Dayco Radiator Coolant Hose P/N:70155
Dayco 71986 upper radiator coolant hose for the 2000-2003 Ford Excursion V8 7.3L, the 2000-2005 Excursion V8 5.4L or V10 6.8L and other vehicles joins the coolant reservoir to the radiator. This Dayco radiator coolant hose carries engine coolant between those two points.
Coolant residue at the hose ends, a swollen, soft or cracked hose, or a temperature gauge that climbs can mean this hose is worn, though a loose clamp or a tired radiator cap can be behind the same symptoms. Look at the hose only with the engine off and cool.
Sold as a single hose, this radiator coolant hose is the upper line for the 1999-2002 Ford F-250 Super Duty V8 5.4L, the 1999-2003 F-250 Super Duty V8 7.3L, the 1999-2004 F-250 Super Duty V10 6.8L and the 2004 F-250 Super Duty V8 5.4L, and for the 1999-2003 Ford F-350 Super Duty V8 7.3L and the 1999-2004 F-350 Super Duty V8 5.4L or V10 6.8L, with one hose per vehicle.
