Am buying a new tensioner tomorrow for replacement. Top hose is red hot, bottom hose is warm.
Took fan belt off and ran engine for a few secs and the noise is still present.
Waterpump, fan belt and timing belt were all replaced. Noise still present.
Someone suggested that the water pump could have been tightened too much and that is causing the loud squealing?
Car has not been driven in two weeks now. Am getting fitter walking is the good side of this yarn.
This morning I noticed a running leak coming from below the radiator, just a small distance from a red 'bleeder' knob...
A good puddle of water can be seen on the ground.
I'm disabled so cannot get under the car and depend on others doing work for me.
Would it be a split in the radiatior and thus having to buy a new one, or can this be easily repaired. Would radweld do the job?
Sorry for so many questions, but do appreciate the help on here 

Waterpump has 3 bolts through body into block (seals on large o-ring) so "overtightening" wouldn't cause pump to squeal.  If noise still present with aux belt off i would be concerned that noise due to cambelt tensioners - needs investigation!!

Aux belt tensioner held on by one 15mm nut at centre - 5 mins to undo, fit new tensioner and retighten nut!!

Would the timing belt have to be re-set or just remove one end of belt from the tensioner, remove the tensioner and then slip the belt onto the new tensioner...would that be ok or am I totally wrong?

we now have a maint guide for flushing matrix....check that section.

it also shows the guide on removing those connectors.

Thanks jimbob.
I've saved the photo of how to remove the connectors...and had a go at this myself, but they seem to be 'frozen stuck'...is there a special tool that makes the job easier? Also noticed on my hoses that the coloured ends of the hoses  (shown in your photo) are not on mine, possibly were broken off a long time ago.. Is there only one thing to squeeze in or two on each hose?

The timing belt tensioner was replaced and the banshee squealing has thankfully gone now.
Thank you to everyone for helping.
