Diagnosing Turbo Boost And Leak Problems
You are probably seeing more turbocharged four-cylinder engines. Domestic manufacturers like GM and Ford have powered a wide variety of cars and SUVs with small displacement turbo engines. Also, import manufacturers like BMW, Nissan and VW use turbos on base engines and high-performance engines. Turbos are not a new trend; many applications have been on the roads for more than a decade.
Don’t Fear The Turbo
The turbocharger gets a bad rap. So many technicians can name reasons why they have failed in the past, yet they can’t recall when or why a turbocharger has failed recently. With more and more vehicles employing a turbocharger to achieve power and fuel efficiency from a downsized engine, the importance of maintenance is more critical than ever.
