Egr cooler question

[Paracefan]

Thanks for all the input, I really appreciate it. I gave the truck a once over last week, I'm sure there will be some surprises with the suspension but my main concern is the motor. Like I said, he added 3 gallons of coolant and tells me there's no external leak. It was at the rush peterbuilt in San Antonio and when I spoke to the service desk there where thinking it was the egr cooler. 4 hours later the salesman says it was just clamps. Now for a week I'm reading up on these egr motors and 1, not sure I believe the "just clamps" story and 2, I don't know if I want to go down this road at all. My C-15 acert is a headache anymore but still might be better than this. I have a flight reservation booked for April 7th, I have until then to decide. I do have a refundable deposit on the truck.
