Check-engine diagnostics
OBD-II scan, road test, and a written report with photos of what we found.
Piston & Gear Garage on Cleveland Avenue writes the work order first, so you see every part and price up front. Same-day check-engine diagnostics, a 36-month warranty, and six ASE-certified technicians.
Tell us the car and the symptom. We reply within 1 business hour.
Thanks. Your work order is in. A service writer will call you shortly.



Every job starts as a written ticket: the part, the labor time, and the price from, stamped once you approve it. Prices shown are starting points before we see your car.
OBD-II scan, road test, and a written report with photos of what we found.
Pads, rotors, calipers, and a fluid flush, followed by a road test.
Full synthetic oil, new filter, and a 21-point safety check every visit.
Mount, balance, and a four-wheel alignment measured against factory spec.
Timing components, gaskets, cooling systems, and full rebuilds.
Fluid exchange, filter, and diagnostics for automatic and manual gearboxes.
Recharge, leak test, blower and compressor repair to hold set temperature.
Starting, charging, alternator, and wiring faults traced to the source.
Nothing gets fixed until you approve a written work order. You see the part, the labor hours, and the price before a wrench turns.
Parts and labor are covered for 36 months or 36,000 miles, whichever comes later, honored at the counter with no fine print.
Every inspection includes photos of what we found, sent to your phone so you decide with the same view we have.
Four loaner cars and a shuttle inside I-270, so a repair does not cost you a day off work.
Six ASE-certified technicians running factory scan tools for more than 30 makes, foreign and domestic.
They found a coolant leak two other shops missed, texted me photos, and had it fixed by 4 that afternoon. The bill matched the estimate to the dollar.

I bring all three family cars here. The 36-month warranty is not a slogan: they covered a wheel bearing 14 months later with no argument.

Dropped off for a brake job, got a loaner, and picked it up the same day. The work order listed every part and the price before they started.

Call, text, or send the work-order form. Most check-engine cars get a written estimate the same day they arrive.
