Is the A/C condenser attached to the rad'?
On the early models it isn't. So battery out [ to make some room], hoses off coolant drained of course, The whole shroud with the fans off [ fiddly a stat last bottom right screw is brail method only
], it you can - remove alternator to give you more space, remove the 2 top screws - lean it back slightly and lift it out.
Earlier models have a shorter radiator, '05 prob has the taller rad like the V6's.
