Daimler/Jag windscreen washer reservoir - mikelong
The windscreen washer reservoir on my Daimler Six (1995) has obviously got a split in it. Is this component easy to replace? Any help would be appreciated

Rather than replace, assuming it is made of a type of rigid or semi-rigid plastic I've repaired splits in a couple of these by drying out the reservoir and applying a skim of Araldite so the epoxy is pushed through the split. You can smooth off the outside before it dries to give a neat appearance. Not knowing you specific car they are usually held on with a bolt or two and hook arrangement to the inner wing. I assume yours is a bottle visiable in the engine bay rather than hidden in the depths of the wing?

A much easier repair is to insert a reasonably thick polythene bag inside the split bottle (done that as a former Aberdonian)
