We help with first-car maintenance, AC, and a **Deluxe pre-purchase inspection** before you buy used, with a **written estimate** first. Walnut drivers can get to Route 66 Auto Repair by taking the 57 north to the I-10 and heading east to our only shop, at 1775 W Foothill Blvd in Upland. Many Walnut households have a new driver, a first car or a used car purchase coming up. Our ASE-certified technicians handle routine maintenance, AC repair and the Deluxe pre-purchase inspection, and every job starts with a written estimate you approve. ## What is the route from Walnut to Upland? Most Walnut drivers head for the 57 north. From the south side of town that means a short run on the 60 first. The 57 meets the I-10 at the Kellogg interchange in Pomona. Go east on the I-10, exit at Central Ave in Montclair, and turn north. Central takes you up to Foothill Blvd in Upland, and the shop sits there, one block east of In-N-Out Burger. From the north side near Valley Blvd or Temple Ave, you can reach the 57 or the I-10 quickly. On a first trip, the [directions page](https://route66autorepairshop.com/contact/directions) is worth a look. ## What does driving in Walnut ask of a car? Walnut is hilly, with winding residential streets and short, steep climbs. Newer drivers tend to brake late on the way down, which wears pads faster. Many trips are short: school runs, errands, the drive to Mt. SAC and back. Short trips are hard on oil and batteries, because the engine rarely reaches full temperature. Walnut commuters also deal with the 57 and 60 merge in neighboring Diamond Bar, one of the slowest stretches in the region. Summer heat plus crawling traffic tests AC systems and cooling fans. A car that seemed fine in March can blow warm air by July. ## What are three common jobs for Walnut drivers? - **Oil changes and fluid checks for new drivers.** We check oil, coolant, brake fluid and tire pressure, and explain the schedule in plain words. See [oil change services](https://route66autorepairshop.com/oil-change-services). - **AC that stops cooling.** We test pressures and look for leaks before adding the refrigerant your vehicle specifies. Visit [cooling, heating and AC services](https://route66autorepairshop.com/cooling-heating-ac-services). - **A used-car check before you buy.** Our [Deluxe pre-purchase inspection](https://route66autorepairshop.com/diagnostics-and-inspections/pre-purchase-vehicle-inspection) includes a printed checklist, underbody photos, a full-module scan, a road test, a second sign-off and a written buy-or-walk letter. ## What should Walnut parents know about a used-car inspection? The Deluxe inspection is the only one we offer, and every box gets filled. If a box is empty, it is not deluxe. The underbody photos cover the frame, leaks, shrouds and boots. The full-module scan reads stored codes across the car's computers, not just the engine. Another technician or writer signs off, and you get a written buy-or-walk letter. It has honest limits. It cannot promise that nothing will fail later, and it cannot see inside sealed parts. Ask the seller to let you bring the car in, and call ahead so we can plan the time. ## What should a new driver do if the car overheats or will not start? Teach this before it happens. If the temperature gauge climbs or a red light appears, signal, move right, and get off the road where it is safe. On the freeway, that means the next exit or the far right shoulder with hazards on. Turn the engine off and never open a hot radiator cap. Then call [(909) 608-7699](tel:+19096087699). We accept tow-ins, so the car does not need to be driven any farther. If the car will not start in a school lot, tell us whether it clicks, cranks slowly or does nothing. That points us to the battery, the starter or something else. ## How does a Walnut visit work, step by step? 1. **Book a time:** Call so we can check the board. We text you if the time will slip. 2. **Talk it through:** The service writer explains the diagnostic fee before testing. It applies to approved related repair. 3. **Inspect:** An ASE-certified technician tests the car and notes anything a new driver should watch. 4. **Written estimate:** Each line is marked need-now or can-wait, in plain words a new driver can follow. 5. **Repair and road test:** We repair to spec, run a quality check and road-test the car before pickup. ## What's included for Walnut customers - Diagnostic fee explained before testing - Written estimate with need-now and need-later labels - Plain-language notes a new driver can follow - Photos when the part is the point - Quality check and road test - Warranty coverage listed on the invoice ## Can this wait until the semester ends? **Need now:** - Brakes that squeal constantly or grind - A red oil pressure or temperature light - A tire that keeps losing air **Need later:** - AC that is a little weaker than it used to be - An oil change due in the next month - Faded headlight lenses on a car driven mostly by day ## Frequently asked questions ### How far is Route 66 Auto Repair from Walnut?
