Heavy Duty Services: Engine Overhaul & Replacement

For the big jobs, take your vehicle to J M & H Automotive! Our expert services are ideal whether you have a late model import or newer domestic vehicle. And because we guarantee the work we perform, you can rest assured you are receiving the highest quality engine overhaul and replacement services in the Clovis, CA 93611 area.

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 559-298-8922 to talk to the mechanics of J M & H Automotive 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 J M & H Automotive'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 J M & H Automotive 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 J M & H Automotive.

Engine Repair
When your vehicle shows any sign of trouble, bring it to J M & H Automotive for full-service engine repair in Clovis, CA. From diagnostic check engine light repair to precision engine part repair, our expert auto mechanics are ready to help 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 J M & H Automotive. Visit us at 1576 Menlo Ave
Suite A 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 J M & H Automotive 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 559-298-8922 or visit J M & H Automotive 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 J M & H Automotive.

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 559-298-8922 to talk to the mechanics of J M & H Automotive 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 J M & H Automotive in Clovis, CA. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.

    Steve is fantastic. Couldn't get my headlight bulbs unscrewed myself, he told me to come by and he got them both done. Even though I'd never been a customer before, he charged me zero! Definately a new place to take my cars for maintenance & repairs. As stated in other reviews this is a shop that has integrity and is not out to overcharge you. I'll be back.


  • -Gene G.

    Steve helped me out in a pinch. I just returned from a 2 week road trip and needed to get a new alternator before hitting the road again. I didn't have much time on my hands, but Steve worked with me. I was pleased with the service, timeliness, and honesty. Thanks Steve!


  • -Susan H.

    Outstanding! They saved my life because I was driving with loose ball joints from MT. They were able to help me and I am back on the road. Thank you so much Mike and Erik! Terrific people and very helpful.


  • -Trevor G.

    Great shop. I was referred to JM&H by some friends and was it worth it. I called and spoke with Stephen, got an appointment set, on the day of my appointment I get there describe what I think is wrong and supply eric the Mechanic who worked on my car, with the parts that I brought. An hour later I was all fixed up and back out on the road!! Big shout out to Stephen, Mike and Eric! Thanks guys!

    Good service and took my vehicle in on a late afternoon. Got the A/C repair done in under an hour. Half the price of Jiffy Lube for the same repair. Best place!


  • -Marnie J.

    I can definitely say that they are honest, trustworthy and very friendly there! Being a single female, it's always scary going somewhere to have your car worked on because you never know what to expect or what some company may try to con you into buying. With this company, that is the last thing you need to worry about...I 100% trust them and the advice they give! The service was phenomenal and they take care of you immediately. I'm definitely going back to them for my car needs!!
