Some vehicles are equipped with a turbocharger on internal combustion engines. Its role is to force air into the engine cylinders, increase the quality of the combustion mixture, which leads to an increase in power. The turbine is a very unstable mechanism as it operates at very high temperatures. A common cause of turbine failure is a drop in system pressure.
Necessary
Hoses, adapters and pressure gauge
Instructions
Step 1
Determine the maximum turbine pressure using manufacturer's documentation. If there is no information, then use the Internet and find out the permissible pressure values from the manufacturer.
Step 2
In most cases, the pressure can be measured from the intake manifold. The conclusions on it are closed with special plugs. Or connect the hose to the pressure take-off nipple. Make sure the manifold is connected downstream of the throttle valve.
Step 3
Make sure that the hose does not touch the moving parts of the engine. Pull the hose into the passenger compartment and connect to the pressure gauge.
Step 4
Start the engine. Warm up the engine to the optimum coolant temperature. Take your time during the warm-up process; the engine should warm up gradually. It is advisable to warm up the fluid to operating temperature on the fly.
Step 5
Take a flat stretch of road. Crank the engine to 3000 rpm in 3rd or 4th gear. Maintain the engine speed so that the tachometer value does not exceed 3000 rpm. Use the brake pedal to achieve the result.
Step 6
Depress the fuel pedal all the way and check the pressure gauge. If the pressure readings differ from the documentation, then adjust the turbine or contact a specialized center.
