• Q: How to Replace the Secondary Air Injection Pump on 2001 Cadillac Catera?

  A: The first task for Secondary Air Injection Pump replacement requires you to lift the vehicle up. Untwist the hose clamp securing the air pump supply hose followed by detaching the Air Hose from the air pump. Repurpose the Horn assembly while marking where the air pump sits inside the bracket and then remove the bracket along with frame nuts that secure the pump. Disconnect the electrical connector of the air pump and proceed to take the air pump assembly out of the vehicle. During disassembly procedures disconnect the assembly bracket wiring harness plug together with the hose clamp and air intake hose from the bracket. You should remove the meter assembly air pump bracket bolts before extracting the air pump from the secondary air pump dampening ring. The initial position of the secondary air pump should be aligned before securing it to the secondary air pump dampening ring while torquing air pump to bracket bolts at 10 n.m (89 lb in). Fasten the air intake hose using hose clamps followed by connecting its wires to the assembly bracket. Reinstall the air pump assembly into the vehicle while tightening the air pump bracket to frame nuts until they reach 12 n.m (106 lb in). Reinstall the Horn assembly together with connecting the electrical connector to the air pump and hose attachment until securing the clamp before letting the vehicle down.
