I did it on a T5 a couple of years back, not too much of a drama although there are a couple of bolts that are difficult to get to. Be aware that you will have extra radiators mounted in front of the coolant one for air-con, power steering (just a tube) and intercooler.
A second pair of hands are useful to handle the front bumper assembly when it's loose as it's a bit wide and bulky but not heavy. Don't forget to disconnect front parking sensors if you have them.

Lots of words about special tools but I never needed any - however the diagrams are helpful.
