Then, attach the fresh oil lines to supply oil from the engine to the turbo. Use a wrench or pliers to screw these lines firmly, ensuring no oil leaks onto the engine. Secure the wastegate actuator rod to link the wastegate to the turbo. Use the nuts or bolts removed before to attach this rod, ensuring it works properly to control the speed of the turbo. Finally, reconnect the air intake duct linking the air TB to the rest of the engine. Use the clamps or screws detached earlier to attach this duct, ensuring a tight fit to transport air into the engine from the turbocharger.
Check for leaks and test the new turbocharger
Inspect all connections made to ensure there are no oil or air leaks. Carefully look for damp spots or signs of oil seeping from the newly attached lines. Air leaks can disrupt the proper functioning of the turbo, leading to decreased performance. If any leaks are found, tighten the corresponding fittings or replace faulty gaskets. Once sure the connections are secure, start the engine and allow it to idle for a few minutes. Rev the engine gently and listen for any unusual noises coming from the turbo. Test driving the vehicle ensures the new turbo works properly. Take it for a short drive and monitor its performance. Pay attention to how the car accelerates and observe the turbo gauge, if available. The new turbo should enhance acceleration and overall power.
Reassemble and clean up
Reattach any other parts detached during the process, such as the air intake system, exhaust components, or heat shields. Safeguard all nuts, bolts, and other fittings used throughout the replacement. Dispose of any old parts, such as gaskets or seals, in accordance with local regulations. Clean up the work area, removing any tools, rags, or debris.
