I have a very pampered 2005 tundra sr5 4.6 and have used this sight over the years to keep it in top condition . The question I have has been avoided on every post I have read . My secondary air pump that has just under 150000 miles has the tell tell high pitched sound of I am done. Now Hewett is ready to jump in with the answer I have read on so many other threads. For reasons of my own not interested in bypass kits. So has any one have had any luck with NAPA pump made by DORMAN part 306010. So far my pump has just started to get loud and no other problems no codes . Not driving truck till I repair it. Please again not interested in bypass any thing. Any advice on other brand that may be better. Do not be sucked in by part at dealer I worked at large chain part store and local Toyota chevy ford dodge ram etc etc called me 10 times a day for parts they would sale under there part # and sale for well past list cost.

 

Very few people here post about getting an aftermarket. It’s typically either an expensive OEM replacement or the bypass to save money.

Good luck though. Someone may post about it or something similar.

If you do decide to get it, let us know if it fails within a year or two. I’m sure others would like to know your experience.

 

Welcome from NY.

 

Gonna be honest. OEM got you here 19 years later. Cheap route would be to pull your pumps and clean them up and see if they still have any service life left. If not (likely) I would replace with OEM. Find a better deal from a Toyota parts supplier online.

 

Welcome from LA (Lower Alabama)!

 

Any one ever have any luck cleaning pumps. Have not removed intake yet to see one other than pictures.

 

Any one have part # for the two rubber hoses that are on the oil filter cooler. Not having any luck finding them on line.

 

Just so you know, it is rare for anyone to take a second look at an intro thread. You'll get more and better responses if you post these questions in the appropriate forums:

If the pumps are still functioning, remove them and inspent them.

I'm betting you just have build up on the fins.

These pumps are not anything special. Clean them or if you find broke fins, replace the fan assembly. I'm betting once you get it apart, you will see the issue causing the noise.

Just like any diagnostic steps, you have to take it apart.

Please report back with what you find.
