ENGINE MAINTENANCE

Engine maintenance is vital to keep your car or truck operating at peak performance. It also impacts the longevity of your vehicle's engine. Trust the experts at Walt's Service Inc. to help you protect your investment. Call us at 573-449-4171 or visit our shop in Columbia 65201.

These are some of the engine maintenance services we offer.

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 Walt's Service Inc. to help your diesel engine last a long time.

Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine. Make sure your vehicle's fuel injection system is maintained properly. For all your fuel injection maintenance and replacement needs, call 573-449-4171 or visit Walt's Service Inc. today.

Ignition
An ignition system is a system for igniting (using an electric spark) a mixture of fuel and air in a gasoline engine. A properly working ignition system means a properly starting engine and high performance from your car. For all your ignition system maintenance and replacement needs, call or visit Walt's Service Inc. today.

Ignition Wires & Cables
Ignition cables also known as spark plug wires are an important part of your car's ignition system. They transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. The car will eventually fail to start. If it does start, it will run poorly. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine may vibrate. If your car needs new ignition cables and wires, call or visit Walt's Service Inc. in Columbia, MO 65201. Here, you will have the wires and cables changed by a top-rated mechanic.

Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At Walt's Service Inc., we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 573-449-4171 or visit Walt's Service Inc. today.

Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 5,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to Walt's Service Inc. in Columbia, MO 65201.

Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At Walt's Service Inc., we can pull the code and diagnose the problem for you. Give us a call at 573-449-4171 or stop by the shop for our expert assistance.


What Our Customers Are Saying

Was driving from NY to LA when my Bus started dying on the highway. Lookup the nearest VW mechanic and come here. Walt is great! He took a look at my Bus, even though it was late and he was busy-and told me the last guy who rebuilt the engine screwed up. I trusted Walt to rebuild the engine, and he did it cheaper and quicker than the first mechanic, and much better! I now have 10-15mph higher top speed and it runs a lot smoother. Driving from MO to LA I went from losing 1qt/1000 miles to losing no oil! Superb job, honest guy, nobody knows more about air-cooled VWs than he.


-Brandon C.

My daughter, a MU student, and her used 2007 high mileage Audi A4 broke down, the car was towed to Walt's. Walt called me the next day and went over his diagnostics and recommendations. He only recommended what needed to be done and did not recommend useless/costly repairs. When the car was complete, he called me with the final bill which was totally reasonable. He was timely and great to work with! I highly recommend this repair shop, it is so hard to find honest and qualified technicians and mechanics these days and Walt is truly one of the best I have ever worked with. I will definitely be back, thank you so much!


-Robert H.

I have an old (2001) high mileage (155k+) VW Golf, and I only take it to Walt's. The staff is friendly, honest, fair, and fairly quick with repairs. They give you options and explain the pros and cons of optional repairs. They keep my old Golf running well, with fair costs for repairs. I would (and have) recommended to anyone with a VW or similar German car.


-Noel B.

I had my MINI Cooper serviced here. These guys are great. They showed me everything about my car (as I know nothing about cars). The Baron MINI in Kansas City told me I needed new front and back brakes and rotors. After showing me how much brake pad I had left on the back brakes, the guy at Walt's said "that's nuts and these should last at least another year". They also did quality work and cost a couple hundred bucks less! I am very pleased!


-Grant V.

I would not take my car anywhere else. They are honest, friendly and work with you to make the best/most cost effective repair solutions.


-Shannon W.

-Austin B.

Friendly honest shop. Best place to get European cars worked on in Columbia.


-Scott W.

I have seen the work they do on Porsche 911's, many times, first hand. They are friendly and helpful. Very knowledgeable staff. If they tell you something, listen to them. The best Porsche service in MO.


-Three Hour Tour Official

To say that Walt is honest would be the understatement of the century! As a female, I'm always nervous about being taken advantage of. And with a 2005 BMW Z4, sometimes work needs to be done!Thank you Walt. You have created a loyal customer.


-Jami C.

Would not take my Passat Wagon anywhere else! They have always finished my repairs in a very timely manner and at the most reasonable rates. They are truly professional in all areas of service. Thanks again, guys, for taking care of me and my vehicle.


-Pamela W.

This place is trustworthy, dependable and communicates everything to you very well. I graduated from MU and now drive all the way from Saint Louis so that I can get my car serviced at this location. No other service center can compare to these guys.


-Ryan P.

A good shop with experienced techs and good labor rate compared to larger places. They know what they are doing!


-Anthony V.

Walt's shop has worked on three of my vehicles during the past couple of years. Results were excellent, and I found their prices competitive with other shops in the area. Everyone there is helpful and courteous. My vehicles include domestic brand trucks and SUV's so be aware Walt's work is not limited to just imported models.


-John M.

This shop has been consistently top notch for service, honesty, and pricing. Although the specialize in foreign cars, I also take my other vehicles to them, as well. I highly recommend them.
