Dilute the simple green 2:1 with water.
I always wash engines cold, even better if they sat over night.
I cover the alt, pcm and icm with plastic bread bags.
Soak everything with SG 2:1 and wait 20 minutes......move on to the wheels and tires
I then use a long cylindrical bristle brush to scrub everything down.
Rinse and repeat.
once its dry I dress hoses and plastic with Armourall tire foam.

And yes I'm long over due
