"Hi, My name is Jim Cannon. I am writing in reference to repair work done on my 2000 Cadillac Seville STS that Davis Auto Repair did for me. Before Dale repaired the engine on my 2000 Cadillac Seville STS, with the Northstar engine, it was overheating severely. I was told by a Cadillac repair shop that the head gasket was probably blown and would require extensive repairs costing several thousand dollars. I was also told that this was a common problem with the Northstar engines of this particular year.I found out about Davis Auto repair and I contacted Dale and he was very nice and told me what he had to offer to repair my Northstar Engine. I took my Cadillac to Dale’s Auto Repair Shop in Youngstown, Ohio and after only two days, Dale had all of the repairs finished on my car and I drove it over 100 miles home without any overheating problems at all. It has been over a year now, and the Engine still performs like new. I am very pleased with the repair that Davis Auto did to my Cadillac. I have since recommended his service yo many dealers and repair shops in my home area as well as many individuals and friends. If you have any questions or would like to speak to me personally, please feel free to contact me at 724 344 7178 or E-Mail me at

"Hello Dale (Cadillac Doctor),
In March 2011, our daughters 01 Cadillac Deville with only 40k miles began to run hot and overheat. We were shocked to hear from our local mechanic that the car needed the head gaskets and bolts replaced and the cost would EXCEED the value of the car! After searching both locally and online we were fortunate to find Dale Davis in Youngstown, Ohio (about 8 hour drive from us on Long Island). Dale removed the engine from the car, heads, accessories, intake, exhaust manifold and head bolts. Each head bolt was drilled out with a special drill and Time-Serts were installed with new head bolts. The engine was re-assembled with all new gaskets, anti-freeze, spark plugs, oil change, water pump and thermostat. Dale found that we had a cracked motor mount and replaced that for us too. As the repair was in progress, Dale and Dale Jr. took 13 photos and e-mailed them to us. Dale had the car completely repaired in only 1 week! He also completed the entire repair with parts for $1550 and guarantee's his work for 1 year, unlimited mileage. This is a very fair price considering the complexity and amount of hours required to complete a job like this. Our daughter now has 65k miles on the car without any overheating problems at all. The car simply runs flawless. Don't give up on your Cadillac Northstar if it starts overheating. Get it to Dale Davis in Youngstown, Ohio. " I'm glad I did."

This is a letter to just thank you so much for bringing back life into my fathers Cadillac. As we talked about, My Father passed away 2 years ago and he left me his beloved Cadillac. The car developed the dreaded head gasket problem 4 years ago. For the first 2 years we talked to everyone we could about where to have this repaired. All the local Mechanics either did not have the skills to repair this car or was afraid of touching it. Even the Cadillac Dealer ships for about 250 miles from Tulsa would not touch it, they tell us there tech's were not trained to repair these head gasket problems.

The car has sat in my Garage now for the past 2 years and has not moved. I was debating just having a new engine put in it, but the dealership quoted me a price of $11,000.00 then they told me they had heard of a man in Ohio that repairs these, So after about 2 weeks I found you, At first I thought when you told me you only charged $1500.00 for the repair that surely you couldn't know what you were doing, but after we talked a few times, I felt comfortable allowing you to repair my fathers beloved Cadillac. I am so Glad I did, You even helped me to find a good deal getting the car shipped to you. After the repair, in just 3 days, you came to pick me up at the airport and I could not believe how well the car ran, It ran like a brand new car all the way back to Tulsa, and now, six months later it still runs like a new one.

Dale, words cannot explain how thankful I am to you for bringing new life into my fathers car, I just wish we had heard of you before he passed away. I am sure he is looking down and smiling. I am forever in your debt."
     Sincerely, Paul Rudderford Tulsa OK.

"Davis Auto Repair replaced the head gaskets on my 2002 Cadillac Deville with the 4.7 Nothstar V8 engine. The repair included installation of the Timesert kit and replacement of the water pump and all incidental gaskets, oil and coolant. The work was done in June 2011 and since have had no issued with the vehicle. I highly recommend Dale and his people. Their service eas as stated, on budget and on time."

"The repair on my 2003 Cadillac Deville was exceptional. The vehicle was overheating and I was quoted by other garages for repairs ranging from $2500.00 to $2800.00 dollars for replacement of the cylinder head studs. Dale repaired it for a fraction of the cost using the latest and best products on the market. I have since traded the vehicle, but not without putting over 5000 trouble free miles on the repair."

My name is Paul. I called the Cadillac Doctor from Little Rock Ark. He answered all my questions and I felt secure with having my car delivered to him there in Youngstown Ohio, He also pointed me in the right direction about finding the right people to ship the car there. He repaired the car above my expectations, I could not be happier. I bought this car at a auction, and did not know it was over heating. I called every shop and dealership with in 200 miles of here, everyone of them telling me, sorry, cannot help you, we wont touch those engines. I did not know what I was going to do, but after a brief search on Google, I found Dale at Davis Auto repair, The Cadillac Doctor. I gave him a call, with in a week he had my car and it was repaired with in another week. I flew into Pittsburgh and he picked me up, and I drove the car home, I am a salesman and spend a lot of time on the road, so far I have racked up 18000 miles and have not had the first problem, thanks Dale.          Paul, Little rock Ark.


Dale, I want to thank you and your staff for the great repair on my 02 Cadillac Deville. After looking for 2 years I had just about given up on ever finding anyone that had the skills required to repair the ol' girl. I just love this car and it was well worth the 8 hour drive to come get her. Thanks for taking care of the shipping on this car as well. You are more than welcome to ad this to your web site. You and your crew did a outstanding job, To be honest with you I did not know what to expect, I was told to be careful sending a complete stranger that much money in the mail with out first meeting you, but after talking to you a few times I picked up that you were a honest and trusting person. I would recomend you to anyone. Again, Thanks, I have put a few thousand miles on the Ol' girl since the repair and all is good. You and your staff were very professional. You have made a friend, customer for life. Sincerly, Bill Dawson, Chiago Ill.

Dear Cadillac Doctor,
When it came to fixing my Northstar on my S and S Presidential Cadillac limo all of the local shops wanted to replace my engine for about 4500.00. Plus. I did some research and found you and the first thing you said was "Why replace it, I can fix it for about 1600." The I knew I had found my man. Wonderful job, great price, and great turn around.
Great communication.You are the man.

Bought a '99 cadillac a couple of months ago, only to learn it had an overheating problem, which was a problem with the head gasket. I found Cadillac Doctor on the internet, waited my turn, and today passed the E-check which it had failed three other times. The car runs great and just wanted to say "Thanks" to Dale and those that had a hand in getting my car road worthy. I highly recommend the workmanship and the price. So glad I allowed myself to spend hard earned money to fix a problem that wasn't made clear to me when I bought the vehicle. Thanks Cadillac Doctor.


Hello Dale,

     Just wanted to send along a "hello" and let you know that my "Davis Northstar" is running beautifully ........ couldn't be better.  Am very pleased with it's performance.  With the new "muscle" the old Caddy has become a Great car, due to the personal interest you took in my situation.  Thank you again for the "extra mile".  Hope things are going well with you and that your health has returned.  Please say hello to your wife and son for me.  If I ever get to Youngstown again, I will surely look you up.

Your friend,

Seth L. Rogers

“Dale and his team did an excellent job repairing my wife’s 99 Cadillac Deville.  My wife took the car for a weekend trip to Louisville but the engine overheated.  I took the car to a local mechanic, they conducted an exhaust gas emission test and concluded that the engine was overheating because exhaust gases were getting into the coolant and heating it up.  They did not detect any loss of coolant.  They wanted to install a rebuilt engine from Jasper Engines and Transmissions for a cost that exceeded the value of the car.  When I called Dale and explained what was wrong with the car, he assured me that he and his team could make the engine “as good as new”.  I’m totally pleased with the performance of the engine and highly recommend Dale and his team if you need this work on your Northstar engine.  Feel free to contact me at (812) 550-0069 or brian.moody@dsm.com if you have any questions.  Brian Moody, Indiana, September 2014”

Hello Dale,

I doubt you remember me but last year you repaired the head gasket problem I was having with my 01 Deville.  It's been over a year now
and the engine is running just fine.  No overheating problems at all.  Just thought I would write and say "Thanks" again for the good work.
Before talking with you, every repair shop I took the car to told me the only resolve was a new engine and the cost would be about $6,000.00.

I've put about 12,000 miles on the engine since you did the repair work with no further problems with overheating.

Best regards,

Wanted to take this opportunity to express my gratitude for your services that you provided for our 99 Cadillac Deville this past December. Searching the web for a repair facility usually leaves a person unsure as to where to go and whom to trust. Fortunately, I found you!

Since we were already going to drive to Cleveland for Christmas, I figured I would give you a call and see if you could fix our Cadillac head leak while we were there. I knew with the cold temps that it would probably make it there as long as we stopped to check on the coolant level now an then.

After talking to you on the phone it was obvious you were the man for the job, and that gave me a better sense of security bringing it to you. Trust goes both ways, and that is obvious when you allowed me to drop off the car at your home on a Sunday morning. I don’t know of any other business that would offer that option, especially since we had never even met. With this sense of trust, we decided last minute to go with a rebuilt in lieu of the repair. You stated that you didn’t have any rebuilds’ available, but that you would rebuild mine. I was surprised at this offer, especially due to the time constraints that we had to depart back to St.Louis the following weekend, and particularly because this was the week of Christmas. You stated not to worry.

You and your technicians worked the week of Christmas (which included some overtime) to get my engine not only repaired, but rebuilt. I seriously don’t know how to say thank you enough for the effort that was put forth.

The car is running great, and my daughter has taken it to Arizona for a temporary job. She will be returning and then using it for Graduate school. The car has been in the family since new, and we are glad it was repaired and not sent to the junkyard.

From the little you have shared with me about your history, somebody needs to make a movie about your past. I would definitely pay to see that story on the big screen.

I will be calling you in the future for all of my Cadillac questions!!

Thanks again – Sal in St.Louis 3-24-2014.
