my upper radiator hose is being abraded by the cover shown in the picture (forgive me, i forget what this is). how difficult is it to remove, if it can be? and as a side note, how many steps need to be done in order to replace the upper hose as a PM service? can i just pull the clamps off, and deal with the loss of the coolant in the hose? after almost 10 years, the hose is still in remarkably good condition. but may as well...
