General part question
#4
On my 2001 there is the A.I.R. pump and solenoid/valve down low right next to the idler arm, between it and the oil filter adapter. On mine there is one vacuum line to the electrical solenoid, then a line from the electrical solenoid to the vacuum operated valve. I just replaced mine a couple of months ago and the AC Delco replacement kit relocates the A.I.R. pump inlet and the electrical solenoid to up high next to the top of the radiator in order to keep moisture out (and subsequently locking up the pump). There was a tech bulletin on it. Not sure if 2000 has the same A.I.R. system though...... Do you have the check valves at the front of each exhaust manifold? If so, I bet it's the A.I.R. system in some form. My pump/solenoid/valves were 2001 only.
OK I looked it up and yours should be similar to mine.
Here's the diverter valve
