You can get foaming degreaser at an autoparts store. It comes in an aerosol can like carpet cleaner.

Cover your alternator and cabin air intake (left side of windshield tray)
rinse everything lightly with the hose
spray everything with degreaser
let it set for 2 or 3 minutes
agitate lightly with a brush
rinse off
blow dry with air compressor or wide dry
start engine and leave it running for half an hour to dry everything

You'll be amazed how easy it is and how much better your engine compartment looks. Its terrifying the first time you clean an engine bay, but on a modern car like this its really hard to mess anything up. I wouldn't touch an older car with carborators and and a distributor cap though.
