ACDelco Gold Engine Water Pump 252-994 (19357961) with Gaskets & Sealed Bearings — OE Fit, Durable

The ACDelco Gold 252-994 (19357961) Engine Water Pump is a premium aftermarket pump designed to circulate coolant reliably and replace the OE unit with proper fit, seals, and installation hardware included.

This ACDelco Professional water pump is built for drivers and technicians who need a durable replacement that matches the form, fit, and function of the original equipment. It ships with gaskets, seals, and O-rings so you have the parts required for a clean installation, and it’s engineered with treated shafts, sealed bearings, and coated sealing surfaces to withstand routine driving conditions and temperature cycling.

How does this pump maintain engine temperature?

The pump moves coolant from the engine block to the radiator and back, creating a steady flow that helps the cooling system remove heat efficiently. Its sealed-bearing design and optimized impeller ensure consistent flow rates across typical engine speeds without introducing leaks or vibration.

• High-quality permanently sealed bearings reduce friction and maintenance.
• Heat-treated shaft assembly resists wear and deflection under load.
• Precision-molded impeller design promotes steady, balanced coolant circulation.
• Included gaskets and O-rings ensure leak-free sealing at mating surfaces.

Will this pump fit my vehicle and replace the original unit?

ACDelco Gold pumps are produced to match the physical dimensions and mounting patterns of the factory component so they can serve as direct replacements for many models. This specific part number covers GM applications and a variety of non-GM vehicles where the OE part number cross-references.

• Manufactured to OE-equivalent form and mounting geometry.
• Supplied with installation hardware to simplify replacement.
• Cross-referenced to original part numbers for correct application.

What design features improve durability and long-term performance?

This water pump incorporates several enhancements aimed at extending service life under normal driving conditions. Coated seals and heat-treated internal components help resist corrosion, wear, and thermal stress while the permanently lubricated bearings lower the chance of premature failure.

• Coated sealing surfaces for improved longevity against coolant exposure.
• Heat-treated shafts for higher fatigue resistance than untreated assemblies.
• Sealed, lubricated bearings for reliable operation and reduced maintenance.
• Tested for leak-free performance before shipping.

How does installation readiness help reduce shop time?

The pump is packaged with the necessary gaskets, seals, and O-rings so you don’t have to source multiple items before starting the job. This reduces vehicle downtime and helps ensure you achieve correct sealing during reassembly, especially when replacing the pump during routine cooling-system service.

• All required seals included for a single-stop installation.
• Pre-tested parts minimize troubleshooting after fitment.
• Designed to match OE connections to simplify hose and belt alignment.

Who is this for: The ACDelco Gold 252-994 (19357961) Engine Water Pump is aimed at professional mechanics, independent shops, and DIY enthusiasts who want a high-quality replacement that mirrors original equipment performance. It’s a good choice when you need a reliable, tested pump with included hardware to complete a coolant-system repair promptly and with minimal additional parts sourcing.
