From tune-ups and timing belt replacements to head gaskets and full engine rebuilds — we handle it all with precision and honest pricing.
Schedule AppointmentYour engine is the most complex and most critical system in your vehicle. When something isn't right — whether it's a warning light, a loss of power, an unusual noise, or something you just can't explain — CarTech Automotive has the diagnostic tools and the technical experience to find the problem and fix it correctly.
We service all makes and models, domestic and import, from minor tune-ups and spark plug replacements to major internal repairs like head gaskets, timing belt systems, and complete engine rebuilds. Every repair starts with a thorough diagnosis — we identify the root cause before recommending a solution, and we explain everything clearly before we begin.
Don't wait on engine symptoms. What starts as a small issue can quickly become a much more expensive repair. Bring it in early and let us tell you exactly what's going on.
Common warning signs include a check engine light, loss of power, rough idling, unusual knocking or ticking sounds, excessive oil consumption, white or blue exhaust smoke, and poor fuel economy. Any of these symptoms warrant a diagnostic visit — catching engine issues early almost always saves significant money.
Yes. Timing belt service is one of the most important preventive repairs on your vehicle — a broken timing belt can cause catastrophic engine damage. We follow manufacturer-recommended intervals and replace the belt, tensioner, idler pulleys, and water pump as a complete service.
Yes. For engines with significant internal damage, we assess whether a rebuild or a replacement engine is the more cost-effective solution for your situation. We give you an honest evaluation and a detailed quote before any decision is made — no pressure, no runaround.
It depends on the repair. A tune-up or spark plug replacement is often same-day. Timing belt service typically takes 1–2 days. Major work like head gasket repairs or engine replacement can take 3–7 business days depending on parts and scope. We give you a realistic timeline upfront so you can plan.
We primarily service gasoline engines across all makes and models. If you have a diesel vehicle, give us a call at 615-220-6114 and we can discuss your specific needs and whether we're the right fit.
