Fitted coolant sensor 2 weeks ago and took opportunity to change all hose clips to Jubilee, only when dismantled was seepage seen, (mainly from smaller pipes) as heat evaporates lost fluid, no loss at all since.

Seems frequent stop start/ short trips and difference in expansion/contraction of different materials may be cause when cooling down.
