One of the most important parts on your Lexus is also one of the simplest. It's your Lexus water pump, and without it, you're going to be boiling over in no time. Ironically enough, your Lexus water pump is also responsible for you getting heat in your car during the winter, so the Lexus water pump is tasked with keeping you warm and your engine cool. The Lexus water pump accomplishes these seemingly incongruous tasks by circulating the coolant through your engine, radiator, and heater core. We say the Lexus water pump is simple because it consists of a housing, an impeller, and a shaft. That's it. Sure, there are some bearings and seals and stuff, but your Lexus water pump doesn't have any electronic gizmos helping it do its thing. But the Lexus water pump is turning whenever your engine is running, so after a while, the bearing surfaces and seals get worn. When that happens, the Lexus water pump can't turn freely, or it begins to leak coolant. That's when it's time to replace your Lexus water pump. And you can replace your Lexus water pump with a new or remanufactured Lexus water pump from us. Shopping here will save you a ton of money versus the dealership, and you won't have to wait a month for your Lexus water pump like you would at the local parts chain. Even better, you'll get an OE-quality Lexus water pump or Lexus auxiliary water pump that will last just as long as your original.
