The EGR valve on a 2002 Galant is located about 4 inches under the intake manifold (black pipes) that are near the back firewall (close to the dash) dead center. It looks like a mushroom with two big hoses and one little hose attached to it. It is connected to the engine by two bolts (14mm I think).
First take out the two bolts and set them aside, careful not to lose the washers on them. There will be a metal gasket that rests in between valve and the engine. Get a replacement at the auto parts store $4 . Then disconnect the hose clamps that hold the hoses onto the EGR valve itself using a pair of pliers. When you are at the parts store get a set of screw down metal hose clamps to save yourself allot of stress and time, for when you put the hoses back on the new valve, $3. The hoses probably have some built up carbon on them and will need a small dose of WD40 to be able to slide off. BEWARE! the EGR valve does have coolant running to it to cool off all those hot gases it controls, so some will leak out after disconnecting hose. This is normal. Then just pull the small hose of the base of the valve. A new EGR valve for the 4 cyl. should cost about $65, $90 or so for 6 cyl. Remember which big hose went to which valve stem. Should be easy. One of the hoses is longer than the other, or just mark one of them. Attach the new valve to the engine, with the new gasket in between them. Don't over tighten the bolts there Hercules, just nice and really snug. Using your handy-dandy new hose clamps ( your welcome ) to reconnect the hose to their correct valve stem. Add back the coolant that you lost during disconnection of the hoses. Then simply disconnect the battery cables for about 5 mins to clear the code that triggers the check engine light. This would be a good time to check the air filter to see if you need to replace it or clean your K&N filter if you have one. Then drive it for about 20-30 miles to allow the engine to cycle through its system checks. If the light doesn't come back on, your good to go.
