 Chevrolet Impala V6 3.5L or 3.9L, the 2006 Chevrolet Monte Carlo V6 3.9L and the 2006-2007 Monte Carlo V6 3.5L. The listing is one hose, and the fitment calls for one per car.
