Installation Notes and Tips

Before installing K1030163N, change the engine oil and filter and follow the included installation guide. Inspect the intake and exhaust tract for contamination, and replace the air filter if needed to reduce the risk of blade damage from debris. Diagnose and correct the original cause of failure before putting the new turbocharger into service.

Allow the engine to cool before shutdown to reduce the chance of oil coking in the turbocharger. Regular oil changes are important, since contaminated or old oil is a common cause of turbo failure. If the wheels or shaft show excessive play, or if there are nicks, scratches, or chips on the wheels, inspect the engine and air system carefully before replacement.
