One will be the PCV valve that hooks up dead center rear of the intake upper the other goes to the driver end of the valve cover. Intake manifold changers with little experience dont know wher they go sure will sqeel and idel fast with thes inportant hoses off the other hose if I'm wrong on the vale cover hose is the one going to the brake booster it ges right next to the throttle body on a big port sticking towards the back of the car on the drivers end of the intake

Dear friend-if one of the two hoses got a valve on the one end that must go to the booster and the other will go to the crankcase to **** the gasses from the crank case.

Fuel line diagram for 2004 ford explorer sport trac

It runs from the tank to the frame(drivers side) up to the engine. I don't and you should splice fuel lines. I replace all of it. Plastic or metal. If the leak is coming around the sides of the tank, this could be the fuel sending unit.

I have a 2007 Ford Explorer Sport Trac Limited and the back window is stuck in the down is -17 where I live......The motor is running but maybe window is off the track......Any help would...

You most likely will need to replace the whole track assembly. It is fairly easy to do, however getting to it is the chore. A new assembly runs around $100. The new design is a better design, and it runs quieter.

My drivers side electric window stop working 2002 ford sport trac. how do you change the motor

To remove the door panel, phillips head door screws should be removed, and the panel should slide up. Next, unbolt the window from the regulator and remove the window from the door. Then unbolt the regulator. The regulator and the motor have to be removed together. The motor will be mounted to the door on the inside. There should be three screws or nuts (10mm) holding the motor in. Remove motor and regulator. Reverse to reinstall.
