Installation Notes and Tips

Before replacing the turbocharger, diagnose and correct the original failure cause to protect the new unit. Replace the engine oil and filter during turbocharger service, and follow the installation guide closely to avoid warranty issues. Clean the air and exhaust system, and inspect the air filter so contaminants do not damage the turbo wheels. Allow the engine to cool before shutdown to reduce the risk of oil coking in a hot turbocharger.
