Installation/Fitting Tips


Recommended Posts

1. Why turbos fail? – Diagnosis

Investigate cause of original turbo failure before fitting replacement

Most turbo failures are due to – Oil Starvation/Contamination, Electronics sensors, Air leaks over speeding turbo, or foreign matter entering compressor housing. Breather problems.

2. Rectify Malfunction

Upon completion of diagnosis and conclusion of malfunction or component failure, either you must rectify the malfunction or replace the failed components with new components. Check for foreign particles. All BEFORE you fit the new turbo.

3. Replace Components

Before fitting your new Turbo, you must Replace Components listed below

OIL FEED PIPE (from engine to top of turbo), replace banjo bolts and oil drain

Replace Turbo oil drain hose (check clear / check no damage to pipe)


Oil and oil filter (correct grade as per manufacturers recommendation)

Air filter

Gaskets and washers, O rings

Diesel Particulate Filter liquid level sensor topped up with fluid level

4. Clean or Replace

Diesel Injectors – Clean, Test, Replace

Air box and air intake hose to turbo (Pressure Test)

Oil cooler/ intercooler/ hose, from turbo to intercooler (damage or air leak). Get Pressure Tested

E.G.R VALVE – Check correct operation, clean or replace if necessary

Breather system, cam cover (rocker cover) – check for blockage

Clean Inlet/exhaust manifolds, check for carbon deposits/cracks/clean head faces/replace gaskets

Ensure the exhaust and/or catalytic converter/diesel particulate filter (DPF) are not fully or partly blocked

Before fitting Turbo – check no debris enters turbo, check all gaskets fit with gas tight seal

Flush Engine

5. Fit and Test Turbo

Check OIL PRESSURE is within manufacturers Tolerances

Start engine and allow to idle for 3-5 mins before driving (do not let engine idle unnecessarily)

Check for Oil/Gasket/Air Leaks, All OBVIOUS locations on engine

Plug into diagnostic machine to check for any fault codes (rectify or repair as per diagnosis, before road test).

A professional mechanic or turbo tuning shop is only recommended for the turbo fitting job of your car. The external influence on the failure of the turbo is not included in the warranty. And only with the turbo properly fitted, you will have your car return to the road earlier.
