Locals call it San Ann or San An, and the 2020 Census counted 1,297 people inside its limits. Small as it is, San Antonio keeps its own city hall and its own water department, and its 33576 ZIP reaches well past town toward the business parks and county facilities out by I-75. RDI Power serves the city from Brooksville. Our shop is about 24 road miles from the middle of town, and a mobile technician can go to a truck that should stay where it is. Below is a short introduction to the community, the drive, and the San Antonio pages that go deeper on each kind of truck.
San Antonio, or San Ann: the 1882 colony on Lake Jovita
Judge Edmund F. Dunne founded San Antonio in 1882 as a Catholic colony and named it for St. Anthony of Padua. The town sits on the western shore of Lake Jovita, on hilltop ground that runs from about 110 to 183 feet above sea level. St. Anthony of Padua Catholic Church dates to 1883, and Saint Anthony Catholic School, opened in 1884, is the oldest school in Pasco County. San Antonio incorporated in 1891, renamed itself the City of Lake Jovita during the 1926 land boom and switched back in 1931.
City Hall, built in 1939, stands on Pennsylvania Avenue. City Park is where the Jaycees held the first Rattlesnake Roundup on November 4, 1967. The motto, “Gem of the Highlands,” still fits a town set on a hill above its lake. St. Leo, next door, grew from the same Catholic beginnings but is a separate town with its own government, and St. Joseph, a few miles north, calls itself the kumquat capital of the world.
Curley Road to Donto Way: the drive from San Antonio
From central San Antonio our mapping data sends a truck out Curley Road, along St. Joe Road and up Lake Lola Road to Spring Lake Highway (CR-541), then west on SR-50 (Cortez Boulevard) into Brooksville. Count on about 24 road miles and roughly 40 minutes. Nearly all of it is county road, and that matters when a truck is already sick. A diesel that is overheating, losing oil pressure or stuck in reduced power should not attempt the trip. Call first, and we will help you weigh a drive, a tow or a mobile visit.
Trucks that work closer to the interstate have one more option. I-75 Exit 285, at SR 52, lies west of town, and a mobile technician can meet a truck at a yard or job site out that way as easily as on a city street.
Old SR 52, new SR 52 and the San Antonio diesel
For decades SR 52 ran straight through San Antonio. Since 2023 the state road has followed a 4-lane divided realignment south of town, and the old route through the city is now County Road 52. East of I-75 the new road passes an industrial park, cuts through the Mirada development and meets Curley Road just south of the city limits.
Those 2 roads describe 2 very different lives for a diesel. A truck that only makes short runs along County Road 52 and Curley Street rarely gets its exhaust hot for long enough to finish a regeneration, so soot builds in the particulate filter and the EGR system. A truck that heads for the 4-lane and the interstate every day piles up steady miles that wear injectors, turbochargers and cooling systems. The hills around Lake Jovita add load to both, more so with a trailer behind.
Either truck gets the same start: a real diagnosis. Our technicians connect dealer-level software, Ford IDS on Fords and WiTECH on Ram and other Stellantis trucks, test the system the codes point to and confirm the failed part before replacing anything. You see the findings in a digital vehicle inspection, with photos and the technician’s notes, before you approve a repair. Fuel system work uses Bosch and Alliant Power components where they apply. Power Stroke, Duramax, Cummins, Caterpillar, Detroit and Volvo engines in light, medium and heavy duty trucks are all routine here, and the full scope is on our diesel service and repair page.
Labor on a San Antonio repair is backed for 3 years or 36,000 miles, the same as a repair for a Brooksville neighbor. Military members and veterans, police officers and firefighters receive 10% off.
Which San Antonio page fits your truck
Pickup owners will find engine-by-engine faults and advice on the drive in on our San Antonio truck repair page. If the truck cannot move, or it is stopped somewhere along SR 52, mobile diesel repair in San Antonio explains how a technician comes to it. Operators running several units out of the 33576 area can read about RDI Fleet plans on the San Antonio fleet maintenance page, and owners of tractors and heavy straight trucks have a semi truck repair page of their own. Neighbors across the lake can compare notes on diesel repair in St. Leo.
Phone (352) 433-3800 on a weekday between 7:00 AM and 4:00 PM, say what the diesel is doing and where it is parked, and we will lay out the plan from there.
