Designed for the Evo 8 4G63

The 4G63 turbocharged engine in the Evo 8 relies on consistent coolant circulation to control operating temperatures. The water pump moves coolant through the engine and cooling system as the engine operates.

The Gates 42577 is designed around the Evo 8 application, providing an OE-style replacement without requiring a custom cooling-system conversion.

It is a suitable choice for street cars, performance builds, engine rebuilds, and preventative maintenance.

Water Pump for Timing-Belt Service

The water pump is located within the timing-system area of the 4G63 engine. Because of this, many Evo owners choose to replace the water pump while performing timing-belt maintenance.

Firstly, replacing related components at the same time can reduce repeated labor. Secondly, installing a fresh water pump helps refresh an important part of the cooling system. Thirdly, using a properly matched pump helps maintain the intended coolant circulation for the engine.

If your Evo 8 is already undergoing major timing-system service, inspecting the water pump is a sensible part of the process.

Includes Gasket and O-Ring

Gates 42577 is commonly supplied as a complete water-pump package with the necessary sealing components. Current Evo-specific listings specify that the package includes:

• 1 × Gates Water Pump
• 1 × Water Pump Gasket
• 1 × Water Pipe O-Ring

This helps simplify installation and reduces the need to purchase the basic sealing components separately.

Always verify the contents of the package supplied at the time of purchase.

Gates OE-Replacement Construction

Gates describes its water pumps as being manufactured with premium materials and tested for proper function and leakage. The 42577 uses a cast-aluminum housing and stamped-steel impeller, with the pump designed to meet OE replacement requirements.

Gates also states that its pumps undergo functional and leakage testing of components such as seals, bearings, castings, and the assembled pump.

For an Evo 8 owner looking for a replacement water pump without moving to a custom cooling-system setup, the 42577 offers a straightforward option.
