I recently purchased an 07 F250 (104,000 miles) and within a few days of driving it it started overheating. Took it to the dealership and they replaced the EGR Valve claiming to fix the problem. I then took it to a diesel tech to have him look it over to make sure there were no other problems and he said everything checked out. I bought the truck in Texas (where I'm from) and started driving it to PA (where I work) broke down in Kentucky (overheated, white smoke, lack of power, losing coolant). Had it towed to the nearest Ford Service Center and they replace the EGR Valve, EGR Cooler, and Oil Cooler. It has been running great since, however I'm still paranoid that the problems are just looming waiting to get me again. I hear of everyone talking about getting an EGR Delete kit, but I feel obligated to keep mine on since I just spent 2700 getting it all fixed. I know we can't predict the future, but are there any problems I can expect to run into in the near future? Is there anything I can do to prevent further problems without an EGR Delete Kit? I use my truck for work to haul my camper and tools around with me everywhere. Without it I'm out of a job. I love my truck and I just want to make sure I treat it right so it will treat me right. Any advice would be greatly appreciated. Thanks in advance!
