Install Guide
Turbocharger Installation Best Practices
Proper installation helps prevent premature turbocharger failure. Inspect the oil, air, coolant, intake, and exhaust systems to make sure the new turbocharger has clean oil flow, proper airflow, and no restrictions or leaks.
Change Engine Oil & Oil Filter
Fresh oil and a new filter are required for every turbo installation.
Inspect or Replace Engine Air Filter & Intake Ducting
Make sure the intake system is clean and free of debris or restriction.
Inspect Oil Feed Line & Drain Line
Restricted, clogged, or contaminated oil lines can cause
premature turbo failure.
Inspect any Applicable Coolant Lines
Water-cooled turbos require clean, unrestricted, leak-free coolant lines.
Check Intercooler & Exhaust Systems
Inspect hoses, clamps, intercooler piping, exhaust leaks,
and foreign object damage. Oil residue in the intercooler
or exhaust can indicate significant engine issues.
Prime Turbo Before Startup
Pre-lube the turbocharger and verify oil flow before normal
engine operation.
Important:
Always follow the vehicle manufacturer’s service procedures.
A replacement turbo can fail early if the original cause of failure
is not corrected. Undiagnosed engine issues can lead to denied
warranty claims.
