This product line emphasizes durability and compliance with industry SAE standards, providing a reliable solution for maintaining proper coolant flow and temperature regulation in compatible vehicles.

Technical Description and Specifications

The Dayco 70924 hose is manufactured from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, making it suitable for engine cooling applications. Both ends of the hose have an inside diameter of 1 3/4 inches, ensuring a consistent and secure connection. The hose does not include a heat shield or protective sleeve, which is typical for this type of engine coolant bypass hose. Its single inside diameter design simplifies installation and fitment in compatible cooling systems.

Common Applications and Problem Solving

• Replacement for worn or cracked engine coolant bypass hoses
• Prevents coolant leaks that can cause engine overheating
• Restores proper coolant flow in vehicles requiring a 1 3/4 inch diameter hose
• Addresses hose degradation due to heat and chemical exposure
• Supports maintenance of engine temperature regulation systems

Installation Notes and Tips

Ensure the hose ends are clean and free of debris before installation. Verify the 1 3/4 inch inside diameter matches the vehicle’s coolant bypass connections. Since this hose does not include a heat shield or protective sleeve, consider routing it away from high-heat components to prolong service life. Proper clamping is essential to prevent leaks and maintain system pressure.
