1998 Dodge Caravan EGR valve

Usually you'll need a 10mm 6 point socket with a couple short extensions. Spray it up the night before with WD-40 or penetrating oil. Six point sockets and combination wrenches are best for holding the nut without rounding it off.
Don't be worried if you must get a 3/8ths to half inch adapter so you can get more leverage on the nuts or screws. Take off the vacuum lines and get the transducer out of the way and anything else. Having the screws break and come out without breaking them off is the key. Use a propane torch if their stuck. Heat works wonders. ok? Special hint:
have someone else do it.
