Engine Repair

Engine Diagnostics & Repair — Done Right the First Time

Your engine is the most complex system in your vehicle. When something isn't right — whether it's a warning light, a rough idle, or a noise you can't quite place — the goal isn't to guess at parts. It's to find the actual cause and fix that.

At Auto Tech Services, we use professional-grade diagnostic equipment to pinpoint engine issues accurately. We service everything from a routine tune-up to a complete engine rebuild, and we'll walk you through exactly what we find before any work begins.

Warning Signs Your Engine Needs Attention

• Check engine light is on — steady or flashing
• Engine is hard to start or cranks but won't fire
• Rough idle, misfires, or engine shaking at a stop
• Noticeable loss of power, especially under acceleration
• Fuel economy has dropped significantly
• Unusual noises — knocking, ticking, or rattling from under the hood
• Smoke from the exhaust — blue, white, or black
• Engine running hot or overheating

Our Approach

We don't replace parts hoping it fixes the problem. We test and verify the root cause first. That saves you money and means the repair actually sticks. If your engine needs major work, we'll give you a clear explanation of what's involved, what it costs, and what your options are — no pressure, no runaround.

We also keep a close eye on timing belt replacement intervals. A timing belt failure can cause catastrophic engine damage with zero warning. If you're approaching that mileage, it's worth checking.

Repair, Rebuild, or Replace — What Makes Sense for Your Vehicle?

Not every engine problem calls for the same answer. A worn ignition coil is an afternoon fix; a spun bearing is a different conversation. When an engine has major internal damage, we'll lay out the honest math on all three paths: repairing the failed components, rebuilding the engine, or installing a remanufactured unit. As an authorized installer of Jasper remanufactured engines, we can often put a like-new engine in your vehicle for far less than the cost of replacing the vehicle itself — backed by a nationwide 3-year/36,000-mile warranty.

Every engine job also starts with a digital vehicle inspection, so you see photos of exactly what we found before you approve anything. And because engine and transmission symptoms often overlap — hesitation, slipping, hard shifts — we check both. If the problem turns out to be in the drivetrain, our transmission service covers that side too. Diesel owner? Head over to our dedicated diesel repair page.
