2002 XLS Zetec 2.0L I4 engine: Before removing the EGR valve, please note that the Ford workshop manual says the EGR pipe must be replaced if the EGR valve is removed. The pipe & EGR valve are expensive parts, so be sure the problem is w the EGR valve before removing. Although the pipe & etc can be clogged w carbon, it has been reported often that the EGR valve usually doesn't need replacing - typically, EGR problems are with the DPFE sensor.

Also, often times folks report that the EGR valve is hard to remove. So spray the fasteners & big nut w penetrating lubricant (not WD40), let the car sit a while, then drive it somewhere to do something. The next day do it again, let the car cool down a bit, then remove the EGR valve. Use a 10mm socket on the two bolts & a crescent wrench on the nut. To gain better access you may want to remove the air intake duct if necessary.

Note: the torque amount for the EGR valve bolts is 80-INCH/lbs for the bolts on the 2002 XLS 2.0L I4. The big nut is the same: 30 ft/lbs.
