Compatible With Ford Bronco, Ford E-Series vans, and Ford F-Series trucks across the listed applications, this water pump is a direct-fit replacement for service work where OE-style performance is required. The SK1251390 part number is also referenced by several aftermarket cross numbers for the same application.

Key Features

• Engine water pump for cooling-system circulation.
• Manufactured with high-quality materials and precision engineering.
• Tested to meet or exceed OE specifications.
• Supports consistent coolant flow through the engine and radiator.
• Direct-fit replacement for listed Ford applications.

Detailed Description

The SKP SK1251390 water pump is engineered for Ford cooling-system service on Bronco, E-Series, and F-Series applications listed in the fitment data. It is intended to restore coolant circulation and help control engine temperature when the original pump shows wear, leakage, or reduced flow. The SK1251390 is built and tested to OE-level standards so it matches the expected fit and function for the specified vehicles.

This part cross-references Airtex AW4030N and GMB 125-1390 for the same application.

Common Replacement Reasons

• Coolant circulation has dropped and engine temperature is rising.
• Visible leakage from the pump housing or weep area.
• Noise from a worn pump bearing or impeller assembly.
• Temperature fluctuations during idle or load changes.
• Cooling-system service on a listed Ford truck or van.

Installation Notes

Verify engine and emission-system details against the fitment notes before ordering, especially for 1976-1977 applications with California emission system requirements and serial-number restrictions. Confirm gasket surfaces, pulley alignment, and coolant condition during installation. Use the vehicle service procedure for torque and refill specifications.

Quality Assurance

SKP states that this water pump is tested to meet or exceed Original Equipment specifications for fit and performance.
