Engine Diagnosis, Repair and Replacement

Preferred Automotive repairs and replaces engines. We do not rebuild engines. If your vehicle has a warning light, leak, unusual noise or loss of power, we can diagnose the concern and explain the appropriate repair or replacement options.

Start With a Diagnosis

Engine symptoms can have several causes. We inspect the vehicle, discuss the findings and provide an estimate before beginning repairs. Diagnostic work is charged separately, starting at $212; we explain any additional diagnostic time and cost before proceeding.

Engine Repair Services

Our services include engine repairs and replacement, timing belts and timing chains, water pumps, radiator repairs, coolant flushes, and diagnosis of overheating, oil leaks and coolant leaks. The work recommended depends on the vehicle and the results of the inspection.

Estimates and Communication

We explain the expected parts, labor, fees and taxes, obtain your approval, and keep you informed about progress and any delays. Replacement timing depends on the job and parts availability.

Call 301-881-8530 to discuss your vehicle or arrange an appointment.
