If you want the maximum performance of your diesel truck, then you need to ensure that your wastegate works properly. When it comes to any automotive part, it helps to understand how it works. When you know how it operates, it lets you troubleshoot issues better and gives you more of a chance to recognize issues before the problem gets any bigger.

Wastegate Basic Function

According to Wikipedia, the basic function of a wastegate is to help regulate the flow of exhaust gases. It allows for correct turbine speed, which impacts your compressor. A wastegate is especially important to turbocharger systems because it helps to control the maximum boost.

Internal and External

The wastegate can be internal or external. Internal wastegates are factory-installed units that will work for the base turbo that comes with your vehicle. If you add a turbocharger to your vehicle, then you will want an external one.

Wastegate Controls

Wastegate controls can be hydraulic, electric, manual, or pneumatic.  Hydraulic controls use the engine oil as the fluid to operate it. An electric model will use electricity to provide power. A manual part will require you to control the position. The pneumatic model uses air compression in operation.

Issues

One of the most common issues you will have with wastegates is a loss of turbo boost. You may also notice the turbo not acting as it should. You may see a decrease in fuel consumption as well. If you have an internal one, your check engine light may come on as it will affect the exhaust system’s ability to perform at peak capacity.

Wrapping Up

The wastegate is something you will find on turbocharged vehicles. If you don’t have a turbo, then you probably don’t have one on your truck. If you experience symptoms of an issue, you should get your wastegate checked for performance issues.
