Engine Maintenance in Indiana, PA

Engine Repair & Maintenance in Indiana

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 Hammill's Automotive we provide all of the expertise and parts needed to keep your engine running happily and at peak efficiency.

Engine Maintenance Service We Offer

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





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 Hammill's Automotive, we can pull the code and diagnose the problem for you. Give us a call at 724-349-6996 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.

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 Hammill's Automotive, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 724-349-6996 or visit Hammill's Automotive today.

Whether you're in need of simple oil service, or more significant engine maintenance, call Hammill's Automotive at 724-349-6996 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 is "No." The longer explanation is that 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 Hammill's Automotive in Indiana.

What could cause a check engine light to come on?

Come by Hammill's Automotive 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 Hammill's Automotive 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 Hammill's Automotive and we can help.



Spark Plug FAQs


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

The most common sign that a spark plug needs replacing is an engine that hesitates during acceleration. Other warning signs may include engine misfires during startup, rough idling, sluggish acceleration, declining fuel economy, and engine knocking.

What else should I replace when replacing spark plugs?

If you're considering having your vehicle's spark plugs replaced, there's a good chance the spark plug wires should be replaced as well. Ignition wires become brittle over time, and worn wires can lead to engine misfires, poor performance, and reduced fuel economy.

What Our Customers Are Saying

reviewiconCar & Truck Care, near Indiana, Indiana

My car broke down early Sunday morning on US 22 while I was traveling home to Indianapolis. AAA towed it to Hammills Automotive, and Eric contacted me Monday with the diagnosis: the catalytic converter needed to be replaced. He kept me informed throughout the process, completed the repair quickly, and had the car ready by Wednesday. The price was very fair, and they kindly held the car until I could pick it up Friday. Hammills turned a stressful situation into a positive experience. I highly recommend them—if I lived closer, they would be my go-to repair shop. Eric was great to work with.

I found this garage through a friend who's daughter had gone to school in Indiana and her boyfriend was from the area. I needed a place for my college son and daughter to go with their vehicle s theyhad problems. THANK GOD we choose this place!! They were ALWAYS wonderful- they got my children in every time they had an issue, even when the garage was fully booked (because of course, problems happen right before needing to drive home across the state) and were always helpful, respectful, kind, honest, and knowledgeable. They even drove my son's car to a different county for an emissions inspection because he needed it and they don't do those in Indiana county. If you have children attending IUP and you live far away, DEFINITELY SEND THEM HERE! They will take care of them. Thank you Hammill's for taking care of my children's vehicles for the past 4 years!!

Very good experience. Eric was very kind and professional. He got me right in on short notice, got my car fixed up, and I was back on the road in no time. He even ended up charging me a bit less than he quoted me due to the labor not taking as long as he expected.

Honest and truthful! We had our subaru towed to Hammill's because we thought the brake line blew. Eric and the crew looked everything over and determined it was merely a sensor, no issues. They could've told us we needed new brake lines etc.BUT they are ethical and honest! We don't know cars so we are dependent on an honest mechanic. With Hammill's we found one!
