Product Details
Dayco Curved Radiator Hose 71719 is engineered for upper radiator coolant transfer in vehicles that require a curved hose layout. The EPDM rubber construction is suited for cooling system temperatures and coolant exposure, while the protective sleeve adds an extra layer where the hose passes near surrounding components. This hose is a direct service part for 1992-1994 Chevrolet Astro, upper, and 1992-1994 GMC Safari, upper. It also cross-references ACDelco 26342X for the same application.
What This Hose Helps Address
- Upper radiator hose cracking from age and heat cycling
- Coolant leaks at the hose body
- Softening or swelling from prolonged coolant exposure
- Chafing where the hose routes near engine components
- Restricted coolant flow caused by a deteriorated hose
Installation Notes and Tips
Verify the hose routing and end diameters before installation. Confirm the upper hose path on 1992-1994 Chevrolet Astro and 1992-1994 GMC Safari models, then inspect the radiator neck and engine connection points for corrosion, residue, or damage before clamping the new hose in place. Use fresh coolant and bleed the cooling system according to the vehicle service procedure after installation.
