Engine Maintenance in Tucson

Engine Repair & Maintenance in Tucson

Your engine is one of, if not the most important component of your car. Without it working in proper order, it's impossible for you to go anywhere. If it runs inefficiently, you may face a whole host of problems that can be avoided with relatively simple maintenance. At Covenant Automotive Repair & Service we provide all of the expertise and parts needed to keep your engine running happily and at peak efficiency.

Below are the services we can perform to ensure your engine remains healthy:


Spark Plugs, O2 Sensor, Fuel Filter

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 Covenant Automotive Repair & Service, we can pull the code and diagnose the problem for you. Give us a call at 520-351-2061 or stop by the shop for our expert assistance.

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 520-351-2061 or visit Covenant Automotive Repair & Service 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 Covenant Automotive Repair & Service 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 Covenant Automotive Repair & Service in Tucson, AZ 85712. 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 Covenant Automotive Repair & Service in Tucson, AZ 85712.

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 Covenant Automotive Repair & Service, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 520-351-2061 or visit Covenant Automotive Repair & Service today.

Whether you're in need of simple oil service, or more significant engine maintenance, call Covenant Automotive Repair & Service at 520-351-2061 to learn how we can help you get back on the road quickly!

Check Engine Light FAQs


Is it okay to drive with the engine light on?

The short answer, "No." The longer explanation is the light may indicate a serious engine failure and continuing to use your car as if nothing is wrong could result in a very expensive repair bill. The check engine light means you should stop driving and have your car looked at as soon as possible by a professional at Covenant Automotive Repair & Service in Tucson.

What could cause a check engine light to come on?

Come by Covenant Automotive Repair & Service and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a simple 50K or 100K mile manufacturer maintenance check.

What is the most common problem with my check engine light?

A loose gas cap is the most common cause of a check engine light coming on. But the best method to determine why the check engine light is on is to have a professional at Covenant Automotive Repair & Service read the diagnostic code in the car's internal OBD computer.

What does an intermittent flashing check engine light mean?

Flashing check engine lights warn of severe situations requiring immediate attention. Get your vehicle to an auto repair shop as quickly as possible or get it safely parked and call a tow truck to take it to your preferred auto repair shop.

What does a solid check engine light mean?

A steady check engine light indicates a non-emergency issue. Come by Covenant Automotive Repair & Service and we can help.

Serpentine Belt FAQs


How do I know if I need to replace my car's serpentine belt?

If your serpentine belt is failing, you may notice performance issues with your vehicle. The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly. You may notice your vehicle battery failing to recharge if the alternator is affected by a bad serpentine belt. If you start to notice any of these issues we encourage you to bring your vehicle to Covenant Automotive Repair & Service as soon as possible to avoid bigger problems and breakdown.

Spark Plug FAQs


What else should I replace when replacing spark plugs?

If you are considering having your vehicle's spark plugs replaced, there's a high probability that your spark plug wires need changing as well. Ignition wires become brittle over time. Old ignition wires can break and cause misfires or declining fuel economy.

How do you know when a spark plug needs to be replaced?

The most common sign a spark plug needs replacing is the feeling that the car's engine is hesitating when accelerating, but other signs may include misfiring at start up, rough idling, sluggish acceleration, declining fuel economy and engine knocking.

    We found our former auto repair shop closed only to "randomly" pull into Mark Knaak's, Covenant Automotive, LLC today. While it makes sense to get an appointment, they performed mechanical service on two of our cars without hesitation. They were pleasant to work with, asked appropriate questions, provided information and excellent service second to none. Mark is a VERY experienced mechanic and able to work on almost ANY make or model. He specializes in "high end" luxury vehicles. Raise your prices, Mark! You deserve EVERY penny. THANK YOU. We'll be back!

    Mark was honest, kind, worked very efficiently, and made my experience at Covenant Automotive not only enjoyable but heaven sent. I will certainly be taking my Nissan to him and his team as long as they are in business in Tucson. Thank you Mark for your kind heart and excellent service!

    Very impressed! I just dropped in before 3pm on 2/19/2018 with my 2001 F150 Lariat, thinking I might need a fuel filter replacement..."Service Engine Soon" light was lit. When they checked, it was determined the truck was misfiring on #8. I thought I'd have to arrange another day to bring it in for the estimated 3 hour job; Mark assured me that he could get two guys to work on it right away, and if they had to go a little past 5, they'd do whatever was needed to get me going. Well, a whole set of plugs and a new coil, and they finished at 4:50! Amazing work!

    My stepdad brings in our cars to Mark and he does a fabulous job taking care of them! I took my Nissan Maxima in for an oil change and to get my splash guard nailed back into place. They took excellent care of my car and I am very impressed with them! Will be back with my husband's car for an oil change, and will keep coming back! The oil change is a great price for the service that you receive!

    Mark has worked on my Mercedes E350...and now a doge journey (only an oil change and inspection before cross country trip.) The service and above all, honesty you'll get here is just the best. We're moving east and will miss them!
