Sejaede Water Pump Thermostat Kit for Buick/Chevrolet 1.4L – AW6662 Direct-Fit, Includes Seals

If your Encore, Cruze, Sonic, or Trax with a 1.4L engine needs a dependable cooling system service, this all-in-one kit includes the engine water pump, compatible thermostat, and the seals required for a single-shop installation. The kit replaces OE part numbers such as 55486342, 28290034, 252996 and others, making it straightforward to match to service guides and repair manuals. Built with corrosion-resistant materials and a precision-balanced impeller, the components aim to provide leak-resistant operation and stable coolant flow under typical driving conditions.

How does this kit match my vehicle and original equipment numbers?

The Sejaede kit is offered to fit specific model years and OE reference numbers so you can confirm compatibility before buying. It’s intended for Buick Encore (2013–2021) and multiple Chevrolet 1.4L applications including Cruze, Cruze Limited, Sonic, and Trax across the listed years. The package lists many equivalent part numbers for both the water pump and thermostat to make cross-referencing easier.

• Vehicle fit: Buick Encore L4 1.4L (2013–2021)
• Chevrolet fit: Cruze, Cruze Limited, Sonic, Trax (selected years)
• Water pump OE matches: AW6662, 55486342, 25192709, 55484625, 55561623, and more

What performance features does the water pump provide?

The pump in this kit uses a precision-balanced impeller and reinforced housing to keep coolant moving consistently through the engine’s passages. That helps the cooling system maintain normal operating temperature under everyday driving and during longer runs, while the materials are selected to resist corrosion and reduce risk of leaks.

• Precision-balanced impeller for steady coolant flow
• Reinforced, corrosion-resistant housing for durability
• Pressed-on shaft assembly to hold tolerances under load
• Seals included to reduce the chance of installation leaks

What comes in the kit and how does it simplify installation?

This is a direct-replacement kit that groups the water pump, thermostat, and the necessary seals and hardware so you don’t have to source multiple parts. That reduces the risk of missing components, shortens repair time, and lowers the chance of secondary disassembly if an omitted seal is discovered later.

• Engine water pump pre-assembled to specified tolerances
• Coolant thermostat matched to OE numbers
• Required gaskets and seals for a single-install job
• Compatibility list to confirm fit before you begin

How long should I expect these components to last and when to inspect them?

Longevity depends on driving conditions, coolant maintenance, and proper installation. Regular coolant flushes, correct coolant type, and routine visual checks for leaks or bearing noise will help extend life. If you notice coolant loss, overheating, or unusual engine bay noises, inspect the pump and thermostat promptly.

• Perform visual checks during scheduled maintenance intervals
• Replace if leaks, bearing noise, or overheating symptoms appear
• Use recommended coolant and follow manufacturer service intervals
• Kit reduces rework by including seals and matched thermostat

Who is this for: The Sejaede AW6662 water pump and thermostat kit is tailored for DIY mechanics and professional technicians working on Buick Encore and specified Chevrolet 1.4L vehicles who want a direct-fit replacement that matches OE part references. Choose this kit if you need a single-supplier solution with included seals to streamline installation and reduce the chance of missing parts during a cooling-system service.
