As usual Acme did a great job. I had a very small coolant leak in my F250 Deisel. Just a very small drip from time to time, but when I towed it was really bad. I could stop and check to see where it was leakiing, but couldn't find it. I took a 4 hr trip, when I refilled it took 72 ounces, but couldn't find it. Took it to Acme and as usual they didn't stop until they found it and made the repair.
