Technical Service Bulletin – Part No. US8918

To support proper installation and long-term performance of the US8918 water pump, we have released a new Technical Service Bulletin highlighting several critical installation procedures that should always be followed during service.

The US8918 is one of our most widely used water pumps, and proper installation practices play an important role in ensuring reliable operation and preventing premature cooling system issues. This bulletin focuses on key areas, including:

• Using the correct coolant type and replacing contaminated coolant
• Proper mounting bolt torque specifications
• Correct threadlocker application
• Proper cooling system bleeding and air removal procedures

Following these installation guidelines can help improve cooling system performance, support long-term durability, and reduce the risk of common installation-related issues.

Please review the attached bulletin carefully before installation and share it with your service technicians and installers as needed.

Thank you for your continued support of US Motor Works products.
