Signs Your Car Needs Some Care
Not sure if it’s a quick DIY fix or time for a mechanic? Book an inspection if you notice any of these:
- A check engine, brake or battery warning light
- Squealing, grinding, knocking or clunking noises
- Fluid spots under the car: oil, coolant or transmission fluid
- The car pulls, vibrates or the steering feels loose
- Rough shifting, hard starts or loss of power
- Warm air from the AC or a burning smell
- Worse fuel economy than usual

More ways we can help
Beyond the services above, our West Valley technicians handle the everyday work that keeps a vehicle reliable:
- Batteries, belts and hoses: tested and replaced before Utah’s cold mornings and hot summers find the weak spot.
- Fluid services: coolant, brake, power steering and differential fluid changed on your manufacturer’s schedule.
- Same-day work: oil changes, brake jobs, diagnostics and alignments are often done the same day. Call ahead to check availability.
How Often Should You Get Auto Maintenance?
Most vehicles benefit from routine maintenance every 5,000–7,500 miles, depending on your manufacturer and how you drive. Stop-and-go traffic on 3500 South, short trips, towing and Utah’s hot, dry summers and cold winters all count as hard use. Follow your owner’s manual, and use this as a guide for the most common services:
| Service | Typical interval |
|---|---|
| Oil change | 3,000–7,500 miles depending on oil type |
| Tire rotation | Every 5,000–8,000 miles |
| Brake inspection | Every 10,000–15,000 miles or once a year |
| Alignment check | Yearly and with new tires |
| Tune-up | Every 30,000 miles or three years |
| Transmission fluid | Every 30,000–60,000 miles |
| AC check | Every 1–2 years, before summer |
Stop by any time and we’ll put together a maintenance plan for your vehicle.

What Auto Repair Costs at Master AutoTech West Valley
We don’t guess at prices. We inspect first, explain what we find and give you an estimate before any work starts, so you approve the cost up front. The check engine light scan is free, and you can request an estimate online. What drives the price is the part that failed, the labor to reach it, your vehicle and the parts grade you choose. Routine maintenance is priced as packages, starting with ProCare oil service at $79.95.

Hear from Our Customers
“I’ve brought in two vehicles in the last week. The first is my business van for which they tested the catalytic converters and found one to be completely blocked off. After replacement the engine breathes like it should and pulls stronger than I ever remember it being. My second vehicle is a 2002 Toyota Camry. Rather than replace the catalytic converter they were able to perform a repair to the flex portion of the catalytic converter assembly for only $147! Thank you Brent!”
Doug M.
“Both Brent and Jacob provide phenomenal customer service. They are so personable and just seem to be genuinely caring people. I took my car in for the advertised $80 A/C service and drove away with cool air. A couple weeks later, it stopped working and Brent offered to do the service again, not only at no cost but taking the car overnight for a more thorough service. They found a problem with the A/C hose and worked to replace it quickly, efficiently and for a fair, honest price. Upon picking up the car again, we actually ended up leaving our 2nd vehicle with them to be looked at for other issues because we felt so comfortable and trusting in this shop! We’re so appreciative of the good service so far and plan on calling these guys up whenever we need more work done.”
Kaesie S.
“They did good and honest work exchanging the exhaust manifold. My car sounds brand new! The mechanic called a few days after and wanted to make sure there were no issues. Exceptional service from exceptional folks.”
