take it easy and slow. none of the hoses carry oil. un do each clamp as you see it, then replace the cooler doing up each clamp remembering which one you took off last, then working back. from memory, i unbolted it from the bracket, then manifold, then
bov and wriggled it around to get to the back of the cooler. thats about the only advice. if you dont feel comfortable nor confident, get someone who knows it back to front to do it. im sure it wouldnt cost much if you wanted piece of mind
