Dayco 71367 Radiator Coolant Hose - Lower or Upper

Curved Radiator Hose for Saab and GM Applications

Dayco 71367 is a curved radiator coolant hose built for upper and lower cooling-system routing where a formed hose is required. Made from EPDM with a black finish, it uses a protective sleeve and meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for cooling-system service.

This Dayco Curved Radiator Hose line is engineered for precise hose routing in applications that need a shaped replacement rather than a straight universal hose. The 71367 part number is listed for select Saab 9-3 and Saab 900 upper hose applications, along with several 1987-1988 GM compact car lower hose applications.

Key Features

• EPDM construction for radiator coolant service
• Black finish for OE-style appearance
• 1 1/4 in. inside diameter at both ends
• Single I.D. hose design
• Protective sleeve included
• Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
• Curved hose profile for routed cooling-system layouts

Detailed Description

Dayco 71367 is a formed radiator coolant hose designed for vehicles that require a curved upper or lower hose with matching 1 1/4 in. end diameters. The EPDM rubber construction is suited for coolant exposure and underhood temperature cycling, while the protective sleeve adds an extra layer where the hose passes near adjacent components. This hose is a direct-fit style replacement for select Saab 9-3 and Saab 900 upper radiator hose applications, as well as 1987-1988 Buick Skylark, Oldsmobile Calais, Oldsmobile Cutlass Calais, and Pontiac Grand Am lower radiator hose applications.

Cross-reference part numbers include Gates 21701 and NAPA 8391 for the same application. Dayco 71367 is also associated with interchange numbers such as ACDelco 26151X and General Motors 22532336.
