Engine Maintenance

It’s crucial to keep the engine in good working order for every car owner. Simple engine maintenance can save you from potential problems down the line. Not only will this improve the performance of your vehicle, but it will also help extend your engine’s lifespan.

At Mechanic Northwest, we are more than qualified to perform top-notch automotive services. We have ASE-certified mechanics working in a state-of-the-art facility and using top-quality equipment to keep your engine performing at its best. Since 2013, we have provided reliable services to drivers in Federal Way and the neighboring areas in King County, WA.

Engine Maintenance Services We Offer

To keep your car running smoothly and avoid costly repairs down the road, we offer engine maintenance services for the following:

  • Fuel Injector

If your car isn’t performing the way it used to, it might be time for some injector cleaning. Your car’s injectors might be clogged. Mechanic Northwest offers specially-developed injector cleaning solutions to open up clogged injectors and get your car back to making the most power possible.

  • Ignition System

Your car’s ignition system is responsible for getting your vehicle started. It creates a spark that ignites the fuel and air mixture in the engine. Without it, your car won’t be going anywhere.


If you’re having problems with your ignition system, get it checked out immediately. Ignition problems can be caused by a variety of issues, and only a professional will be able to diagnose and fix the problem quickly. Contact our team today and let our certified mechanics handle it.

  • Ignition Wires and Cables

The ignition cables, also known as spark plug wires, play a crucial role in the ignition system by transferring the spark from the ignition coil to the spark plugs. However, these cables become brittle and break down over time. This can prevent the spark from reaching the engine cylinders, causing the engine to misfire. Eventually, your car may fail to start altogether.

Regular engine maintenance can help prevent this problem. We have experienced mechanics who can check and replace your ignition wires and cables to keep your engine running smoothly.

  • Spark Plugs

Your engine needs spark plugs to deliver electric current and create the spark that ignites the fuel-air mixture in the combustion chamber. If your spark plugs are old or haven’t been changed in a while, they can cause ignition problems. At Mechanic Northwest, we have automotive experts who will check your spark plugs and replace them to keep your engine running smoothly.

  • Preventive Engine Maintenance

As most car part manufacturers will tell you, the best way to keep your engine running in peak condition and improve its fuel economy is to keep up with regular preventive engine maintenance. Doing so can extend the lifespan of your car significantly.

I usually go to pep boys.. but the customer service there has gone down A LOT. They quoted me $1100 for what they thought needed to be done. And if I still liked pep boys I would’ve paid that but then I thought I better give my money to a shop I actually like. I went to mechanic northwest and they were soooo helpful and nice and I can tell they weren’t trying to take advantage of me or overcharge me. Which me being a young girl is usually what happens at mechanic shops. They were so transparent and kept me in the loop the entire time. The lady even took the time to explain everything and show me videos of what was done. If you’re tired of big corporate chain mechanic shops, give these guys a try. I love small family owned businesses. I ended up paying way less than what pep boys was going to charge me And my car runs great! Also I had just taken my car to pep boys a couple months ago and paid $1700 and they said I should have no more problems.. just to end up with my car having trouble again after 3 months. So yea it was time for a change. I highly recommend this shop!

I have only been in Washington for a few years and was looking for a small shop with quality work and fair prices. Called Mechanics Northwest and scheduled a diagnostic. They promptly assessed the issues and provided a quote. Repairs were completed earlier than promised and within the quoted cost. I am happy to have found a shop for all my future repair needs!!

This place deserves the highest of reviews. This is my second car I have taken to them right after purchasing them, without a doubt I get very well taken care of. The guys are very professional and Alnurfo is super knowledgeable and respectful. If your looking into getting your car fixed the right way the first time this is defined the place to go to.

From the moment I met the owner of Mechanic Northwest in the rear of the shop in the parking lot until I drove away fully satisfied that my 2008 Infinity FX35 had its brake job completed ✅ I was treated with respect and friendliness in the process of doing professional work. I definitely feel that I picked the right shop to do business! Thank you for such a pleasant experience. It was totally stress free. I fully trust these people to do work on all my vehicles in the future. And I highly recommend their service. Thankful for Mechanic Northwest!! They cared about my 🚘 !

Very nice people and very thorough. They made sure I knew what was wrong with my car and even went above and beyond to give my dealership an estimate of how much the repairs would cost.

I have an oil change every 4 to 6 months. I recently moved to Fed Way and needed to find a new place. I came across this shop and made an appt. My car seems to run better after having my oil changed here. Not sure what oil they used but I definitely feel a difference in my car. I'm taking it back for a recommended fluid flush. My car is an 07 so I'm sure it needs fresh fluid.

Brought my car in to get the power window fixed (came off the track) and an inspection, got it back same-day. Great service, communicative, friendly and courteous front desk staff. Will be going back if my car ever needs new repairs.

Again, Mechanic Northwest came through for our family when our older truck broke down. They were able to quickly diagnose the problem and call to discuss what can be don. They continue to be reasonably priced & have a fast turn around. I know I can count on them to take care of our vehicle needs.

Over heated on the side of the highway and got towed here. These guys got me in right away, diagnosed the problem, fixed it, and got me on the road in no time at a fair price. They were extremely friendly and transparent. I hung out in the garage with them while they worked on it. Definitely recommend their services.
