The ACDelco Gold 252-1027 (19382527) is a premium aftermarket engine water pump designed to circulate coolant and restore proper engine temperature control with OEM-style fit and durability.

When your vehicle requires a dependable replacement cooling pump, the ACDelco Gold 252-1027 offers a complete aftermarket solution engineered for many GM and non-GM applications. Built with heat-treated shafts, sealed bearings, and coated sealing surfaces, this water pump is supplied with the necessary gaskets, O-rings, and seals to simplify installation and reduce the chance of leaks. The component aims to match the original equipment’s dimensions and performance so mechanics and DIYers can replace a failed pump with confidence.

How does this water pump keep my engine running at the right temperature?

The pump forces coolant through the engine block and radiator to dissipate heat, maintaining a stable operating temperature. Its bearing and shaft design are optimized for continuous rotation, while precision seals limit coolant loss and air entry.

• High-quality permanently sealed bearings for extended life
• Heat-treated shaft assembly for increased strength under load
• Coated seals to resist wear and reduce leakage risk
• Complete gasket and O-ring kit included for a sealed installation

Will this ACDelco Gold pump fit my vehicle and replace the original part?

This water pump is manufactured to match form, fit, and function for the vehicle applications listed for part 252-1027 (19382527). It is intended as a direct replacement where the original pump specification aligns with ACDelco’s part number.

• Designed for GM vehicles and many non-GM makes that share the same pump specification
• OEM-style mounting points and shaft dimensions for straightforward replacement
• Supplied with all necessary seals and gaskets to aid proper installation
• Tested for leak resistance and operational reliability prior to packaging

What construction and materials make this model durable?

Durability comes from a combination of material choices and manufacturing processes: a heat-treated shaft resists bending and wear, while sealed bearings and coated sealing surfaces reduce friction and fluid loss. These features extend the operating life compared with untreated or lower-grade replacements.

• Heat-treated shaft assemblies for enhanced fatigue resistance
• Sealed, lubricated bearings to minimize friction and maintenance
• Coated seals for improved longevity in thermal cycling conditions
• Quality-controlled assembly and testing to reduce early failures

How does the included hardware make installation easier?

ACDelco supplies gaskets, O-rings, and seals with the pump so you receive a full replacement kit rather than just the pump housing. This reduces the chance of missing parts and helps ensure a leak-free seal when fitted correctly.

• Pre-packaged gasket set tailored to this pump’s mating surfaces
• O-rings sized to seal coolant passages and prevent air entry
• Replacement seals that match the pump’s coatings and tolerances
• Simplifies repair jobs by eliminating the need to source separate sealing components

Who is this for: The ACDelco Gold 252-1027 (19382527) water pump is suited to vehicle owners, independent mechanics, and repair shops seeking a high-quality aftermarket replacement that mirrors OEM fit and function. It’s a practical choice when the original pump has failed, is leaking, or when performing scheduled cooling-system maintenance and you want a durable, tested replacement with all necessary installation parts included.
