Radiator (and all corners) was hot. The pipes in the corners were not quite as hot as the fins on the side of the engine, but I couldn't keep my hands on them for long.
The water pump itself (and hoses going to it) were hot. When I took the cap off the radiator (turned engine off and left a few mins) I got a good hiss for the first part of opening. I started the engine with the cap off and could immediately see loads of bubbles in the radiator. ...
Did you actually see bubbles or was the cooling fluid just agitated? If bubbles, that is not good news as it points to a head gasket.

Afraid this is another bad sign.
