TurboDirect SA the official agents for Borg Warner and Garrett turbocharges, the original factory-installed turbo that was originally firstfitted to your brand-newvehicle. It can nowbe replaced at 50% less than the manufacturer/vehicle agentwill charge you.
“Turbochargers are critical components to an engine’s reliable operation, correct emission production, and under bonnet thermal management. The turbocharger, although situated outside the engine, is fed the same oil as the engine from the very engines oil pump. The oil is fed through an oil feed line, which is the main “artery” feeding the life blood to the turbocharger,” said Chris Kambouris founder, owner and MD of TurboDirect SA
When an engine fails for example the entire engine is disassembled, and checked for the cause of failure, this failure mechanism is resolved/replaced, and then the engine is reassembled. Most engine rebuilds involve a new oil pump – being the main cause ofmany engine failures, besides wear components(rings, pistons,valve seats, valve stem seals etc.) these are relatively affordable components normally ensuring a new life span of the engine.
When a turbocharger fails, because it is situated outside of the engine, it is normally treated as an alternator or start motor, and removed, replaced or repaired, and re-installed. The vehicle owner normally expects a newly replaced turbocharger to have had its life renewed and expects to see another 150 to 200 000 kms of service from the new turbo. This is not how it works; the turbocharger is a component that operates at enormous rotational speeds, often in excess of 120 000 rpm and operates at temperatures above 650 deg C in normal operating conditions. The latest Euro 5/6 engines turbochargers are manufactured with exotic materials and operate above 850 Deg C
Just because the turbocharger is physically installed outside of the engine, when it fails, it is imperative to treat it as if you were treating an engine rebuild – the most important step to ensuring a renewed service life from a turbocharger that is being replaced is to firstly find the cause of failure, correct this mechanism/component, and then repair/replace the turbocharger and re-install according to the turbo manufacturers procedures and guidelines.
A turbocharger is an extremely reliable component, it will normally last as long as your vehicles engines life, the manufacturers design turbochargers to exceed 300 000 km’s in terms of service in a single lifecycle, however many turbochargers don’t see this, due to engine maintenance related issues. Lack of maintenance, late maintenance, incomplete maintenance,whichwill all shorten the life of your turbocharger. Correct, timeous maintenance will prolongthe life of your turbocharger. There are 4 main “killers” of turbochargers which can easily be addressed and managed in order to protect and prolong your turbochargers life, these are never mentioned to you by any vehicle manufacturers, or garages. Most mechanics aren’t even aware of this information.
The following are the 4 “big killers” of Turbo Chargers: –
- Lack of lubrication (oil starvation)
- Oil contamination (many different types of contamination exist)
- Foreign object damage (Debris impact)
- Exceptional operating conditions (Often related to intentional changes)
Recommended Turbocharger Maintenance tips from TurboDirect SA:
- Service your vehicle on time, every time.
- Use only genuine parts including oil filters, air filters and the correct grade of oil (check the owner’s manual for this, there is a very specific reason for this)
- Allow the engine to idle for a short while to stabilize temperatures before shutting off the engine or drive the last few km’s of your journey slowly, “off boost” to allow air flow to start to cool down the engine and turbo before you arrive at your destination.
- Replace the oil feed line at specific intervals depending on the vehicle make and application – information available from TurboDirect S.A
- When replacing a turbocharger always replace the oil feed line, oil, oil filter and air filter, regardless of mileage, or oil condition.
- Regularly check the operation of the PCV valve and DPF as well as the EGR valve in your car, as these have a direct effect on the reliable operation of the turbocharger.
- If your vehicle has a worn engine (blow by past the rings) your turbocharger will give you problems.
- Make sure the engines breathers are not blocked, a blocked breather will cause a turbocharger to “leak oil” and smoke.
