EGR valve

Anyone know where the EGR valve is located on a 2003 Silverado with a 5.3L? Thanks

the EGR should be top, front of the engine right beside the water inlet (thermostat housing) just behind the drive belt

This is what it looks like:

Its easy to replace. make sure the replacement has a new gasket and dont put silicone on it.

Make sure the port(s) isn't (aren't) clogged with carbon.
