Gates 43187 Engine Water Pump

Engine Water Pump Overview

This Gates engine water pump, part number 43187, is built for accessory-belt-driven cooling systems that require a standard rotation pump. It is a direct replacement style water pump for heavy-duty Ford applications and related commercial platforms, with fitment covering multiple Super Duty trucks and chassis models.

Key Features

• Cast aluminum housing for strength and corrosion resistance.
• Plastic impeller with standard rotation for proper coolant circulation.
• Accessory belt drive type for non-timing-belt applications.
• Includes the water pump seal.
• 100% seal, bearing, and leakage testing during manufacturing.

Detailed Description

Gates Water Pump 43187 is engineered as a standard replacement for vehicles using an accessory belt drive and a non-timing-belt layout. The cast aluminum housing and plastic impeller provide a practical balance of durability and efficient coolant movement, while the standard rotation design matches the original cooling system configuration. This part number 43187 is listed for Ford E-350 Super Duty, Ford F-250 Super Duty, and Ford F-350 Super Duty applications, along with additional Ford commercial chassis and bus platforms. It also cross-references LC3Z 8501 A for the same application.

What It Helps Address

• Coolant circulation problems caused by a worn pump.
• Leakage from failed seals or housing wear.
• Noise or rough operation from bearing wear.
• Cooling system performance loss in accessory-belt-driven setups.
• Replacement needs for standard-rotation water pump applications.

Installation Notes and Quality Assurance

Verify the drive type, rotation, and application before installation. This pump is not timing-belt driven and does not include a pulley, fan clutch, or thermostat housing. Gates tests every new pump for seal and bearing function and performs leakage checks on both the casting and assembled unit. Part number 43187 is manufactured to OE-quality fit standards for the listed Ford and commercial applications.
