The thermstat is in the housing at the motor end of the upper rad hose. Two bolts hold it on. The EGR is on top of the intake manifold near the throttle body. It has a vacuum hose and two bolts. If I remember correctly the bolt are inverted torks. Which require a special tool to remove. Use a pair of locking plyers to remove, then replace bolts with standard ones.
