Route 66 Auto Repair in Upland, at 1775 W Foothill Blvd, serves Corona drivers who want AC repair, transmission work or a deluxe pre-purchase inspection done with everything in writing. We are a drive north of Corona, and we say that up front. ASE-certified technicians, a diagnostic fee stated before testing, and Saturday hours are why some Corona drivers choose us anyway.
How do Corona drivers reach our Upland shop?
Most Corona drivers take the I-15 north past Norco and Eastvale, over the 60, to the I-10. Head west on the I-10 to the Central Ave exit, then north on Central Ave through Montclair to Foothill Blvd. We are one block east of In-N-Out Burger.
From the west side of Corona, some people go north on the 71 through Chino Hills toward Pomona and pick up the I-10 east instead. Both routes can clog at peak hours. Call before you leave and check the directions page for the last few blocks.
What makes Corona driving hard on AC and transmissions?
Corona is known for its commute. The 91 west toward Orange County is one of the busiest freeways in Southern California, and long stretches of it move in stop-and-go waves. That pattern keeps an automatic transmission shifting and heating its fluid, and it keeps the AC working hard with little airflow across the condenser.
The heat in Corona is serious in summer, and drivers heading south on the I-15 through Temescal Valley add long grades to the mix. Short trips on Main St, Ontario Ave and McKinley St fill in the rest of the week. When an AC system is low or a cooling fan is weak, a traffic jam in August is where it shows.
Three things Corona drivers often come to us for
- AC that blows warm in traffic. We check pressures, look for leaks and test the fan, then recharge with the refrigerant your vehicle specifies once the leak is handled. See cooling, heating and AC services.
- Transmission service and diagnosis. Stop-and-go on the 91 is rough on fluid. We test before recommending anything. See transmission services.
- A deluxe pre-purchase inspection. Printed checklist, underbody photos, full-module scan, road test, second sign-off and a written buy-or-walk letter. See the pre-purchase vehicle inspection.
Why do Corona buyers drive up for a pre-purchase inspection?
Buying a used car is where people most fear a bad surprise. Our pre-purchase inspection has one tier, deluxe, and every box gets filled: the printed checklist, underbody photos of the frame, leaks, shrouds and boots, a full-module scan, a road test, a sign-off by a second technician or writer, and a written buy-or-walk letter. If a box is empty, it is not deluxe.
We are also honest about the limits. An inspection cannot promise that nothing will fail later, and it cannot see inside sealed components. Call ahead so the board can hold the time, and let the seller know where the car is going.
Why do other Corona drivers make the trip?
Corona has many shops, and plenty of drivers are happy with one near home. The ones who come to us usually want Saturday service, which runs from 8 AM to 2 PM, or a written estimate that separates what is urgent from what can wait. Others are renting a U-Haul truck or trailer, and trailer renters get a free hookup check before leaving the lot. Reservations are made on U-Haul (opens in a new tab).
What if the car overheats on the I-15 on the way up?
If the temperature gauge climbs, turn the AC off and get to the right lane. Leave the freeway at the next exit if you can do it safely, and stop somewhere off the road. Shut the engine down and give it time. Never open the radiator cap while the engine is hot.
Then call (909) 608-7699. We accept tow-ins from Corona and will check the board so the car is not waiting in the lot. If it will not start at home, call before arranging the tow. A tow that arrives after hours can use our after-hours key drop.
How your Corona visit is handled
Step 1: Call and book
We check what the board can hold and tell you honestly if today will not work.
Step 2: Intake
The fee is stated at the counter, and we decide together whether you wait or drop off.
Step 3: Inspection and testing
An ASE-certified technician tests the AC, transmission or the whole car for a pre-purchase inspection.

Repairs come as a written estimate with need-now and need-later lines; a pre-purchase inspection ends with a buy-or-walk letter.
Step 5: Repair and road test
Approved work is done to spec, checked, and road-tested before you head back south.
