Will go back here every time. They take care of their customers. Can always answer any questions and very seldom do we have to bring it back a second trip to get it right. We have a fleet of trucks. And no one else touches them but Coy's more

Great service and excellent knowledge!!!!! 4/20/2017

Coy's has always gone above and beyond with the service on my vehicles! They have performed all the work on my last 3 vehicles and will continue to get my business with my new vehicle. I had an issue with my 06 Duramax no one could figure it out and literally I was there 10 minutes explained it to Coy and he had already knew what the problem was and was able to get it taken care of!! more

Typical Louisiana business that I have experience to me. 7/7/2016

Had work down on my truck and after the truck started throwing EGR codes. I called to get my truck in after spending close to 2000.00 friday , before a big weekend. Thank you very much! I fixed it myself. Have a nice day. more

Using Coy's from 2008 to now. 7/2/2016

They do a great job on my 2006 F250. Coy's is the only place that has worked on my truck. more

Experienced 6/15/2016

Great diagnostic more

Unsure about need for work performed. 6/10/2016

I am concerned that I had $1,600 dollars worth of work done for no reason and another $500 left to do because of a misdiagnosis of a problem. My truck had an intermittent spin/no start issue. Your shop diagnosed it as a faulty pcm. Then, due to an egr delete and me not having the old tuner (I bought the truck used), I have been stuck with a check engine light. Well, the pcm replacement did not solve this issue. After bringing it back in, it was determined that the cam position sensor was bad (a $70 part) and was changed without labor expense. When talking with your mechanic, he told me that he diagnosed the pcm because the truck would not turn over and the trailer brake control was flashing when he attempted to do so. My truck was not and never did do that. Also, I was told it was diagnosed as such because of codes that were present which directed it as faulty. Yet, the mechanic said it was because it showed a physical sign; not a "code". Now, I still need a $500 programmer on top of having spent $1,600 that o do not believe was necessary. I would like a return call from Coy to discuss this further. more

Friendly 6/10/2016

Great Customer Service & Quality Work more

Quick, knowledgeable and professional service. 6/6/2016

Had bullet proofing completed on my 07 Ford F-250 Harley Davidson in October 2015. Excellent work and reliable performance as a result. The 6.0 performs like a beast now! Breathes easy and delivers loads of torque. more

    I received automotive training at the Universal Technical Institute in Houston, Texas. After graduating I continued my education through the Ford Fact program. This allowed me to begin my career specializing in Diesel repair.

    Coy's Diesel was started in my spare time while I was working as a certified technician in a local dealership. After being voted Employee of the year in 2008, I wanted to provide more services and I would need my own shop so I went out on my own in 2009. I hired Terry Seal who trained me when I got my start in the dealership and now we work side by side in helping customers and problem solving daily. In November of 2014 we moved into our new state of art facility off Airline Hwy and we now have the capability to provide service on all light and medium trucks, with certified technicians that have the experience to fix some of the hardest problems.
