It's the 2.5 liter 5 cylinder engine (wasn't an option on my phone) I've had my car since early October 2015 and I have had to put more antifreeze in it 4 times. It's not a fast leak, it's slow. But I can't pinpoint where it's coming from.

OEM water cooler has a plastic impeller which invariably will break and shard in the housing. You must replace this with an aftermarket water pump with a metal impeller. While you're in there change your timing and serpentine belts, cause it's a pain taking all that out.
