Because it is bi-directional, it can be installed to accommodate either engine rotation, which simplifies stocking and installation compared to a rotation-specific pump. The pump body and internal components are constructed of metal for durability in continuous marine cooling service, where the pump circulates raw water or coolant through the engine to keep operating temperatures in check.\u003c\/p\u003e\u003cp\u003eThis water pump directly replaces OEM circulating water pumps 3854017 and 3858340, so it is a straightforward swap for engines originally fitted with those pumps. It ships complete with mounting gasket 18-0327, so there is no need to source a separate gasket for the install. Sierra engineers its water pumps to meet or exceed the performance of the original equipment part it replaces, making the 18-3593 a reliable choice for routine maintenance or emergency replacement on applicable 3.0L and GM 4 and 6 cylinder marine engines.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-3593\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Circulating Water Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation:\u003c\/strong\u003e Bi-Directional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e 3.0L 4 cyl.
