Detailed Product Description
Dayco’s Curved Radiator Hose line focuses on formed coolant hoses that follow the routing needed in demanding engine compartments. This Dayco 70924 engine coolant bypass hose is made from EPDM, a material commonly used in cooling-system hoses for its resistance to heat and coolant exposure. The curved shape and matching 1 3/4-inch end diameters help maintain a secure connection where a bypass hose is specified.
This hose is a practical choice for service work on Chrysler, General Motors, and Navistar applications that call for this configuration. It also cross-references ACDelco 20014S for the same application. If you are replacing a worn coolant hose on a Chrysler or GM vehicle, Dayco 70924 offers the correct hose style and sizing for the cooling circuit.
What This Hose Helps Address
- Coolant leaks caused by cracked or aged rubber hose material
- Restricted coolant flow from a softened or collapsed bypass hose
- Improper hose routing in curved cooling-system runs
- Loss of sealing at 1 3/4-inch hose connections
- Cooling-system service needs on Chrysler, GM, and Navistar vehicles
Installation Notes and Tips
Inspect the mating tubes, clamps, and nearby cooling components before installation. Confirm the hose routing matches the original curved path and verify both connection points are clean and free of corrosion or residue. Because this hose does not include a heat shield or protective sleeve, make sure surrounding components do not create unnecessary abrasion or heat exposure.
For fitment-based searches, this Dayco 70924 hose is used in Chrysler, GM, and Navistar cooling-system applications where a 1 3/4-inch curved bypass hose is specified. Always match the hose shape and inside diameter to the original part before installation.
Quality Assurance
This hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC standards, supporting consistent material and performance requirements for coolant hose service. Dayco 70924 is built as a cooling-system replacement part for the specified application.
