I need to get rid of this fitment and put a hose clip onto the coolant pipe from the turbo...

Now the trouble I have is I cant get a spanner in to remove the hose from the turbo end....

Now here comes my stupid question.....

Can you take any of the bolts off on the right and take it off the non polished housing so I can get the spanner on it ? Or will this affect the turbo at all ?
Cheers
