Stop Hidden Fluid Leaks Before They Turn Into Downtime and Engine Damage
If your truck is losing oil, coolant, air, or fuel even slowly, you are already losing money. Leaks rarely fail suddenly; they silently escalate until the truck derates, overheats, or shuts down.
At Salazar Semi-Truck Repair Inc., we locate and eliminate leaks at the source using dealer-level diagnostics, not guesswork or unnecessary parts replacement.
Why Leak Detection Is Not a “Minor Repair”
Most leaks are symptoms, not failures.
A small oil leak can signal:
- Internal pressure imbalance
- Seal degradation
- Crankcase ventilation issues
A coolant or air leak can:
- Trigger derates
- Cause overheating under load
- Lead to roadside shutdowns at the worst moment
Waiting does not “save money.” It multiplies the cost and removes your control.
How We Find the Leak Others Miss
We do not replace parts hoping the leak stops. We diagnose first.
Our leak detection process includes:
- Pressure and vacuum testing
- Thermal and visual tracing
- Electronic sensor validation
- System isolation to confirm root cause
This allows us to:
- Identify the exact failure point
- Prevent repeat leaks
- Protect uptime for owner-operators and fleets
Common Semi-Truck Leaks We Resolve Daily
- Engine oil leaks (seals, gaskets, crankcase issues)
- Coolant leaks (hoses, radiators, EGR, water pumps)
- Air leaks (brake systems, suspension, charge air)
- Fuel leaks (lines, fittings, injector-related issues)
- Power steering and hydraulic leaks
Each one threatens uptime, safety, and profit if ignored.
Who This Service Is For
This service is designed for:
- Owner-operators who cannot afford surprise breakdowns
- Fleet managers protecting schedules and revenue
- Trucks already showing loss, smell, residue, or pressure warnings
If you are looking for the cheapest temporary fix, this is not it. If you want the leak stopped correctly, this is.
Semi Truck Leak Detection FAQs
Small leaks typically escalate under load and heat. Oil, coolant, air, and fuel leaks can trigger derates, overheating, or roadside shutdowns—turning a minor symptom into downtime and expensive secondary damage.
