Hello,
No, you should be able to replace the heater hoses from the engine compartment. Just remove the hose clamps and the heater hose and replace with replacement hose and clamps. I would recommend replacing the OEM clip style hose clamps with worm gear type hose clamps which are available at any auto or hardware store.
