St. Leo is a college town. The 2020 Census counted 2,362 residents with a median age of 20.3, on rolling hills that rise from about 100 to 187 feet above sea level beside Lake Jovita. A college town still has diesels that need a real shop, and RDI Power serves St. Leo from Brooksville, with a shop about 25 road miles away and mobile technicians for trucks that cannot or should not make the trip. Here is what to know about the town, the drive and the St. Leo pages that cover each kind of truck.
St. Leo, from Benedictine abbey to college town
Benedictine monks founded Saint Leo Abbey and St. Leo College on June 4, 1889, on what had been Judge Edmund F. Dunne’s homestead by Lake Jovita. The town incorporated on the same date 2 years later. The college grew into Saint Leo University, and its 186-acre University Campus, addressed at 33701 County Road 52, lists more than 3,000 students on campus. The Abbey Golf Course sits across the road from the university’s main entrance, and the abbey grounds form a historic district on the National Register.
San Antonio, next door, shares the same beginnings, but St. Leo is its own town with its own ZIP code, 33574. Some addresses inside the town limits fall in San Antonio’s 33576 or Dade City’s 33525 instead, which can be confusing on a service call. All 3 work for us.
From St. Leo’s County Road 52 to Donto Way
County Road 52, the old SR 52, is St. Leo’s main street and the university’s address road. Our mapping data routes a truck from the middle of town west along it, then up Curley Road, St. Joe Road and Lake Lola Road to Spring Lake Highway (CR-541) and finally SR-50 into Brooksville. That works out to about 25 road miles and 42 minutes.
Coming from the interstate is simpler still. Saint Leo University tells visitors to leave I-75 at Exit 285, head east on SR 52 for about 1.2 miles and then follow County Road 52 about 2.4 miles to the roundabout at College Avenue and Pompanic Street. A mobile technician uses the same directions in reverse when a truck has stopped in town.
What St. Leo’s hills ask of a diesel
Florida is mostly flat, and St. Leo is an exception worth noticing from the driver’s seat. Rolling ground means loaded climbs, and climbs are where a diesel’s cooling system, transmission and turbocharger work hardest. A truck pulling a trailer up those grades every day puts more heat into its coolant and transmission fluid than the same truck cruising level highway, and brakes do more work on the way back down. If the temperature gauge sits higher than it used to on the same load, treat it as an early warning, not a quirk.
Highway trucks have a different list. SR 52 now runs as a 4-lane divided road south of town, which makes I-75 a short hop, and trucks that make that run daily pile up the steady miles that wear injectors, fuel pumps and turbochargers. Trucks that only make short trips around town have the opposite problem: their particulate filters rarely get hot enough, for long enough, to finish cleaning themselves.
Whatever the pattern, the repair starts the same way. We scan with dealer-level software, including Ford IDS and WiTECH, test the system the codes point to and find the root cause before a part is ordered. A digital vehicle inspection with photos and technician notes shows you what we found before you approve the work. Our technicians handle Power Stroke, Duramax, Cummins, Caterpillar, Detroit and Volvo engines in light, medium and heavy duty trucks, and RDI Power is Caterpillar certified. See diesel service and repair for the full list.
St. Leo customers get the same backing as everyone else: a 3-year, 36,000-mile labor warranty, and 10% off for active military, veterans, police and fire.
Picking the St. Leo page for your truck
Pickup owners should start with truck repair in St. Leo, which looks at heat, towing and the trip to Brooksville. If the truck has stopped and should stay put, mobile diesel repair in St. Leo explains how a technician reaches it. Separate St. Leo pages cover tractors and heavy trucks on SR 52 and RDI Fleet plans for operations with several units. Our San Antonio diesel repair page tells the story of the town across the lake.
When the diesel is acting up, call (352) 433-3800, Monday to Friday from 7:00 AM to 4:00 PM, and describe the symptom and where the truck is sitting.
