Our Engine Diagnostics & Repair Services

Comprehensive Engine Diagnostics

We use state-of-the-art diagnostic equipment to quickly identify error codes, fuel system issues, misfires, and other engine problems. This allows us to pinpoint the root cause and provide accurate repairs.

Check Engine Light Troubleshooting

A check engine light can indicate anything from a minor sensor issue to a serious mechanical failure. Our technicians will run a full diagnostic scan, interpret the error codes, and take corrective action to resolve the issue.

Fuel System Repairs & Optimization

A failing fuel pump, clogged injectors, or faulty sensors can cause poor fuel economy and reduced engine performance. We inspect and repair fuel injectors, pumps, filters, and regulators to maximize efficiency.

Ignition System Repairs

A faulty ignition coil, spark plug, or starter motor can prevent your engine from running smoothly. Our team replaces worn ignition components to restore power and reliability.

Cooling System Inspections & Repairs

Overheating is a leading cause of engine failure. We inspect and repair radiators, thermostats, water pumps, and cooling fans to prevent overheating and extend engine life.

Timing Belt & Chain Replacement

A worn or broken timing belt/chain can cause catastrophic engine failure. We perform preventive timing component replacements to keep your fleet running without unexpected breakdowns.
