Im giving the folks at LCD 5 stars, having recently picked up an older 03 6.0, I wound up at LCD to get some work done. Through the conversation and other considerations I decided to do the stud/egr cooler work while addressing the original reason for the visit (several oil leaks, bad ICP, etc). There are some deltas in the labor that made it pretty cost effective. There were some concerns early on, with the pace of the work and communication, but Rob and Austin and the team listened to my feedback and made changes to keep me in the loop. I appreciated the corrective action and won't hold it against them in the review, but it should be mentioned if you share a similar experience. Just talk to em. That said, I will absolutely continue to work with LCD in the future for any work my truck needs. I have a 22yr old truck that run's stronger than I ever expected out of an old stock' 6.0 read more

I've been taking my truck to LCD for many years. They always do amazing work. They go above and beyond weather it's a service or a repair. They know what they are doing. I never hesitate to take my truck there. Thanks to Ross and the whole team. read more

Took my 7.3 here to perhaps change my abs sensors . Talked to the guy ross I believe and at first didn't even want to look at my truck because it had a tuner but idk what that has to do with abs . Anyway i dropped it off and the get a call saying its ready for pick up . I unfortunately couldn't make it and had my wife pick it up and no receipt or anything was given to her after we paid for them to "look at it" . I called and said what was wrong and they suggested me re doing my entire front end re done and was told it was going to be almost at 5 thousand dollar job including brakes and roders and ball joints . All i wanted was my abs sensors replaced and got my money wasted for them just to "look at it" and still walk out with the same issue i came in with . No help whatsoever, waste of time and money. Would never recommend anyone go here unless you want to give them an arm and a leg to fix your vehicle! read more

I brought My 2002 7.3 excursion to Ross. I had fuel in the cooling system due to injector cup failure. Ross was up front and honest with issues and the what my options were with detailed break downs of each with reasons for his recommendation based on our consultation of what this truck servers to my family. I had the pleasure of having Jacob as the lead mechanic for my truck since he was the 7.3 expert at the shop. My interaction with Jacob from a diesel truck enthusiast perspective (not a mechanic) and only in tune with the trucks I own. Jacob was respectful and very professional, as well were the other 2 mechanics that helped. Jacob was very knowledgeable and thorough. through the entire duration of the project both Ross and Jacob were diligent in updating me on progress and notifying with pitfalls for sourcing parts which led to the project going longer than they estimated and no fault to Ross or Jacob since its an older truck and parts are hard to find. Some parts they even had to learn to make. After the job was completed and they returned the truck back she sounded perfect and ran great and hopes that with good routine maintenance from this shop this truck will continue to serve my family for many years to come. I would profoundly like to thank Ross, Jacob and the rest of the team. They were great and I think they well understand what diesel trucks mean to their owners. The mechanics seem to take great pride in mastering their craft. It was evident that some of the parts that no are no longer available and they had to make took a lot more hours than what I was billed in the contracted work order day 1 and I'm convinced from my encounter with Jacob, he spent time at home off duty trying to solve my trucks problems. That is not a normal trait in this day and age. Mad Respect to Ross, Jacob and the Concord Left Coast Team. Thank you, Kyle read more

They kept me informed of what was happening with my truck, and worked to keep the price down for me. I've been taking my truck here for 20 years, and it's still running great!!! read more

Left Coast Diesel - Running great now! - Auto Repair Near Me - Concord, California

Like many others on here, I was in dire need of some help and I just happened to read some reviews that pointed me to Ross and his team. I had a really nasty exhaust leak on my 6.0, Ross was able to confirm there weren't any other (and more costly) issues at hand. If you're looking for a shop that knows their way around a 6.0 (or any other diesel), look no further than Left Coast Diesel. read more

Ross and Left Coast Diesel are the absolute best - the only shop that gets to touch my 04 Ram 3500. We travel full time and this truck is our tow vehicle, so it's critical that it's running well. Prices are fair but the work is top-notch excellent. Communication is always punctual and professional and timelines have always been delivered as promised. Several times I've been lucky enough to get same day service. I was having some strange symptoms, so I called Ross (after talking to several local shops in Vegas, where I was). Ross spent a few minutes on the phone with me and off to the parts store I went. 15 minutes later the truck was running like new. Ashamed to admit I neglected the fuel filter pretty badly.... If you read a negative review of this shop, I'd be suspicious of their understanding of auto repairs. This is not a non-profit; It's a business with a lot of specialty knowledge and they should be paid fairly for that. Now stop reading reviews and wasting time, and just call Ross. read more

Left Coast Diesel - Don't let your fuel filter get like this....oh the shame.... - Auto Repair Near Me - Concord, California

Left coast diesel was recommended by some of best mechanics in the area. They did not disappoint. I took my 06 f250 and got it completely bulletproofed. Ross' customer service and explanations made me feel really comfortable. They didn't try to up sale me on anything I didn't need. Their services came with an an amazing warranty. Best of all they gave me a stellar 5% off parts and 20% off labor for being a veteran! Highly recommend for all of your diesel truck needs. I will be taking it back for all of my services. Thanks again. read more

I am more of a review reader then a reviewer. However we really felt the need to write a review about Left Coast Diesel First of all my husband and I had a really hard time trying to find a reliable honest trust worthy diesel mechanic BINGO We have found our new mechanic left coast Diesel Ross and the rest of the mechanics took such great care of our truck they took care of us we always were informed of the steps they were taking we're always updated.

By far the best diesel shop in the ENTIRE BAY AREA. They take care of the whole fleet of our trucks and keep everything on the road . Thanks Left Coast !! read more

My truck was left with this shop (Rob). The odometer was broken. So he and his staff decided to operate my truck for their own personal use. Once the work was finally completed, the truck went into limp mode and the dome lights were ruined by his mechanic. I returned it. They tried to tell me it was in limp mode because I did not know how to operate my truck. Lol. Finally they said they would look it over. Then I get a call from them saying my truck has now been vandalized in their lot. Turns out they were using it again and damaged the vehicle. I learned this because I know someone connected to the business. Do not take your truck to these crooks! Left Coast diesel ownersp is not honest and their work is poor quality! read more

Best in the business at keeping my fleet going. Ross is super responsive and always gets the job done as fast as they can to keep my trucks on the road. It's super important for our trucks to be running as much as possible and Left Coast makes sure that can happen.

My new diesel shop! Wish I had picked Ross and the team sooner, instead of an other local shop. Dodge 03 2500 WD had fueling issues. Limped the truck in and they have been up front and clear about the issues found, their causes and gave options to fix and/or upgrade parts to ensure the best diesel truck possible. Left Coast went beyond just fixing and cared that the truck was better than when it came in. Again best shop I've used! read more

I come to Left Coast Diesel when my check engine lights come on for my 2014 and 2015 F250s. The shop manager is quick to run a diagnosis for me and advise me on what codes are triggering the lights. Usually it's a easy reset of the system or something that's covered under my Ford warranty that the dealer takes care of. They are always honest with me and I trust them. I use to have a non bullet proofed 6.0 and was here often. They did excellent work on that truck. Read prior reviews. All in all great shop with knowledgeable staff. read more

Ross and the new team at left coast are absolutely top notch. I've been bringing my truck to another local diesel shop and had some issues with them last time. So I got referred to this shop. I called and talked to Ross the owner and scheduled to bring the truck in. Ross knee exactly what was wrong and reccomended what needed to be done. While the truck was in the shop he followed up with me everyday till it was done "covid parts delay" and that was huge relief. When I got the bill it was less than originally quoted. Let me say that my experience was Amesome and i highly reccomend you gives these guys a shot if you want it done right. read more

Left Coast Diesel - Truck is all cleaned and back at home. - Auto Repair Near Me - Concord, California

I took my truck to left coast diesel to do a once over and general health check on my 2006 dodge 3500 mega cab 6speed manual. The my went through it and found a few issues. One being my ball joints were shot. We discussed a few options and landed on factory style replacement. They see these trucks day in and out so they see the issues that I may sometime not see. They also ordered me up an Edge CTS2 monitor system so I can track EGT and other critical engine performance. Really happy with the customer service and how up front and honest they were with not wasting money on aftermarket parts that won't improve the handling and reliability. Thanks guys for taking care of me!! read more

Called Ross seeking advice and council on my 04 Excursion w/6.0 Powerstroke. Ross was able to troubleshoot my problem, fix it, and get it back to me within 24 hours. Ross knows the 6.0 and took the time to explain what he did. Ross went above and beyond and is my new 6.0 mechanic. read more

I recently bought a 2001 ram 2500 4x4 that needed a bunch of things sorted out to get it running correctly. I did some research and spoke with friends and all roads pointed to LCD as the place that knows these trucks best. First order of business was having them install a FASS lift pump, which they did a really good job on. They mounted it well above the bottom of the frame rail so it will be protected in-off road situations. They also managed to source a really nice Fleece sending unit to work with the FASS, and at a great price. Next, the steering was extremely sloppy and they recommended we replace the track bar and several other connections in the steering linkage with Moog components, since they have a lifetime warranty and are greasable. I really like that they didn't try to upsell me on some of the fancier front end components available for these 2nd gens - you can go overboard pretty quickly and the overbuilt parts can put too much stress on the surrounding parts and things will break. The truck has very little play now and I couldn't be happier with how it steers and handles. After that they tackled a gear-hunting issue I was seeing from 3rd / 4th on the auto transmission. They found oil-saturated electrical components on the transmission during the service and were 100% confident it was causing the issue. Sure enough, after replacing those parts the shifting issue is completely resolved. After that, they fixed a small diesel leak near the injection pump and changed fluids in the diffs and transfer case. Now the truck runs like new and is ready for anything. Even though LCD is nowhere near where I live, I will not hesitate to take my truck back there for whatever it needs in the future. Many shops in the Bay Area claim they know how to service a cummins (or any other diesel), but after making several calls and speaking with many mechanics, I didn't get the feeling that everyone is as familiar with these trucks as they claim to be. But after 1 minute on the phone with Ross at I knew it was the right place. Thanks guys! read more

Great Work with Top Parts My truck needed new hubs, ball joints, shocks and an assortment of associated parts. They found all and reassembled on my timeline. Parts are top notch (Moog and Red Hat) and many have lifetime warranties. It's worth noting that they did not replace items that did not need replacing. Squeaks are gone. Truck runs smooth and solid. read more

I'm really happy Ross and the new team have made Left Coast Deisel a huge success. It's clear these guys have a lot of pride in their business, shop, reputation and quality of work. They have succeeded in taking this business from a worn out, tired side show to now the leader of the pack. I had several experiences during the previous ownership. It was the typical experience you would expect from a performance shop. You can't get anyone to answer the phone, only voicemail. You may or may not get a call back, if you do it's hours later. They tell you to drop your truck off then it sits there for days, a week or more with nothing being done to it. They tell you to pick up your truck, it's done only to show up to find out there are still several things that need to be completed and just bring it back next week. When you rely on your truck all day every day for work, this type of poor service doesn't work. My first experience with the new and improved crew was great. I called, Ross answered the phone, I told him what was going on with my truck. He asked me when it would be convenient to drop it off, we can look at it as soon as first thing tomorrow morning. I showed up at 7:15 as discussed. Ross was opening up the shop. He checked me in real quick and I was off. Ross called me at 11am letting me know what needed to be done, the parts he suggested, warrantee info (lifetime) and a cost. He told me I could pick up the truck the next morning. This job was a complete front end rebuild, pretty impressive. Bottom line is we are fortunate to have access to quality performance work, service and repairs. These guys appreciate their customers and it shows. Prices are very fair and service is second to none. I would confidently recommend Left Coast Deisel to my family, friends and acquaintances. No matter how good you are, you'll never be able to please everyone. The snowflakes (pretty obvious) leaving whinny reviews about cost and a Trump bracelet are always going to be on Yelp crying about their feelings being hurt over nothing. We live in America, we are ALL free to express ourselves wether it hurts someone's feelings or not. Suck it up. read more

Ross at left coast was awsome! Kept me up to date with my duramax getting injectors replaced. Great work and service and got me in the road just in time for a hunting trip! Thank yall much!!! read more

I bought a used truck about a year ago and I knew it had issues but have just been trying to chase them out on my own. First time I went to left coast was for a sensor issue that resolved quickly. Then had to go back for a pretty bad oil leak and fuel leak which they fixed ahead of schedule! My last problem started small but lead into a massive project with problems sourcing parts, but Ross and his guys got the job done as quickly as they could, and worked with me all they way through. I appreciate their knowledge and the job they did to get my truck back to me running and riding better then ever. I definitely recommend Left Coast Diesel to anyone looking for a diesel specific repair shop. read more

We have a 2004 F350 diesel and I came in to get an oil change and an honest opinion on the condition of my truck and we got more than that! Not only did Ross fix the issues we had, he also gave me advise on how to take care of my truck properly so I could keep it running good for as long as it can. He knows his stuff and I highly recommend Left Coast Diesel for all of your diesel needs! read more

Great shop Ross and team Are on it want for oil change in and out won't go anywhere else . Thanks again

First of all, whoever left the one star review is so far off base it's ridiculous! They must complain about everything in their life. Ross , who is the owner, is not only the most stand up , and honest guy you could ever meet, he is also very knowledgeable and will tell you the truth , even if you don't want to hear it, regarding your truck! They have taken care of our Diesel Truck since we got it, and we would not trust ANYONE ELSE , but Ross and Left Coast Diesel in Concord! We know when we leave it there, its in good hands and will get fixed correctly! These guys are the "BEST"!!!! You will never need to go anywhere else!!! - Wendy read more
