Easy to change if you have a pair of axle stands or ramps, a good piece of wood and a trolley jack.
Raise the car onto the ramps or axle stands.
Release but DO NOT remove existing mount bolts
Carefully place wood on trolley jack
Raise Jack onto sump, with the good piece of wood between jack and sump, (yes I know this is dodgy, but if you are VERY CAREFUL and don't take too long it'll be ok. Did my XC 302 this way.) And then lift the engine slightly to release the cross member bolts.
Remove ONE engine mount, and replace it with the new one, then repeat for the other side. Don't tighten the bolts fully yet.
Lower jack out of the way and tighten the bolts completely.
Lower the car and your done!!!!!
I must reinforce, use a good piece of wood, and don't take too long with the jack holding up the engine
