There is a U shaped coolant hose at the back of the engine RHS. Check it’s not rotting out on the metal where it comes out. Some do for some reason most are fine entire life of vehicle.
You have a busy day, from sounds of things you are due for your luck to change ;)
 
Sorry I only noticed thus post. I was checking periodically to see any response and just found it. The hose at the back I recently became aware of. I have bought new and will replace. Think it means I'll have to take off inlet manifold by looks of it. It wraps around the back of the engine. Anyway thanks for the advice
