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 Jensen Service & Diagnostic can drop in a completely remanufactured JASPER gas or diesel engine, transmission or differential and get you back on the road again quickly! Call Jensen Service & Diagnostic at 402-333-9999 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 402-333-9999 to talk to the mechanics of Jensen Service & Diagnostic 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 Jensen Service & Diagnostic'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 Jensen Service & Diagnostic 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 Jensen Service & Diagnostic.

Engine Repair
When your vehicle shows any sign of trouble, bring it to Jensen Service & Diagnostic for full-service engine repair in Omaha, NE. 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 you 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, Jensen Service & Diagnostic 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 Jensen Service & Diagnostic. Visit us at 1307 S 120th St 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 Jensen Service & Diagnostic 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 402-333-9999 or visit Jensen Service & Diagnostic 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 Jensen Service & Diagnostic.

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 402-333-9999 to talk to the mechanics of Jensen Service & Diagnostic 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 402-333-9999 to talk to the mechanics of Jensen Service & Diagnostic 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 Jensen Service & Diagnostic in Omaha, NE. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.

What Our Customers Are Saying

I had a big problem with my BMW's timing chain and variable drive system, and Jensen Service & Diagnostic was able to work with my extended warranty company, keep me apprised of repair status, and complete some very difficult disassembly, reassembly and testing. Hats off to Jensen Service & Diagnostic for their professional and personable approach, they are very trustworthy and a pleasure to work with.

Jensen Service & Diagnostic is very trustworthy. Our 2011 Toyota Corolla was leaking oil. The dealership said it would cost $2,142 to repair. We sought a second opinion from Jensen Diagnostic. They said it was a minor repair....basically it just needed an oil change for $37. It was completed the same day and hasn't leaked oil since. Jensen Service & Diagnostic saved us more than $2,000! We are very grateful.

We were recommended by a different mechanic to visit Jensen Service for a big electrical problem our car was having. I am so glad we had them look into it because they were able to find the problem within the day and had it fixed and running like new again that same week. Prices are fair as well! Would recommend these friendly guys and we plan to use them again in the future for any vehicle repairs. It's a huge relief finding a mechanic you can trust! Thank you Jensen Service!

Our family has used Jensen Service & Diagnostic for several years on our Honda Accords and our Duramax equipped pickup with zero come-backs. I drive my vehicles up to 1200 miles a week for work. I'm always confident in their work when I hit the road after each appointment. They also treat my wife and children with respect when they bring their cars in for work. If you're looking for professionally performed repairs and maintenance in a clean, comfortable environment this family-owned business is worth checking out.

I have to give the guys a Jensen a giant shout out. My dealer told me my car required a brake job and quoted me $1900. I thought this sounded steep so declined and took the car over to Jensen to get it repaired, knowing it would be less and the job would be done right. To my surprise I receive a call and they told me my car did not required repair for a least another 15,000 miles. Jensen, thank you for your honesty. I will be back in 15,000 miles!
