A blow off valve is a Slogan that allows recirculating air to Way out the intake/exhaust action on a turbocharged vehicle. Installing a blow off valve gives the air a levy to force and relieves force from the turbo's compression wheel during gear shifts (when the Chauffeur's foot is off the accelerator).
Instructions
1. Without the blow off valve, air would be forced back into the turbocharger's compression wheel when the Chauffeur's foot is taken off the accelerator, causing undue stress on the turbo's components. This, in turn, slows turbo spool up date. Over continuance, this could create the turbo to fail.
Unfastened the hood and disconnect the rejection cable from the battery terminal. Disconnect the positive cable from the battery terminal.
2. Remove the battery.
3. Locate the factory recirculating valve. Use your shop manual if you need a visual description for the valve specific to your vehicle. This valve recirculates the intake air to the exhaust. This is the device we want to replace. There will be two hoses connected to vacuum lines. The top vacuum line is connected to the throttle body after the intake. This vacuum pressure is what makes the valve operate.
4. Use either a screwdriver or socket wrench (either should work) to remove the screw bolts on the hose clamps.
5. Slide the hose clamps out of the way and use the screwdriver to pry both the vacuum lines off.
6. Install the new blow off valve. Install the hoses the opposite way of removal.
7. Put the batter back in and reconnect the positive cable to the battery first, then the negative cable.
