What is the Wastegate Hose all about?

Turbos work on exhaust gas, which regulates the speed of the turbocharger turbine and determines the maximum amount of boost delivered to the engine. The wastegate hose is responsible for diverting gases out of the turbo. However, these hoses are subject to immense heat, which when combined with wear and tear, can eventually deteriorate significantly. Problems with wastegate hoses include leaks, blockages, and more.

Keep in mind:

• Most wastegate hoses are made of rubber or silicone and are susceptible to damage from engine heat.

How it's done:

• The faulty wastegate hose is located and identified
• The wastegate hose is removed
• The new wastegate hose is installed and the hose is connected
• The engine is started and idled, then the new hose is checked for leaks
• The vehicle is road tested and checked for proper operation

Our recommendation:

If you have symptoms of power loss or hear a hissing noise under the hood, a wastegate hose leak is likely at fault. Have one of our expert mechanics diagnose your wastegate hose issue.

How important is this service?

If your wastegate hose is damaged, your engine is not getting the boost it needs from the turbocharger. This compromises performance and can even affect your fuel economy. Don’t wait too long if your wastegate hose needs to be replaced.
