We consider various problems regarding roots and coincidence points for maps into the Klein bottle K . The root problem where the target is K and the domain is a compact surface with non-positive Euler characteristic is studied. Results similar to those when the target is the torus are obtained. The Wecken property for coincidences from K to K is established, and we also obtain the following 1-parameter result. Families f n , g : K → K which are coincidence free but any homotopy between f n and f m , n ≠ m , creates a coincidence with g . This is done for any pair of maps such that the Nielsen coincidence number is zero. Finally, we exhibit one such family where g is the constant map and if we allow for homotopies of g , then we can find a coincidence free pair of homotopies.
