Frequently Asked Questions
The check engine light indicates a problem with your engine, emissions system, or sensors. Common causes include loose gas cap, oxygen sensor failure, catalytic converter problems, or misfires. We use diagnostic equipment to read the trouble codes and identify the exact problem.
Common causes include low coolant, thermostat failure, water pump failure, radiator problems, cooling fan issues, or head gasket failure. Overheating can cause serious engine damage if not addressed immediately. Pull over safely and call us if your engine overheats.
Most manufacturers recommend timing belt replacement between 60,000 and 100,000 miles. Check your owner's manual for specific intervals. Timing belt failure can cause severe engine damage, so replacement at recommended intervals is critical.
Blue smoke indicates your engine is burning oil due to worn piston rings, valve seals, or other internal wear. This requires diagnosis to determine the source and extent of the problem.
The decision depends on the extent of damage, cost of repair versus replacement, vehicle value, and your plans for the vehicle. We provide honest recommendations based on your specific situation to help you make the best decision.
Simple repairs like spark plugs or sensors may take a few hours. Major repairs like timing belts or head gaskets typically take 1 to 2 days. Engine rebuilds or replacements can take several days depending on parts availability.
