Show original supplier description
The ACDelco 252-499 is a Professional™ Engine Coolant Water Pump that circulates coolant through your vehicle's radiator and engine system to maintain optimal engine temperature and performance. Constructed with an aluminum housing and a grey iron impeller featuring 10 vanes, this water pump is designed for durability. It utilizes a timing belt for its drive type and has a standard impeller rotation. The housing material is aluminum, and it includes a grey iron impeller. Key specifications include a hub height of 70.86 mm and an impeller vane quantity of 10. While mounting hardware, pulley, and fan clutch are not included, the product is thoroughly tested for reliable, leak-free performance. The manufacturer recommends pressure-testing the system for leaks after installation and checking for sufficient fan blade clearance. This water pump is compatible with a wide range of GM and non-GM vehicles. Specific fitments include Lexus ES300 (1994-2003), ES330 (2004-2006), RX300 (2000-2003), RX330 (2004-2006), and RX400h (2006-2008); Toyota Avalon (1995, 1999-2004), Camry (1994-1995, 1999-2006), Highlander (2001-2010), and Sienna (1999-2006).
