Detailed Product Description

The Dorman 626-674 radiator coolant hose is engineered as a molded assembly, combining EPDM rubber, metal, and plastic materials to withstand the thermal and mechanical stresses of the cooling system in Toyota RAV4 vehicles. The hose features a protective sleeve to guard against abrasion and environmental damage, extending service life. Its design includes three different inside diameters (40mm, 37mm, and 25mm) to accommodate various connection points within the cooling system. With a maximum working pressure of 75 PSI and a working pressure rating of 50 PSI, this hose supports efficient coolant flow under typical operating conditions. The hose’s maximum bend angle of 90 degrees and bending radius of 3 allow for precise installation without kinking or restricting coolant flow. The overall centerline length of approximately 3628 mm and two-branch configuration ensure compatibility with the Toyota RAV4 cooling system layout.

Common Applications and Problem Resolution

• Replacement of worn or cracked radiator coolant hoses in Toyota RAV4 models
• Resolving coolant leaks caused by hose deterioration or damage
• Addressing overheating issues due to restricted or collapsed hoses
• Restoring proper coolant circulation to maintain engine temperature
• Upgrading to a molded assembly hose for improved fit and durability

Installation Notes and Tips

When installing the Dorman 626-674 radiator coolant hose, ensure the vehicle is cool and the cooling system is depressurized. Verify the hose orientation matches the molded assembly shape and branch configuration. Use appropriate clamps to secure hose ends with inside diameters of 40mm, 37mm, and 25mm. Avoid sharp bends beyond the 90-degree maximum bend angle to prevent hose damage or flow restriction. Inspect the protective sleeve for proper positioning to maximize abrasion resistance during installation.
