No, that external tank was a feature of the FE engine platform and was designed to be an extension of the radiator and a place to add coolant. Yours was likely added to help it look more CSX-original. Is it needed? It is if its the only place you can put a radiator cap. You have it installed, its functional, it looks cool and I doubt it has anything to do with your problem. But if you are bent on catching the overflow, then you are also going to have to add a recovery system if you don't like it draining out on the ground and having to constantly refill it. But I would suggest you solve the overheating issue first and then decide about the recovery system. If you can make your system stop overheating, it won't boil over and you won't need a recovery system.

This is provided that you think that the coolant loss you are seeing is just the boil over and not a leak elsewhere.
