How does this water pump match original equipment standards?

OAW engineered the F1670 to mirror OE dimensions and performance so installation and operation match the factory pump. The housing, impeller alignment, and shaft tolerances are designed to integrate with your engine’s existing mounting and coolant pathways.

• Compatible impeller and shaft alignment for factory belt and pulley fits
• Supplied gasket to ensure a proper seal and reduce installation steps

What are the practical benefits of replacing your pump with the OAW F1670?

Swapping in a reliable, OE-style water pump restores coolant circulation and helps prevent overheating, leaks, and premature accessory wear. Using a pump built to original specifications simplifies repair time and reduces the risk of fitment or sealing issues after installation.

• Reduces risk of coolant leaks with included gasket
• Restores correct coolant flow for temperature stability
• Eliminates fitment guesswork thanks to OE-compatible design

How should I prepare for installation and what should I check afterward?

Prepare by draining the cooling system, removing the drive belt and pulley as required, and cleaning the mounting surface. After fitting the OAW F1670 and new gasket, refill with fresh coolant and run the engine to check for leaks and proper temperature stabilization.

• Drain coolant and disconnect battery before starting work
• Inspect pulley, belt, and thermostat during replacement
• Test for leaks and correct thermostat operation after installation
