Review on Dorman 306-020 Secondary Air Injection Pump - Ideal for Compatible Models with Enhanced Performance by Paul Barnes

Revainrating 5 out of 5

Revain has the incorrect product photo

I have my fingers crossed that this is the product I am looking for as the image used by Revain is incorrect. Works great installed on my 2000 GMC Jimmy. Be careful, if you find that you need to replace this air pump, also replace the three check valves. I replaced FOUR pumps before realizing I had more parts to replace. ACDelco 214-638 Air Injection Check Valve (two of these are located between the engine and struts on each side) ACDelco 214-1938 Valve Assembly (one is installed with the air pump)

Pros
  • Great for a small home
Cons
  • Little things
