Charge Air Cooler Repair & Aftercooler Repair in St. Louis, MO
Charge Air Cooler Repair
When your charge air cooler (CAC) fails, it can drastically reduce boost pressure, impair airflow, and increase fuel consumption. Our expert charge air cooler repair services restore damaged intercoolers, clean internal contaminants, and patch or replace worn parts that impact heat transfer.
Our St. Louis repair shop handles:
- Pin-hole leaks and cracks using epoxy, jb weld, or professional aluminum welding
- Full pressure tests to detect damage
- TIG and welder-based precision repairs
- Cleaning and re-sealing intake manifold and hoses
- Charge Air Cooler maintenance
Whether it’s a heavy-duty automotive application or a diesel engine powering an industrial system, CAC integrity is crucial. We work on Cummins, Freightliner, Caterpillar, and more.
We also service:
- Damaged heat exchanger components
- Failed aftermarket installs
- Integrated radiator and radiator repair needs
- Condensers and coolant issues
IHT offers fast diagnostics for compressed air inefficiencies and turbo-related failures caused by turbocharger backflow or heat damage.
Aftercooler Repair & Service
An efficient aftercooler prevents high oil temperature, corrosion, and raw water damage in marine and diesel engine systems. Whether you operate 6BTA, 6CTA, QSB, or Cummins Marine engines, we offer professional aftercooler service and cleaning for longevity and efficiency.
Our aftercooler maintenance process includes:
- Internal inspections for salt water, zincs, separator, and contaminant buildup
- Tube bundle checks and gasket, o-ring, and manifolds replacement
- Leak detection using pressure tests
We work closely with OEM specifications or reliable aftermarket components. From air intake cleaning to air compressor and intercooler inspection, we offer complete system support.
