Is this an expansion tank for coolant

Is this an expansion tank for coolant?

  • yes :)

  • Ok what level of antifreeze should be in it as it looks empty but when i took radiator cap off fluid is up to the top?

  • The radiator cap it should be full. The expansion tank by its very nature, needs to give a bit and take a bit of coolant , so should be about half full. There should be a level marker on the tank somewhere.

  • Can't really see anything need to take fairing off :(

  • You can roughly tell just by looking through the filler to see if its half full. Its not crucial to be spot on, near enough is good enough, in this instance :)

  • Just took that side off looks 2cm below low

  • Filled up. Thanks for info Colin Webb
