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 Hale's Diesel & Auto 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.

Ignition
Your vehicle's ignition system is responsible for starting the engine by delivering an electrical spark that ignites the air-fuel mixture in the combustion chamber. Issues can involve a worn ignition switch, a faulty ignition coil or broken or corroded wiring. These problems can lead to symptoms like the engine failing to start, intermittent stalling, dashboard warning lights, or even complete power loss while driving.

Ignition Wires & Cables
These vital parts 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. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine vibration.

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) in order to function optimally.

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 Hale's Diesel & Auto Repair, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 432-227-2752 or visit Hale's Diesel & Auto Repair today.


Spark Plug Related FAQs


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.

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.

Serpentine Belt Related 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 Hale's Diesel & Auto Repair as soon as possible to avoid bigger problems and breakdown.

Check Engine Light FAQs


What could cause a check engine light to come on?

Come by Hale's Diesel & Auto Repair 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.

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 Hale's Diesel & Auto Repair in Midland.

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 Hale's Diesel & Auto Repair read the diagnostic code in the car's internal OBD computer.

What does a solid check engine light mean?

A steady check engine light indicates a non-emergency issue. Come by Hale's Diesel & Auto Repair and we can help.

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 Our Customers Are Saying

The best service, hands-down. Customer care was top notch, and they got my Yukon fixed up quickly. They were so much easier to work with than the dealership.

Well, where to begin. We all work in WTX for a reason, and we put some pretty heavy wear and tear on our trucks. Some trust the 5 minute lube guys, or the truck house. End of the day I don't. I was pointed in Hale's direction and will NEVER search for another crew. They gave me my twice look over and showed me what they saw, was wrong, was possibly going to go wrong, what level of seriousness. They worked with me, we talked pros and cons. They made some valid points even if i didn't want to hear them, because i know they are right! Got my truck back, clean, Quality Checked, bottle of water the works. So excited to get the truck back. The next day, alas, i had a small problem. The owner reached out to me, the service writer reached out, mind you this was before the sun even came out. They got me lined up with a tow from my house to the shop. Put me front of the line. They made sure i had transportation to and from everything i needed. Offered a truck to use if i needed. Had my truck up and running 24hrs later. The truck back to full life, shining and sparkly and roaring strong. I CANNOT say anything bad, they took initiative, they were calm and cool not pressuring me into anything. Small hiccup that could have changed the course of my feelings (probably not though, because things happen) At the end of the day in WTX where Service Quality and Customer service are severely lacking in every industry. Jason, Jesse and that team went above and beyond! They got me hooked and i won't accept any service less than what they produced in West Texas! Thanks again Hale's Team

Owner personally went to pick me up in his personal truck so I wouldn't have to waste money on a taxi . They diagnose your vehicle and give you the option to approve whatever repairs you want to get done. When I picked up my truck after repair was done I had a cold Gatorade and water in the center council. They vacuumed truck and cleaned all the windows. Very impressed with their service. I'll definitely go back..
