Engine Repair Services We Offer


Oil Changes

Regular oil changes provide a snapshot of your engine's health. Fresh oil should darken slightly, maintaining a consistent thickness without any gritty particles. Solid particles in the oil can indicate serious internal wear, which could lead to significant engine damage. At Dennis Road Automotive, our oil analysis helps in detecting and addressing such issues early.

Engine Coolant Check

Engine coolant is critical in maintaining your engine within safe operating temperatures. Overheating can lead to serious issues like radiator damage from overpressurized coolant. Using the correct coolant prevents these risks, safeguarding your engine's performance.

Ignition Wires & Cables

Healthy ignition wires and cables are essential for transmitting electrical sparks to your engine's spark plugs. Symptoms of failing wires include misfires, poor fuel efficiency, and engine vibrations. If you experience these, our mechanics at Dennis Road Automotive can replace faulty wires and restore engine function efficiently.

Spark Plugs

Spark plugs are key in delivering the necessary spark for combustion. Worn spark plugs can cause starting troubles and poor engine performance. Our team can check and replace your spark plugs to maintain optimal engine efficiency.

Cylinder Head Repair

The cylinder head is crucial in sealing the engine and managing airflow. Proper function prevents compression issues and driving difficulties. Our experts offer thorough inspections and repairs to ensure your engine's top performance.

Engine Replacement

Even reliable engines can fail. If you face engine troubles, don't delay in getting a professional replacement. At Dennis Road Automotive, we provide dependable engine replacement services to revive your vehicle's performance.

Engine Repair 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 engine 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 Dennis Road Automotive in Dallas.

What Could Cause a Check Engine Light to Come On?

Come by Dennis Road 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.

How Long Should an Engine Repair Take?

The time it takes to rebuild an engine varies greatly, ranging from a few days for simple jobs to several weeks for intricate work. Regardless of the timeframe, a thorough understanding of the engine's components and strict adherence to the manufacturer's guidelines are essential for a successful and long-lasting rebuild.

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.

Where do I start ADAM ADAM ADAM remember that name his customer service was outstanding, spectacular, and above and beyond, when I first pulled up he had a Genuine spirit, His presence made me feel very comfortable, I didn’t get this feeling “this guys just here to do a job and get paid” but that he has a heart to care about his clients, He listened, took notes, and understood what I was requesting fully. I told him how I went to another mechanic shop and how I was treated there and how much they were trying to charge me to fix an issue he emphasized with me and understood that not everyone have money to blow especially fixing unnecessary things that doesn’t necessarily pertain to the issue at hand I was being upsold at another mechanic shop and over charged but ADAM rest assured he doesn’t do that there he knows when you treat a customer right they’ll continue to be loyal. I was expecting to have it in the shop for a while and having to Uber to work and back it gets expensive when you’re 30 mins away from work. He was able to fix my Auto Stop Start and Check Engine light for dang near HALF the price of another mechanic shop quoted me and didn’t upsell me and fixed it in 2 DAYS! He was so nice I offered a tip 3 times and he denied it real genuine he also checked in on me to make sure things were straight. I was extremely happy to know it’s fixed and that I’m saving HALF the price I was quoted I found my Guy and Mechanic shop at Dennis Auto Motive HIGHLY RECOMMEND quotes-image

I’ve trusted Dennis Road Automotive for many years, though it’s been a while since my last visit, mainly because they’re not open on weekends. I’ve always appreciated their straightforward service, and I still miss Riley, who brought a great personal touch to the experience. On my most recent visit, I was charged $374 for a new battery for a Lexus ES350. I’m not sure how that compares in today’s economy, but it gave me the same feeling you get when dining out these days, quality isn’t necessarily better, yet the prices seem to jump significantly. The work was completed, and the team was professional, but the cost left me wondering if the value aligns with what it used to be. I still want to support businesses that have served the community for so long, and I hope they continue to provide honest, dependable service at a price that feels fair in the current market.quotes-image
