Double C Service Center in Seymour, TX has the answers you need to become more in-tune with your diesel truck and engine. 

One of our vehicles lost a timing belt between Benjamin and Guthrie, TX. Middle of nowhere. While my son waited on a tow truck with his car, some quick research turned up Double C in Seymour. We had the tow truck take him thereafter the shop had closed one evening, I met them there after driving from DFW, and we left a note and the key in their mailbox. I spoke with Randy at Double C the following day and based on our first conversation, felt confident the vehicle was in good hands. What he was describing matched with my understanding of the repair. We picked it up today after a few weeks. The shop is closed on Saturday, but Randy met us on his off day since we had to drive 2 hours to get there. The cost was about $600 less than I expected and was done right the first time. Kudos to Randy and Double C for a great job. It can be unnerving dealing with an out of town shop you might not know, but Randy will take care of you. - 5 Star Google Review from Cam Reinhart
