INSTRUCTIONS FOR REPLACING A TURBO
Experience has shown us that the cause of turbo failure is to be found in the turbo's direct environment. For this reason, it is essential to determine the cause of the failure and correct it before mounting a new turbo, in order to prevent a re-occurrence. If the problem is not corrected identified then, within a short space of time, the turbo is likely to fail again.
When mounting a turbo, the following instruction is essential. Furthermore, failure to comply with any of these instructions could invalidate the warranty.
-
Do not replace the turbo until you know the reason for the deterioration or failure.
-
Inspect the oil inlet and outlet. Pipes and clean if necessary.
-
Inspect the section pipes and engine exhaust gas manifold and clean if necessary. Any foreign body narrowing of the pipe caused by an obstruction could cause damage.
-
Do not apply any type of sealant to the oil inlet and outlet seals.
-
Change the oil filter and replace oil using the correct grade as recommended by vehicle manufacturer's specification prime turbo with oil syringe provided before starting up engine it's very important to ensure that the turbo lubrication is correct since this is one of the principle causes of failure.
-
Check that oil return pipe is straight and that there are no blockages to ensure an adequate oil return.
-
Replace the air filter and check that the hoses are in good condition.
-
Please change all gaskets supplied with the turbo.
-
Once the new turbo has bean mounted start up the engine and leave it idling for a minute. And check the operating pressure with the engine at full load. Leave the engine idling for a few seconds before switching it off ( do not put the engine under any heavy acceleration just before switching off ).
For your safety, you are advised not to touch the turbo whilst it is operating, nor immediately afterwards, given the fact that the turbo could be at a very hight temperature.
POTENTIAL PROBLEM IN TURBOCHARGER
LACK OF POWER
Check that filter, hoses and pipes are clean and in good condition.
Check that the fuel injection system is in good condition and correctly adjusted.
Check that the exhaust system, including catalyst and DPF, is not blocked or not damaged.
NOISY PERFORMANCE
Check that the pipework and support brackets are not loose or damaged and that the connections are good.
Check for any leakages or cracks in inter-cooler.
EXCESSIVE SMOKE OR OIL CONSUMPTION
Check that the air filter are not restricted or blocked.
Check that engine oil specifications strictly correspond to car manufacturer's recommendations.
Check that the oil drain pipe is clean and not restricted.
Check that the engine oil pressure is not excessive and that the motor ventilation system working properly.
Check that hoses and joints are in good condition.
Check for lubrication problems in engine block if oil or carbon deposits are found on exhaust manifold or in the turbine.
