Aircon condenser replacement

[Buki]

Hi all,
 
1.6 Blue HDI 2016,

There is a gas leak from the condenser, I can see an oil stain on it.

My question is - to remove the condenser, it is enough to unscrew the two upper mounts ant tilt the radiator toward the engine, or it will not give enough space and I have to drain the cooling system and remove the radiator? 

Thanks...
