The Diesel Doctor

I bought a high mileage diesel truck (my first diesel) from an out of state dealer… «as is». That tells you everything you need to know! ;) So, what I did not know before, I am learning now… and one of those things is that knowing about gas engines is about as useful to diesels as experience in fast food is to fine dining! So, with that said, I looked online to find a diesel shop with good reviews to deal with the «issues» my new POS came with! The review Mark W. left did give me some second thoughts, but the other reviews won me over… and I am glad they did! Jesse and his crew did an excellent job, fast and for a very reasonable cost. My repairs would have broken the bank had they not worked with me on finding good used fuel injectors and in repairing (rather than replacing) my faulty Injector wiring harness! (saving me around $ 600!) Needless to say, they will be getting my business the next time something I can’t fix fails!

We have a fleet of diesel tow trucks here in La Mesa that is always on the road. Diesel Doctor has worked on these trucks for a while now and provides great work, quality pricing with fast service. He understands that our fleet can’t be down for long periods of times and keeps us on the road.
When we decided to change from Bob Stall Chevrolet to Diesel Doctor it was because Bob Stall held our truck for five days just to change out one of our batteries. We started looking around at diesel shops, but Diesel Doctor was the only one with good reviews and good reference from people we know. After talking to Jess we knew right away he was very knowledgeable on diesels.
Diesel Doctors have done large jobs on our trucks and none of them have stayed in his shop for more than two days. In the business we’re in if the truck is not running then we’re not making money and he understands that completely. My drivers can take their trucks by his shop if the check engine light comes on and then we will know on the spot what is wrong with the trucks.
I would recommend Diesel Doctor to any company with a fleet of diesels or someone with a personal diesel vehicle. They do great work and will stand behind anything they do on your vehicle. They are also great to work with and don’t mind explaining anything you don’t understand.

Excellent Diesel Shop. How rare it is, when an auto shop says you don’t need expensive repair, you have authorized. They saved me a ton of money and were very helpful. Fast and accurate Diagnostics. Good people. Highly Recommend!

MY EXPERIENCE:
In January 2015 I took my truck to Diesel Doctor because it would not start. I spoke to the owner who goes by Jess. Jess told me that I needed glow plugs. I hired Diesel Doctor to install the glow plugs; it cost approximately $ 500.00 for parts and labor.
In May 2015 again my truck would not start. There are two more components that work with the glow plugs; a relay and a controller. I installed a relay and my truck still wouldn’t start so I took my truck back to Doctor Diesel and I stoke to Jess.
Jess convinced me to bring my truck back so I did. Jess told me that I need glow plugs again and he would warranty the glow plugs. Jess installed the glow plugs and he put in a controller.
Jess called me and told my bill was $ 540.00. Jess charged my $ 98.00 for the glow plugs which he told me he would not charge. Fortunately he removed that charge.
THIS IS WHERE HE RIPPED ME OFF: THE CONTROLLER COST $ 144.00 AT NAPA AUTO PARTS. JESS TOLD ME HE PAID $ 244.00; THAT’S A LIE. AUTOMOTIVE BUSSINESSES PAY LESS FOR PARTS NOT MORE. JESS CHARGED ME A $ 171.00 TO INSTALL THE CONTROLLER WHICH TAKES 15 TO 30 MINUTES TO INSTAL. I CALLED «MDS DIESEL SERVICES» IN EL CAJON AND THEY TOLD ME IT WOULD COST $ 42.00 TO INSTAL THE CONTROLLER BECAUSE IT WOULD TAKE A HALF HOUR. IF YOU WANT TO PAY EXORBITANT PRICES AND GET RIPPED OFF THEN GO TO «DIESEL DOCTOR.»

To state with the diesel doctors are great mechanics, honest and completely customer focused.
I took my ford truck in and it had a cracked head. This is a common problem with the 6.0 liter Ford engine. The diesel doctors advise me of what I needed to correct this problem with no pressure. I had a choice of getting it repaired back to factory original or repaired to prevent this from happening again. With that choice I was educated very patiently in the history f the engine and what the corrective parts would do. There was no pressure at all.
They were more than correct and their prices were more than fair. The additional recommended parts were very much needed and I don’t have to worry about my truck cracking ahead or overheating. The diesel doctors were more than courteous. They took the extra time to explain everything to me and seeing the engine was already ripped apart for the crackhead they adjusted the time for the additional work to be more than fair.
Jesse is a master of explanation and dealing with warranty companies. He was able to get affected parts replaced that have not failed yet but inevitably due the contamination from the cracked head. He spent the extra time with me and the warranty company to ensure all was correct.
I highly recommend them and their expertise. The diesel doctors now are my trusted go to mechanic for diesel and advice. I’ve used a lot of other mechanics but I’ve only used them once. The diesel doctors El Cajon is a trusted mechanic which I will use again and again.

There is no one I trust more than Jesse to work on my diesel Westfalia. Yeah there are a handful of shops that will work on old Volkswagen cars or that occasional work on diesel cars but Jess is the only one I’ve met that not only fixes my westy for a fair price but also takes the time to show me what he’s fixed/​replaced and anything else I should keep an eye on. He always goes above and beyond like bleeding out my clutch a little cuz it felt tight without charging me for it. Or making sure my wiper blades are okay just in case it rains on my way home. I’ve been turning to him for several years, he’s always so honest and I trust him so much that the trip from North County San Diego down to El Cajon is worth it every time for that peace of mind. The service is always fast even though they are busy most days (so call ahead!) and repairs are always reliable. I have even rung him up to ask him a quick question about how to fix something small and he’ll take the time to teach me how to do it myself. The whole gang is wonderful, it’s a very personal experience and that is what I love the most. I’m so grateful for everything they’ve done to help me. It’s pretty much guaranteed that you’ll never want to go to another mechanic after visiting the Diesel Doctor! Thanks so much guys!

What can say about this place… THE BEST!!! Unbelievable people with knowledge that exceeds any place I’ve ever taken my car to. They are friendly, nice, and get the work done fast!!! Take anything to them and they will get it fixed!

Let me start with saying Jesse and Albert at The Diesel Doctor’s are an Extremely Knowledgeable group of guys, and are great to do business with. There was absolutely NO BS at the Doc’s like you would get at other mechanics. They pretty much diagnosed my truck over the phone, once I gave them the symptoms, sure enough they hit it spot on, it was exactly what they suspected. How many Mechanics can do that or would do that? NONE… I’m definitely going to be a regular at the Diesel Doctors and I Highly recommend them for all Diesel issues. My 7.3 is running like a straight beast after it’s appointment with The Diesel Doctors.

I am a former mechanic and I am very picky about who works on my truck. At The Diesel Doctor it is always nice to talk to someone who doesn’t BS you. I feel there are honest and more so when they don’t know the answer to a problem they let you know and then find out the answer. I had an uncommon internal engine problem that they were able to diagnose correctly. The truck I have owned for many years is running the best it ever has. I live in Clairmont and consider it worth my wile to drive to El Cajohn to get my truck worked on by someone who I trust
