Diesel trucks can be very confusing to say the least. At Thoroughbred Diesel we have built our name as a real diesel performance and repair shop that offers free advice for diesels. This Diesel University section is meant to be a useful resource guide for ALL diesel truck owners.   Click below to see:  FAQ's, product videos, Diesel U videos, Q&A replays, How To,  and DTC diagnostic trouble codes. We trust you will find this information helpful.
