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 Arizona Auto & Radiator Repair to help you protect your investment. Call us at 520-459-2216 or visit our shop in Sierra Vista 85635.



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 Arizona Auto & Radiator Repair 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 520-459-2216 or visit Arizona Auto & Radiator Repair 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 Arizona Auto & Radiator Repair 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 Arizona Auto & Radiator Repair in Sierra Vista, AZ 85635. 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 Arizona Auto & Radiator Repair, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 520-459-2216 or visit Arizona Auto & Radiator Repair 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 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to Arizona Auto & Radiator Repair in Sierra Vista, AZ 85635.

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 Arizona Auto & Radiator Repair, we can pull the code and diagnose the problem for you. Give us a call at 520-459-2216 or stop by the shop for our expert assistance.

What People Say About Us


  • -Susanne, Sierra Vista AZ

    AZ Auto and Radiator performed a thorough check of my vehicle and found some issues that I suspected were present, but were never diagnosed by another local auto business. The owner took the time to show me (on the vehicle) what he recommended and why. Professional, friendly service, and they didn't pressure me to have everything fixed immediately. Highly recommended!


  • -Guy, Huachuca City AZ

    As usual, Danny and staff did an AWESOME job! Danny and AnnMarie are wonderful people and are as honest as the day is long. AZ Auto and Radiator have been doing the maintenance on all of my vehicles since 1997 or 98, and I will continue to take my vehicle maintenance needs to them. They do excellent work, and will tell you the truth about your vechicle maintenance needs; without all the extra stuff that other auto shops will try to sell you. Take your vehicle to Danny and crew for you next vehicle maintenance needs--You Won't Be Sorry!


  • -Mike, Tombstone AZ

    Danny and the crew at Arizona Auto are tops for reliable workmanship and customer service.


  • -Whitney, Sierra Vista AZ

    Just had my oil change and a much-needed window repair before monsoon season hits. I have an older vehicle and I like that Danny and AnnMarie take a wholistic approach at caring for my car--they try to watch for possible issues and let me know what might be coming up. They are also mindful about determining the cause behind any needed repairs (if it is not something attributed to basic wear over time) so that we don't end up repairing the same issue over and over.


  • -Mark, Elgin AZ

    Not only can we trust that our truck is getting excellent, and current, service with Arizona Auto; each time we go, there is some thoughtful improvement to the waiting area. We couldn't be happier with them!


  • -Doug, Benson AZ

    Seventeen years later we still depend on our extended family at Arizona Auto to fix our problems.


  • -Carol, Bisbee AZ

    Got my vehicle in right on time and completed the work in a timely matter. Friendly and helpful staff. Repair was very reasonably priced. Plan to return when vehicles need service.


  • -Linda, Sierra Vista AZ

    I find the owners and staff trustworthy and ethical. My car is always ready when promised.


  • -Marianne, Sierra Vista AZ

    I trust the people who work at Arizona Auto and Radiator. A few years ago, they sold a car for us. They told us they expected to sell it for $4,000; we thought that would be a good price to get for the car. They sold it for $5,000 and gave us the extra $1,000. We would never have known that they sold it for a higher price and would have been happy to receive the $4,000 originally estimated. I don't think that level of honesty is common in many businesses.


  • -Edie, Sierra Vista AZ

    Major RAVE for Dustin and Danny at AZ Auto on Bartow. My 14 y/o vehicle had been ignored and abused for some time. Danny is a great diagnostician, Dustin worked with me on some of the maintenance issues it had. Nobody ever spoke down to me because I am a female (They did not know I was a Veteran Army mechanic). Nobody tried to oversell. My car drives like new. Very impressed.
