Our heavy duty services include:

Authorized Jasper Dealer
Give Your Vehicle a New Lease on Life with JASPER. That big oil slick in your driveway or those strange noises from under your hood don't have to mean you'll be saddled with a new car payment soon. Instead, your trusted installer at Blackmon's Garage can drop in a completely remanufactured JASPER gas or diesel engine, transmission or differential and get you back on the road again quickly! Call Blackmon's Garage at 210-341-2391 to schedule an appointment. Proudly remanufactured in the U.S.A.

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 210-341-2391 to talk to the mechanics of Blackmon's Garage 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 Blackmon's Garage'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 Blackmon's Garage 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 Blackmon's Garage.

Engine Repair
When your vehicle shows any sign of trouble, bring it to Blackmon's Garage for full-service engine repair in San Antonio, TX. From diagnostic check engine light repair to precision engine part repair, our expert auto mechanics are ready to help you.

Engine Repair and Rebuild
After years of use, your car's engine inevitably deteriorates. If your car needs a new engine and you are not ready to invest in a new car, consider having the engine rebuilt. This involves replacing or resurfacing all the rundown parts in an engine. Regardless of your engine replacement needs, Blackmon's Garage has experienced engine rebuilders ready to assist you.

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 Blackmon's Garage. Visit us at 11231 West 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 Blackmon's Garage 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 210-341-2391 or visit Blackmon's Garage 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. To have your transmission maintained by experts, visit Blackmon's Garage.

Transmission Repair
Our services include transmission repair on both manual and automatic transmissions. The first step in getting you back on the road is assessing your transmission to accurately determine the source of the problem. In some cases, we are able to repair your transmission simply with adjustments, replacing external seals, or replacing accessible parts. To have this done by specialists, call 210-341-2391 to talk to the mechanics of Blackmon's Garage today.

Transmission Repair and Rebuild
When it comes to automatic transmission repair, there are several options: buying a new one, buying a remanufactured one or having yours rebuilt. Each of the above options has its own share of advantages and disadvantages. Of the three options, rebuilt transmissions are the most economical. A rebuilt transmission involves removing the transmission from the car, disassembling it, replacing worn out parts, reassembling it, and then reinstalling it. To have this done by specialists, call 210-341-2391 to talk to the mechanics of Blackmon's Garage today.

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 Blackmon's Garage in San Antonio, TX. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.

These gentlemen know exactly what they are doing. They are very thorough and fair. They are not out to rip off the people that do not know much about motors or vehicles. I heard about them through word of mouth but I had to write this review to let everyone else know. Give these guys a chance and you will not be disappointed. I went here after going to a dealership mechanic. They are friendly and personable. UPDATE. I went back to have my front brakes changed. They gave me a fair price and didn't disappoint. These guys are solid. I recommend them over the dealerships and the franchise places.
