Detailed Description

Gates 42357 is an engine water pump engineered for Chevrolet Corvette cooling system maintenance where a reverse-rotation, accessory-belt-driven pump is required. The cast aluminum housing and stamped steel impeller are paired with factory-style fitment for 2014-2019 Corvette models, including 2017-2018 Corvette applications noted without housing. Gates states that each new pump is tested for seal and bearing function and checked for leakage at both the casting and assembled unit level.

This part cross-references GMB 130-3010 for the same application. Use Gates 42357 when replacing a worn or leaking Corvette water pump and restoring coolant flow through the engine cooling circuit.

What This Water Pump Helps Address

• Coolant leaks from a worn pump seal or casting
• Overheating caused by reduced coolant circulation
• Noise from failing pump bearings
• Impeller wear that can reduce coolant movement
• Cooling system service on a Chevrolet Corvette with accessory belt drive

Installation Notes and Tips

Verify reverse-rotation application before installation, since this pump is not timing-belt driven. Confirm whether your Corvette application requires a housing; 2017-2018 Corvette fitment is listed without housing. Inspect the belt drive, pulley alignment, gasket surface, and surrounding cooling components during service to help ensure a proper repair.

Quality Assurance

Gates manufactures this water pump with premium alloy materials and performs functional testing of seals and bearings, along with leakage testing of the casting and assembled pump. The result is an OE-quality fit for select Chevrolet Corvette cooling system repairs.
