You have to replace the entire assembly.
For the manifold see link below for detailed info on the class action settlement and detailed DIY instructions... http://www.autoclinix.com/Manifold.htm Is the intake cracked? Is it a 4.6L? If so, a recent class action settlement extends the warranty, on the intake, to 70,000 miles. Don't replace with OEM manifold.
No, not for the hose but, I have seen the metal bypass tube that the hose connects to, rust out and cause a coolant leak out the back of the engine. The intake manifold would have to be removed to replace that metal tube.
take it to the dealer
