Our emissions and exhaust system services include:
- DPF (Diesel Particulate Filter) cleaning and regeneration

Diesel engines generate a lot of heat, especially under load. That’s why proper cooling system maintenance is essential for avoiding overheating and serious engine damage.
We provide:
- Radiator replacement and repair
- Coolant flush and refill
- Water pump and thermostat service
- Hose and gasket inspections
- Fan clutch replacement
If your truck runs hot, leaks coolant, or overheats, bring it to Tune Tech Monroe — we’ll keep your cooling system performing at its best.
