Maintaining a Turbocharger in 5 Simple Steps
We've seen it many times, a customer will drive in with a leaking turbocharger and say it drives great, starts first time when it's cold and gives good boost with no problem - just need the leak fixing.
It's one thing fixing a turbo fault but to ensure it doesn't fail again (or at all if yours hasn't yet) it's worth taking a few moments to understand how to maintain a turbocharger and prolong it's life expectancy.
1. Start + Idle
On a cold start, the oil in the sump pan will be cold + thick and will take longer than usual to flow around the engine and components. Always let the engine idle for a moment (at least 1 minute) before driving away - this will give the oil time to warm up, thin down and make its way to all the components to ensure they are properly lubricated and protected.
2. Regular Oil Changes
Over time your oil will deteriorate and lose it's protective properties. Carbon can mix in with oil overtime and on modern diesels you may have diesel mixing in with the oil which will thin it down more than normal and have the same undesired effect. Be sure to change your engine oil regularly for maximum protection.
3. Regular Air Filter Cleaning / Changing
The turbocharger sucks clean air through the air filter. If your air filter hasn't been changed in a while and is blocked it will create a build up of pressure on the inlet of the turbo and put excessive strain the seals.
4. De-Carbonising Session
Over time carbon residue can build up in the EGR valve, around injector nozzles, in the combustion chamber and inside the turbocharger itself. Carbon build up will make the components work harder and become less efficient. Decarbonising removes the unwanted residue to ensure your components are always working efficiently. Sinspeed offer de-carbonising sessions, contact us for more information on this.
5. Idle + Switch Off
After a long run you should always allow the engine to idle for at least 45 seconds before switching off. Although your engine RPM may be at idle, the turbo will need a bit longer to spool down and if it is not giving this extra time before switching off you may experience a "back-spin" which can ultimately destroy a turbocharger.
The above 5 steps are easy to follow and will definitely help maintain your turbocharger. If your turbocharger is faulty then it is even more reason for you to follow the above 5 steps after having the turbocharger repaired to ensure it doesn't fail again!
