Radiator Repair
Our radiator repair service addresses leaks, cracks, and corrosion in automotive, truck, and industrial cooling systems. Using advanced welding techniques and premium replacement cores, we restore radiators to original specifications while maintaining structural integrity. The process preserves existing tanks and brackets, significantly reducing costs compared to full replacements. With 24-48 hour turnaround times and a 1-year warranty on new components, this service ensures reliable temperature regulation for vehicles and equipment across multiple industries.
Fuel Tank Welding
Specialized fuel tank welding repairs address leaks and structural damage in aluminum, steel, and stainless steel tanks. Our technicians use Heliarc welding and other precision techniques to restore integrity while maintaining original dimensions. The service includes cleaning, rust removal, and custom modifications like re-strapping or resizing. This cost-effective solution extends tank lifespan by up to 10 years, with repairs completed faster than sourcing new units from traditional dealerships.
Charge Air Cooler Repair
We repair and rebuild charge air coolers that regulate turbocharged engine temperatures. Our process includes leak detection, core replacement, and performance testing to restore optimal cooling efficiency. By maintaining proper air intake temperatures, this service improves engine power output and fuel economy while reducing wear on critical components. The 24-hour turnaround minimizes downtime for commercial fleets and industrial operations.
