Our heavy duty services include:
Cylinder Block
A cylinder block is the powerhouse for the motor vehicle. The solid cast car part houses the cylinders and their components (gaskets, valves, and seals) inside a lubricated and cooled crankcase. Since it is one of the most important parts of your car, the block is designed to be extremely strong and sturdy. Although strong and sturdy, the block is susceptible to failure resulting in a vehicle that won't start. Cracked blocks, porous blocks, core plug, or freeze plug failure are some of the problems facing cylinder blocks. Call 765-674-4444 to talk to the mechanics of Corey's Automotive Repair & Service about your cylinder block problems.
Cylinder Head
A cylinder head is the closed end of a cylinder (located in a car's engine block). It sits above the cylinder block, closing the top of the cylinder and forming the combustion chamber. The cylinder head coordinates airflow in and out of the engine. Since the cylinder head's chief function is to seal the cylinders properly, insufficient compression results in the car being difficult to drive. To have your cylinder head checked and repaired, talk to Corey's Automotive Repair & Service's cylinder head repair and reconditioning specialists today.
Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:
- Changing the oil & filter
- Changing the air filter
- Changing the fuel filter
- Bleeding the fuel system
- Draining the water separators
- Refilling the urea injection system
You can count on the experts at Corey's Automotive Repair & Service to help your diesel engine last a long time.
Engine Maintenance
Any car part manufacturer will tell you that preventive maintenance is critical to the part's lifespan. Like other auto parts, car engines aren't built to last forever. However, you can increase the engine's lifespan by performing regular preventive maintenance. The easiest way to maintain peak performance and fuel economy is to provide regular engine maintenance for your vehicle. To have your engine maintained by experts, visit Corey's Automotive Repair & Service.

Engine Replacement
The engine converts energy into useful mechanical motion. This amazing machine is what keeps your vehicle moving. Although generally reliable, a car engine is susceptible to damage and breakdown. When this happens, do not sit and stress over it. Take action. Take the vehicle to a mechanic for an engine replacement. Bring it to Corey's Automotive Repair & Service. Visit us at 224 S Baldwin Ave for quality engine replacement services.
Timing Belt
A timing belt is a part of your car's internal combustion engine. The belt synchronizes the camshaft and the crankshaft rotation so that the engine valves open and close at the correct timings. Also, the belt prevents the piston from striking the valves in an interference engine. A timing belt is a rubber belt that usually features teeth on the inside surface, while a timing chain is a metal roller chain. Most cars we drive now have timing belts instead of timing chains and gears. Although different manufacturers have their recommended mileage, you need to have your car's timing belt checked regularly. To have it checked by experts, contact Corey's Automotive Repair & Service today.
Transmission Flush
Although most manufacturers recommend a transmission flush every 30,000 miles or every two years, some symptoms may indicate that you need a transmission flush sooner. Some of the symptoms that indicate that your car needs a transmission flush sooner are: transmission grinding or strange noises, problems shifting gears, slipping gears, surging of the car, and delay in vehicle movement. Flushing the used fluid from the transmission washes away tiny particles of dirt, clutch material, and metal shavings. For all your transmission flush needs, call 765-674-4444 or visit Corey's Automotive Repair & Service today - we are transmission experts.
Transmission Maintenance
Any car part manufacturer will tell you that preventive maintenance is critical to the part's lifespan. Like other auto parts, car transmissions aren't built to last forever. However, you can increase the transmission's lifespan by performing regular preventive maintenance. The easiest way to maintain peak performance and fuel economy is to provide regular transmission maintenance for your vehicle.

Transmission Replacement
In motor vehicles, the transmission usually refers to the gear box, which uses gears and gear trains to transmit speed and torque from a rotating power source to another device. You can have your car's transmission replaced with a new, rebuilt, remanufactured, repaired or used transmission. For more information contact Corey's Automotive Repair & Service in Marion, IN.

I'm from out of town and was here in Marion for work when I started experiencing engine issues. Not knowing anything about the town I went to Google to look up repair shops. I looked at the stars and read the reviews and Corey's seemed to me to be the most honest. I was in the hospital for a few days and the car was dead in the emergency room parking lot when I contacted Corey. When I got out of the hospital, Corey went the extra mile to come to the hotel to get the key and he towed the car to his shop. We discussed a couple possible problems and he went through them. Unfortunately it was bigger than what I thought it would be, but he was always upfront and honest. I can see why his shop is hopping.

My wife was in Marion going to set up a vender booth at a craft fair when our truck broke down. I pulled google to find the closest shop that was going to be open (Saturday) found C.A.R.S. Looking at the reviews really quick and read the business details and made my decision pretty quickly to have our truck towed there. I called Cory we talked for a bit being a veteran owned made me feel even more comfortable being a vet myself. He had our truck back to us Monday afternoon being a pretty simple fix didn't take long to find the problem and didn't gouge us for it. Cory was honestly hands down best mechanic I've ever dealt with, quick and effective repair and didn't charge an arm and leg and our first born Lol. Definitely recommend!

Very reliable and honest mechanic. When my daughter's engine needed to be replaced, I brought her vehicle into C.A.R.S. after seeing the many positive reviews. It turns out these were very accurate. Corey was very open and honest about what needed to be done and put in the extra effort to find a quality engine at a fair price. I will definitely be going back to C.A.R.S. for any future mechanical repairs.

Super friendly staff
Car & Truck Care, near Gas City, IN
Waited almost 3 weeks for another company to not even touch my vehicle. Had a co-worker that referred CARS. Pulled it home and not only did Corey's guys come and tow my vehicle to his shop they had it done 3 days before I needed it. Highly recommend.

These guys answered my call before they were officially open, towed my truck in some of the crappiest weather and road conditions and had me rolling two days later. Fast, professional service at a VERY reasonable price. I did have an issue with something they repaired after I picked up the truck, but it was past their close time, and no one answered the phone. However, Corey did call me back later that evening, but I had fixed the minor issue myself. I feel like my scenario is 1000% the exception of their norm and i would be the .001% of an issue after repair. Also, had i been local (this truck is based in Ft. Wayne, but broke down in Elwood, and had to be on a job the next day) I am 1000% positive that Corey would have made everything perfect, had i given him the chance. I hope to never be broke down again, but if I am, I hope it's around this shop.
