How are Turbocharger Intercooler Tube issues diagnosed?
Diagnosing a failed intercooler tube, as well as any boost leak, requires testing the boost piping from the turbocharger to the intake manifold. The means the system must be disconnected from both, plugged at one end, and pressurized at the other like a leak-down test. Otherwise, fractures or other damage to the intercooler tube and intercooler tube seals are noticed upon physical inspection.
How are Turbocharger Intercooler Tubes replaced?
Replacing the intercooler tube requires it be detached from the throttle body and intercooler piping or intercooler. This may be a tedious task, but for longitudinal engines it should be quick and easy. In some vehicles, the radiator fans may need to be removed to extract the intercooler tube.
RepairPal Recommendations for Turbocharger Intercooler Tube issues
RepairPal recommends the entire turbocharger system is pressure tested before any portion is declared faulty. If there is no leak evident in the intercooler and intercooler piping, replacing parts is not a good way to find a leak. Remember, there are many locations on a turbocharged engine that can cause a boost leak.
What to look out for when dealing with Turbocharger Intercooler Tube issues
Even a failed turbocharger can mimic conditions caused by a failed intercooler tube, and the tube is one of the least likely components to fail in the turbocharging system. Also, anytime an underboost situation exists, it is important to test the boost pressure sensor to ensure it is functioning properly.
Can I replace the Turbocharger Intercooler Tube myself?
Anyone can diagnose and replace the intercooler tube. Physical inspection is needed, so the intercooler tube should be removed for inspection, but every component that carries boost pressure from the turbocharger to the throttle body connections should be tested. The tool to test these pipes and the intercooler can be purchased or made fairly cheaply. If a leak cannot be found, have a professional diagnose the issue.
