2005 is definately safe for Valeo and paint. 2004 is probably too, just check the rad, there is a sticker on it which says the make. Galvanisation late 03 and nano paint mid 2004
just bear in mind that will have the SBC brakes on it - removed in 2006 (I think). Also if a diesel make sure there is no DPF fitted (think it is too early for that).
IIRC they just switched the manufacturer of rads. Check it carefully, if a behr you are fine. If a valeo get a gycol test for the gearbox oil, then buy a behr rad. If test says gylcol in there walk on.
If you can get the VIN no someone here can find the build date and that will reveal all.
