I know I never disconnected anything on the V6 except for the trans cooler on facelift cars.My memory is a bit vague, but fairly certain it was a later car where the A/C lines came over the top of the rad, unlike most Omegas where they a re to the side of the rad. It was one of those moments the first time I saw it when you had to ask what GM designers were smoking, seeing as they had previously managed to do it perfectly well.
Its not a common setup, but I've seen it on more than 1 Omega.
As said, dead easy check for OP to make, as if it does, it makes the job more difficult if you want working A/C after.
