85 300SD Turbo Cooling sys hose replacement

It appears that to replace the cooling hose
that is located on the engine head next to the oil filter housing is routed to the firewall. And to replace it will take removing the wiper arms and the air screen to access the nuts in removing the bolts on the ABS cmputer housing which will allow then access to the two hoses that must be removed. Whew! My MB manual says to refer to task 83-0140 for air screen removal, HAH! on me. The manual goes from tasks 82-xxx to 88-xxx! S-o-o-o HOW does one go about replacing the hose?? The hose is cracked and the fabric is exposed and do not trust it for long distance driving. After researching this website I feel confident that this is the place to ask for help! thanks bunch folks for your help. LH
