OEM Yamaha 'O' rings used to seal the coolant gallery water pipe.

On 2001-2005 models three 'O'rings are used, one  large to seal joint to Thermostat and two small to seal pipe to  cylinder head. 2006-2020 just require two small'o' rings to join 'H' pipe to cylinder head.

Always use  new O rings and make sure the mating surfaces are scrupeously clean when installing or it will leak and cause you another stripdown!
