Gates 44085 Engine Water Pump

Gates Water Pump for Toyota and Lexus Timing Belt Engines

The Gates 44085 engine water pump is built for timing belt driven cooling systems in select Lexus and Toyota applications. It uses a cast aluminum housing, a plastic impeller with reverse rotation, and a pulley included for a direct replacement setup.

Key Features

• Cast aluminum housing for durable cooling system service
• Plastic impeller with reverse rotation design
• Timing belt driven water pump with pulley included
• Outlet quantity: 1
• Includes water pump, metal gasket, gasket, 2 O-rings, 6 bolts, and 6 plain washers
• OE-quality fit from Gates Water Pump (Standard) line

Product Details

Gates Water Pump (Standard) part number 44085 is engineered for vehicles that use a timing belt driven pump in the cooling system. The pump is manufactured with premium alloy materials and is tested for seal and bearing function as well as leakage at both the casting and assembled pump stages. This makes it a practical replacement for Lexus LS430, Lexus SC430, Toyota 4Runner, Toyota Sequoia, Toyota Tundra, and other listed applications that require a reverse-rotation timing belt water pump. This part cross-references Airtex AW9476 and Dayco DP1319 for the same application.

• Overheating caused by reduced coolant circulation
• Timing belt service replacement on Lexus and Toyota engines
• Cooling system maintenance on interference engine applications

Installation Notes and Quality Assurance

Confirm reverse-rotation and timing belt driven specifications before installation. Replace the pump during timing belt service when the vehicle calls for it, and inspect the mating surfaces, gasket areas, and O-ring locations for cleanliness before assembly. Gates tests seals, bearings, and leakage on each new water pump to support consistent operation in the cooling system.

The Gates Water Pump (Standard) line is positioned as an OE-quality replacement option for select Lexus and Toyota vehicles, including applications such as the Lexus LS430, Lexus SC430, and Toyota Tundra. Part number 44085 is built to match the listed fitment and cooling system requirements.
