Remove the old turbocharger from the vehicle's engine. This step will involve disconnecting the oil and coolant passages, the exhaust pipes, and any electrical components. Remove the compressor and turbine housings. Remove the old CHRA cartridge from the center of the turbocharger by removing the clips and bolts holding it in place. Clean and inspect the components for any damage. Place the new turbo cartridge and secure it with the clips and bolts. Reconnect all of the oil and coolant lines, exhaust and intake pipes, and electrical connections. Double-check that the turbocharger is installed correctly before starting the engine.
