Removing Air Pump

QuantumMotorsports · 06-22-2001, 12:23 AM

EGR and the thermactor air pump are completely seperate! You do not need to disconnect the EGR lines!!! EGR works like this: There is a port in any late model heads that allows exhaust gas to travel up the center of the intake manifold (if you take off your EGR plate you will find there is a hollow place outside of the main port in the intake. The EGR valve opens and closes an opening between the outside of the intake and the inside. The thermactor only injects fresh air into the exhaust so that the catalytic converters will work properly. If you do not have cats, you should remove your smog pump. When you remove your smog pump, plug the two vacuum lines that go the the two thermactor solenoids and remove the metal pipe going to the back of each head as well as the metal pipe welded to the exhaust and all tubing/valves between those and the pump. You need two bolts to plug the back of the head. I cannot remember what size you need, but if you want I can check mine. If you have any questions, feel free to post again.
