This Oil Separator Kit by Steeda fits all 1979-2004 Mustangs.

1. To start the installation of your Mustang Steeda 555-3710 Oil Separator Kit, locate PCV valve on valve cover. It will have a 3/8" rubber hose going to it and will connect to the intake.

2. Carefully remove hose from Mustang PCV valve and intake inlet.

3. Find a suitable location to mount the Steeda separator, usually the firewall or shock tower will be best.
4. Mount the separator using the supplied hardware and measure the distance from separator to PCV and separator to inlet on the intake.
5. Cut the supplied 3/8th hose to the proper lengths and connect from Mustang intake manifold to separator and from separator to PCV valve. Use the supplied hose clamps if anything fits loosely.

6. Double check that all your connections for the Mustang Steeda Oil Separator Kit are tight and start the car.
Tip: To drain oil you can simply unscrew the clear container from the bottom and drain it. For small amounts, there is a pressure release valve on the bottom of the clear container.
