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 Northwest Automotive LLC to help you protect your investment. Call us at 419-782-7827 or visit our shop in Defiance 43512.

These are some of the engine maintenance services we offer.

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 Northwest Automotive LLC, we can pull the code and diagnose the problem for you. Give us a call at 419-782-7827 or stop by the shop for our expert assistance.

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 Northwest Automotive LLC 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 419-782-7827 or visit Northwest Automotive LLC 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 Northwest Automotive LLC 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 Northwest Automotive LLC in Defiance, OH 43512. Here, you will have the wires and cables changed by a top-rated mechanic.

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 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to Northwest Automotive LLC in Defiance, OH 43512.

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 Northwest Automotive LLC, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 419-782-7827 or visit Northwest Automotive LLC today.

Awesome shop!! Not only was the estimate the lowest I received, the entire exhaust system was replaced (headers on back), the work was completed in under 2 hours. I m a U.S.Army Veteran and my car had a misfire situation going on due to bad coil pack, well Tim & his guys found me a coil pack and put it on NO CHARGE!! I would recommend this shop to any & everyone!

I have a 2011 Jeep Liberty, the A/C stopped working, so I called up Tim and told him. He said can you bring it in today at 1:00pm? I said yes. So I took it in, they found that all the Freon was out of the unit. So they put more Freon in plus added some dye to find if the system may have a leak. So I paid the bill. Tim said, if you have any further problems bring it back. So the next day I started my Jeep up. The A/C stop working. So I called them back on Saturday. Can you bring it back on Monday at 2:00pm? I replied yes. Returned back to Northwest Automotive. They took my jeep in and recharged the A/C unit, and checked the system for any possible leaks. So Tim filled me in on no signs of dye so go ahead drive it and if any further problems bring it back. So how much money do I owe you? He replied nothing. The next day I drove my Jeep the A/C stop working again. So I called them back and told them. Can you drop it off so we can get to work on it Monday morning. I said yes. So I called them up Monday around noon and asked how are things going with my jeep? He replied that we believe we have found the leak. So he asked you said when it would set over night that the next day it not work? I replied yes. He asked if you don't need your Jeep back today, we will let it set overnight and check and see if it is still working in the morning. So I replied yes. I called them back the next day and asked how are things going with my jeep? Tim replied it is working fine. He asked if I would pick it up later today, l said that is fine because I will not be in town till around 3:30pm. Because I was at work. So went to pick up my Jeep. Tim said I believe the problem was from the low pressure valve. It should be alright. I replied so how much do I owe you. He said nothing, if you have any further problems bring it back. I believe he is a fair and honest person. I will respect that and I will bring him some more business. Thanks again.

Northwest Automotive didn't charge me to look over my Geo Traker, even though I didn't end up having anything done to it. Will be going back to them.
