How to Choose a Diesel Turbocharger
Share
The short answer: a diesel turbocharger is matched to a specific engine, so the right one depends on your engine code and the part number of the unit you are replacing, not just the vehicle's make and model.
What does a turbocharger do?
A turbocharger uses exhaust gas to spin a turbine, which drives a compressor that pushes extra air into the engine. More air means the engine can burn more fuel efficiently, giving more power from the same engine size.
What are the signs of a failing turbocharger?
- Loss of power or slow acceleration
- Blue or grey smoke from the exhaust
- A whining, whistling or siren-like noise that was not there before
- Oil leaking around the turbo or in the intake pipes
- Engine warning light or limp mode
These signs can also come from other faults, such as a blocked filter, a boost leak or a fuel problem. A workshop should diagnose the cause before a turbo is replaced.
Why do turbochargers fail?
Most turbochargers fail because of something around them: oil starvation, dirty or degraded oil, a blocked or restricted oil feed or drain line, foreign objects in the intake or exhaust, restricted airflow, cooling problems or very high exhaust temperatures. If the cause is not found and fixed, a new turbo can fail the same way.
What do I need to have ready when I order?
- Vehicle make, model and year
- Engine code
- The part number on the turbo you are replacing (often on a plate or stamped on the housing)
- Whether the turbo is for a car, bakkie or truck
If you send these to us, we'll help confirm the correct part when the vehicle details are provided and this is requested.
Should I buy a new or remanufactured turbo?
Some turbochargers are available both as new units and as remanufactured units. A remanufactured turbo is a used unit rebuilt to specification, usually at a lower price. Read our guide to reman vs new diesel parts for what to look for.
Who should install a turbocharger?
Diesel Fuel Parts supplies parts only and does not offer fitment. Fitting a turbocharger correctly involves inspecting the oil feed and drain lines (and replacing them if they are blocked or contaminated), cleaning the mounting surfaces, using the correct gaskets and hardware, priming the unit with oil, and checking for leaks afterwards. Mistakes here can damage a new turbo within minutes of starting the engine. We always recommend professional installation so the new part is not compromised in any way.
