How do you change out an EGR valve on a 1997 Nissan pickup 2wd?

You need to take the air cleaner off. Then disconnect the vacuum hose going to your brake booster at the check valve point. There is a valve (EGRC-BRT) next to the EGR remome the the clamp on the braket that is holding the brake booster hose and swing it out of your way. Next you need to remove the vacuum hose from the EGRC-BRT valve and remove the valve nad the bracket that hold the vave. Now you can get to the EGR pipe which attaches to the EGR. Remove the pipe then remove the the bolts that hold the EGR valve.
