Route 66 Auto Repair serves Fontana drivers from our Upland shop at 1775 W Foothill Blvd, west of Fontana on the same old Route 66. We work on gas and diesel trucks and cars, with a focus for Fontana customers on cooling, transmission and towing-related repairs. It is a drive west, not a corner shop, but ASE-certified technicians, a written estimate before extra work and Saturday hours make the trip worth it for many.

How do Fontana drivers reach Foothill Blvd and Central Ave?

The 210 west is the most common choice. Get on at Sierra Ave or Citrus Ave, pass through Rancho Cucamonga into Upland, and exit at Mountain Ave. Go south to Foothill Blvd and turn west. Central Ave is the cross street, and In-N-Out Burger is one block west of us.

Historic Route 66 itself is the other option. It carries Historic Route 66 straight west from Fontana through Rancho Cucamonga to our front door, with no freeway at all. It has many signals, so it is slower, but some drivers prefer it with a tired truck or a car that is running warm. From south Fontana, the I-10 west to the Central Ave exit, then north on Central, also works. The directions page has the details.

Why are Fontana conditions so hard on cooling systems and transmissions?

Fontana sits farther inland than most of our cities, and summer afternoons run hot. Heat is the enemy of coolant, transmission fluid and batteries. Add the truck traffic around the I-10 and I-15 warehouse corridors, and a lot of Fontana driving happens in slow, hot traffic surrounded by big rigs.

Many Fontana drivers also head north on the I-15 through the Cajon Pass toward the High Desert. That long climb is a classic place for an engine to overheat or a transmission to run hot, especially when towing. On the way back down, brakes take the load. Dust blowing off open land and construction sites finishes the picture by clogging air filters.

Which three jobs Fontana drivers bring us most

  • Diesel pickup service. Diesels are welcome, from fuel filters to diagnosis of hard starts and low power. See diesel engine services.
  • Radiator, fan and AC work. Inland heat and Cajon Pass climbs find weak cooling parts. Our cooling, heating and AC services cover testing and repair, using the refrigerant your vehicle specifies.
  • Transmission checks for towing. Hot fluid, slipping on grades and harsh shifts. Our transmission services page explains how we test before recommending work.

Why do Fontana drivers come to an Upland shop?

Fontana has plenty of shops, and some of them may be a fine fit for you. The Fontana drivers who come west to us usually want a clear process. They get a diagnostic fee stated at the counter, a written estimate that separates need-now from need-later, and a phone call before any extra work. Declined items stay on the repair order, so you have a record when you are ready to schedule them.

Towing is another reason. As a U-Haul Neighborhood Dealer, we rent trucks and trailers, and the free towing inspection checks your hookup: coupler and ball size, pin, crossed chains, lights, and tongue weight and hitch rating against U-Haul requirements. If you want your own truck's brakes, tires, cooling and transmission checked before a trip over the pass, that is a normal paid inspection. Confirm current capacity for any rental on U-Haul (opens in a new tab).

What if the truck overheats or will not start on the way over?

If the gauge climbs on the 210, get off at the next exit and find a safe place to stop. Pull into a parking lot rather than stopping in a traffic lane. Turn the engine off, open nothing on the cooling system while it is hot, and call (909) 608-7699.

We accept tow-ins, including pickups. Tell us about any trailer or load so we can plan. If the truck will not start at home in Fontana, call before you order the tow, and if it arrives after we close, the key goes in our after-hours key drop.

How a Fontana repair visit works

  1. Step 1: Call with the details

    Tell us gas or diesel, what it is doing, and whether you tow. We check the board before you drive.

  2. Step 2: Intake and fee

    The service writer states the diagnostic fee and records wait or drop-off.

  3. Step 3: Testing

    An ASE-certified technician tests the cooling system, transmission or diesel fuel system as needed.

  4. Step 4: Written estimate

    Each line is marked safety or strand risk now, or schedulable. You approve before we continue.

  5. Step 5: Repair and road test

    We repair to spec, quality-check, and road-test under real load when the complaint calls for it.
