Auto Repair for Walnut Families and Student Drivers

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 is worth a look.

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.

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.

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. 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.
