Dayco 71164 Radiator Coolant Hose - Filler Tank, Upper or Upper - Pipe To Radiator

Dayco Curved Radiator Hose 71164

Dayco 71164 is a curved radiator coolant hose built for upper cooling-system routing on select Nissan applications. Made from EPDM rubber with a black finish, it uses a single I.D. hose design and matches the specified 1 1/16-inch inside diameter at both ends for a direct replacement profile.

Compatible With 1982-1986 Nissan Sentra, 1983-1986 Nissan Pulsar NX, and 1983 Nissan Pulsar upper radiator hose applications, this hose is specified for the cooling path between the pipe and radiator where a formed hose shape is required. The Dayco Curved Radiator Hose line focuses on application-specific routing and OE-style dimensions for service replacement.

Key Features

• EPDM construction for cooling-system use
• Black curved radiator hose profile
• Single I.D. hose design
• 1 1/16-inch inside diameter at both ends
• Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
• Fits upper radiator hose routing on select Nissan models

Detailed Description

Dayco 71164 is a radiator coolant hose engineered for upper cooling-system service where a curved hose shape is needed to follow the factory routing. Its EPDM material is suited to coolant exposure and underhood temperatures, while the formed profile helps maintain the correct path between the engine-side pipe and the radiator connection. This part cross-references Gates 21029 for the same application.

Vehicle fitment includes 1982-1984 Nissan Sentra upper, 1985-1986 Nissan Sentra upper - pipe to radiator, 1983-1986 Nissan Pulsar NX upper, and 1983 Nissan Pulsar upper. If you are searching for a Dayco 71164 radiator hose for Nissan Sentra or a curved upper hose for Nissan Pulsar NX, this part matches those listed applications.

What It Helps Address

• Coolant leaks from a cracked or aged upper radiator hose
• Softening, swelling, or collapse of the original hose
• Improper hose routing caused by a misshaped replacement
• Cooling-system service on Nissan Sentra and Nissan Pulsar models
• Loss of coolant flow through the upper radiator connection

Installation Notes and Tips

Verify the hose path, end diameters, and routing before installation. Confirm that the application is an upper radiator hose or upper pipe-to-radiator hose for the listed Nissan model and year. Inspect adjoining fittings, clamps, and the radiator neck for wear or corrosion before installing Dayco 71164.

Quality Assurance

This hose is built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and performance requirements for radiator coolant hose service.
