Dayco 70468 Engine Coolant Bypass Hose

Dayco 70468 Curved Radiator Hose

The Dayco 70468 curved radiator hose is an engine coolant bypass hose built for specific Dodge applications. Made from EPDM rubber in black, it uses a single I.D. hose design with 13/16-inch inside diameter ends for a direct-fit cooling system connection.

Compatible with 1964-1969 Dodge Dart, 1967-1969 Dodge Charger, and 1969 Dodge Monaco, this hose supports the coolant routing used in these vehicles. The Dayco Curved Radiator Hose line is engineered for formed hose applications where a shaped coolant path is required to match the vehicle’s original routing.

Detailed Description

This Dayco 70468 engine coolant bypass hose is specified for Dodge Dart, Charger, and Monaco models listed in the fitment data. Its curved shape helps maintain the original coolant path in applications that require a formed hose rather than a straight universal section. The EPDM material is commonly used in cooling system hoses for its resistance to heat and coolant exposure, while the SAE J20R4 Class D-1 and SAE J1684 Type EC specifications provide a clear reference for hose construction requirements.

This part cross-references Gates 20522 and NAPA 7334 for the same application. If you are searching for a curved radiator hose for a 1964-1969 Dodge Dart, 1967-1969 Dodge Charger, or 1969 Dodge Monaco, Dayco 70468 is the direct part number to verify against your cooling system layout.

What It Helps Address

• Coolant routing issues caused by a worn or incorrect bypass hose
• Leaks from cracked, hardened, or deteriorated rubber hose material
• Improper hose shape that does not follow the original engine bay path
• Cooling system service needs on Dodge Dart, Charger, and Monaco applications
• Replacement of a formed hose with the correct inside diameter and curvature

Installation Notes and Tips

Verify the hose routing, end diameter, and formed shape against the original part before installation. Confirm that the hose path clears nearby components and that the cooling system is fully drained and refilled according to service procedures. Inspect clamps, necks, and adjoining coolant passages for wear or corrosion before installing the new hose.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, providing a defined standard for cooling system hose construction. Part number 70468 is listed for the Dodge Dart, Dodge Charger, and Dodge Monaco applications shown in the fitment data.
