Turbo tips

Important fitting guidance.

01

Pre-Installation Checks

Before fitting a replacement turbocharger, diagnose the root cause of the previous failure. Check oil quality for contamination, inspect the air intake system, examine the intercooler for debris, and ensure the exhaust system is clear.

02

Important Fitting Advice

Prime the turbocharger with clean oil before startup to protect internal components during initial operation. Check the oil feed and drain lines for restrictions, replace contaminated oil, fit new gaskets and seals, and replace the oil feed pipe where necessary.

03

Installation Mistakes to Avoid

Avoid dry fitting without oil priming, reusing contaminated oil, ignoring blocked DPF issues, and failing to clean the intercooler system thoroughly, as all these steps are essential for protecting the turbocharger and preventing repeat failure.
