Mr Gasket Swivel Water Neck

Part # 2670

Note: Fits 1997-'09 GM LS Engines. 1997-'03 & 2009 engines must use the 2004-'08 Thermostat (we suggest part number 6367 160 degree, or 6368 180 degree thermostats).

***Make sure the small air bleed port (located at the tab in the gasket) on the thermostat is facing upward. If necessary, the small tab can be cut off the gasket and thermostat rotated to move this air bleed to the top (this will allow any trapped air to escape). This will only be necessary when the swivel is moved a significant amount vs. the stock water neck.***

Great for engine conversion applications where engine/radiator inlet and outlet ports may be in different locations versus original equipment.
