Source: https://route66autorepairshop.com/service-areas/auto-repair-in-la-puente Updated: 2026-09-17 Business: Route 66 Auto Repair, 1775 W Foothill Blvd, Upland, CA 91786, (909) 608-7699 Hours: Monday to Friday 8 AM–5 PM, Saturday 8 AM–2 PM, Sunday closed **TLDR:** La Puente drivers take the **I-10 east** to us. We diagnose **check engine lights**, leaks and exhaust, and split the estimate into **need-now and later**. Route 66 Auto Repair in Upland helps La Puente drivers keep older, high-mileage cars running without surprises. We diagnose check engine lights, find oil leaks and fix exhaust problems, and the written estimate tells you which repairs are urgent and which can wait. The shop is at 1775 W Foothill Blvd, a drive east on the I-10, so we are not your corner garage, but the process is built for drivers watching every dollar. ## What is the easiest way from La Puente to Foothill Blvd and Central? Most La Puente drivers head north on Azusa Ave or another main north-south street to reach the I-10, then go east. Stay on the I-10 through West Covina, Covina and Pomona to the Central Ave exit. Go north on Central through Montclair until you hit Foothill Blvd in Upland. We are one block east of In-N-Out Burger. From the south side of town, some drivers use the 60 east instead, then the 57 north to the I-10. Either way, freeway traffic sets the pace. The [directions page](https://route66autorepairshop.com/contact/directions) covers the final stretch. ## What does everyday La Puente driving do to an older car? A lot of La Puente driving is short and busy: errands on Valley Blvd and Hacienda Blvd, school runs, and trips across town with a light at every block. Short trips keep engines from fully warming up, which lets moisture build in the oil and wears the exhaust system from the inside. Heavy truck traffic around the industrial areas nearby adds rough pavement and sudden stops. Many families here keep cars for years, and that is smart. High-mileage engines start to seep oil from gaskets, oxygen sensors age, and the check engine light comes on. None of those always means an emergency. The goal is to find out what the light means, fix what matters now, and plan the rest. ## Three repairs La Puente drivers ask us for - **Check engine light diagnosis.** We read the codes with an OBD-II scanner (the port every modern car has), then test the part the code points to, so you do not buy parts on a guess. See [diagnostics and inspections](https://route66autorepairshop.com/diagnostics-and-inspections). - **Oil leaks and oil service.** We find where the oil is coming from and tell you whether it is a drip to watch or a leak to fix. Start with our [oil change services](https://route66autorepairshop.com/oil-change-services). - **Exhaust noise and smell.** A louder car or an exhaust smell in the cabin needs a look. Our [exhaust services](https://route66autorepairshop.com/exhaust-services) page explains what we inspect. ## How do we help La Puente drivers stay on budget? Our phone quotes are ranges, because a price is not real until someone has looked at the car. At the counter, the diagnostic fee is stated before testing, and it applies to approved related repair. The written estimate then labels each line as a safety or strand risk now, or something that can be scheduled. You can fix the urgent item today and plan the rest for a later paycheck. Declined items stay on the repair order, so the next visit starts with a clear list. If you bring your own parts, we inspect them first; labor is still charged at book time, and there is no warranty on a customer-supplied part. AAA members get 10% off parts and labor, up to $75, with the card at time of service. ## Is the drive worth it when shops are closer? La Puente has shops closer than ours, and some of them are good. People who come out to Upland usually want the written, prioritized estimate described above, or they need a Saturday appointment, which we offer from 8 AM to 2 PM. Some are moving and renting a U-Haul truck or trailer from us at the same time. ## What should you do if the car overheats or stalls on the way? Older cars tend to show trouble on the freeway first. If the temperature gauge rises, a warning light flashes, or the car starts to lose power, get to the right lane and off at the next exit if it is safe. If you have to use the shoulder, put your hazards on and stay clear of traffic. Let a hot engine cool before anyone touches the cooling system. Call [(909) 608-7699](tel:+19096087699). We accept tow-ins and will tell you if the board has room. If the car will not start in your driveway, call before paying for a tow, and if it arrives after hours, the key goes in our after-hours key drop. ## Our repair process, step by step 1. **Phone range:** Call with the symptom and get a range. We confirm the board has room before you drive out. 2. **Counter intake:** The diagnostic fee is stated, and we agree on waiting or dropping off. 3. **Codes plus testing:** An ASE-certified technician scans and then tests the actual part before calling it bad. 4. **Prioritized written estimate:** Lines are marked need-now or schedulable, so you choose what to fix today. 5. **Repair, check and road test:** We repair to spec, quality-check and drive the car before handing it back. ## What's included for La Puente drivers - Diagnostic fee stated before testing begins - Code scan followed by a test of the suspect part - Written estimate with urgent and schedulable lines - Photos or the old part when it explains the repair - Declined items saved on the repair order - Road test and written warranty coverage on the invoice ## Is it a need-now or need-later repair? **Need now:** - A flashing check engine light or a car that shakes and loses power - Exhaust smell inside the cabin - Oil dripping onto hot exhaust parts or a low oil warning **Need later:** - A steady check engine light with a car that drives normally, after a scan - A small oil seep with the level holding steady - A slightly louder exhaust with no smell inside ## Frequently asked questions ### How far is Route 66 Auto Repair from La Puente?
