3.5 ecoboost suck and Jenkins & wynn ford dealer in clarksville suck even more. 30k miles ago I paid them to replace the timing crap along with the water pump($3,500). fast forward to now, water pump has failed and they want to charge me $2k to replace it....again. Not to mention, i've bought a $70k truck from them after the first replacement. I'm out, thats my last Ford.
