I bought this edge with a water pump failed at 135k miles. I was going to fix it but I checked on car-part and the motors with oil cooler are around $650 for a low mile motor under 45k miles. I can buy a motor without the oil cooler for even less. $300-400 range. I have also read that the 2007-2008 motors when the water pump fails it puts coolant into the oil like mine did. Anyways After 2009 they have the 3.5L with a 3 bolt oil cooler. Would that work? Let me know your thoughts. And thanks in advance for the help.
