Gates Engine Auxiliary Water Pump,Engine Water Pump P/N:43327BH
Gates 44050 water pump for the 2006-2015 Lexus IS250 V6 2.5L and other vehicles moves coolant through the engine and its cooling system.
Coolant seeping from the pump, a whine or grinding from the bearing, or an engine running hot can mean the pump is wearing out. A thermostat, radiator, hose or drive belt can be behind overheating too, so find the cause before buying. One pump goes on each engine.
This accessory-belt-driven water pump also fits the 2013-2018 Lexus GS450h V6 3.5L and the 2016-2018 Lexus IS300 V6 3.5L, and it is built to fit and perform to OE specifications.

How are Gates water pumps tested?
Every pump gets a functional test of its seals and bearings and a leakage test of the casting and of the assembled pump, both at 100 percent.

It can be. Coolant seeping from the pump or a whine from the bearing can mean the pump is wearing out, and a shop can test the cooling system if you're unsure.
