GCL Diesel has an exceptional turbo repair department.

It is important to accept that not all turbochargers are repairable. Many might claim this not to be the case but the risk in repairing turbochargers far outweighs any price advantage gained.

Turbochargers such as the BorgWarner VGT (Variable Turbine Technology), Holset VGT (Variable Geometry Turbocharger), Garrett VNT (Variable Nozzle Turbine), and IHI VG (Variable Geometry) have highly complex design which make it very difficult to remanufacture with any degree of reliability due to the major manufacturers not providing component parts to the aftermarket. Our turbo repair and remanufacture program is specifically for those turbochargers that are repairable.

Because we remanufacture to the same quality, standards, and specifications of the original equipment turbo, you can be confident that our customer repair or exchange turbocharger will meet or exceed original equipment standards.
