Engine Repair

Engine Problems? We Find the Cause.

Your engine is the heart of your vehicle. When something isn't running right, guessing and replacing parts can quickly become expensive.

At Zavagli Auto LLC, we provide professional engine diagnostics and repair for cars, trucks, SUVs, and diesel vehicles. From check-engine lights and drivability problems to major engine repairs and engine replacements, we use advanced diagnostics and hands-on testing to determine what's actually wrong.

Engine Diagnostics

Engine problems don't always come with an obvious answer. A check-engine light can be caused by anything from a simple sensor or wiring issue to a serious mechanical problem.

Our diagnostic services can include:

Check-engine light diagnostics
Engine performance diagnostics
Misfire diagnosis
Rough idle diagnosis
No-start diagnosis
Hard-start diagnosis
Stalling diagnosis
Loss-of-power diagnosis
Fuel system diagnostics
Ignition system diagnostics
Air and intake system diagnostics
Electrical and wiring diagnostics
Sensor and actuator testing
Compression testing
Mechanical engine testing
Cooling system diagnostics
Oil pressure and lubrication system diagnostics

Engine Repairs

Once the problem is properly diagnosed, we can perform the necessary repair rather than simply replacing parts until the problem goes away.

Engine repairs may include:

Cooling System Repairs
Radiators, thermostats, water pumps, cooling fans, hoses, leaks, and related components.

Fuel System Repairs
Fuel pumps, injectors, fuel pressure problems, fuel system components, and related diagnostics.

Ignition System Repairs
Spark plugs, ignition coils, ignition components, and related electrical issues.

Electrical & Wiring Repairs
Engine wiring, sensors, connectors, grounds, power supply issues, and intermittent electrical problems.

Oil & Lubrication System Repairs
Oil leaks, oil pressure problems, oil system components, and related engine concerns.

Intake & Air System Repairs
Intake components, sensors, air leaks, turbocharger-related issues, and other air-management problems.

Gasket & Seal Repairs
Diagnosis and repair of leaking or failed engine gaskets and seals.

Timing System Repairs
Diagnosis and repair of timing-related engine problems and components.

Major Engine Repairs & Engine Replacement

Some engine problems require more than a simple component replacement.

Zavagli Auto also handles larger engine repair projects, including:

Major engine repairs
Engine component replacement
Engine tear-down and inspection
Engine resealing
Head gasket repairs
Timing component repairs
Engine replacement
Engine swaps
Diesel engine repairs
Performance and upgrade-related engine work

For larger repairs, our shop provides the space and equipment needed to properly perform the job.

Cars, Trucks & Diesel Engines

We work on a wide range of vehicles, from everyday cars and SUVs to trucks and diesel-powered vehicles.

Whether you're dealing with a common engine problem or a complicated issue that has already been diagnosed incorrectly, we'll work through the system to determine what is actually causing the problem.

When Other Shops Can't Find It

Some engine problems aren't obvious.

Intermittent problems, wiring issues, multiple fault codes, unexplained misfires, recurring check-engine lights, and drivability concerns can require a deeper diagnostic approach.

We combine scan diagnostics, electrical testing, mechanical testing, and hands-on inspection to narrow down the actual failure.

Our goal isn't to sell you parts you don't need.

Our goal is to find the problem and fix it.

Mobile When Possible. Shop When Necessary.

Not every engine repair needs a shop.

Smaller repairs and diagnostics may be performed through our mobile service, while major engine repairs, engine swaps, and jobs requiring additional equipment are performed at our shop.

Mobile Service
Convenient diagnostics and repairs at your location when the job can safely be completed on-site.

Shop Service
Major repairs, engine work, engine swaps, and repairs requiring additional equipment.

Engine Problems Don't Get Better by Ignoring Them.

A small engine problem can become a major repair when ignored.

If you're experiencing a check-engine light, overheating, misfires, unusual noises, loss of power, oil leaks, hard starting, or another engine-related problem, let us diagnose it before the problem gets worse.
