Egr cooler question

Well, if it's an oilfield truck, it's been used and abused. I know cause I iuse to deliver to the well sites, and the roads are only drivable at about 10 miles per hour, even if you want to call them roads. Then sometimes we would sit for 2-3 days at a time waiting to unload{ lots of idling on the engine}. Then one day at the kW dealer in San antonio, met a wrecker guy, who was making a killing hauling all those trucks out of the oil patch. And yes he had a big ole smile on his face, and gave me his card. Lol
