I'm surprised noone has opened to this poor fella of the famous and fatal failure with these 2.7 engines, smh. If only you knew better you wouldn't have bought the car, the person who sold it to you must be happy to have gotten rid of that headache. You would've ran as far as you could when he told you about existing probelm with the car. The water pump on these 2.7's fail often, did the seller tell You when it was last serviced and how often? And what was changed? You should always ask these questions when buying used cars. Your problem sounds similar to how mine started, mine ran w/o problems the 1st few days to weeks when I got it, till it started smoking from under the hood. Is your coolant over heating? Is your coolant reservoir bubbling out coolant? If so you might have sludge situation going on buddy. You should Always post Pictures/Vid of your situation it helps alot to see what's going on so you can get better advise/help.
