Good job A1 Auto
Very happy with all the parts Ive ordered from you guys.
March 13, 2017
Good product!!
The water pump in my 96 Chevy Tahoe began leaking from the weep hole letting me know it was failing. I ordered a new water pump from 1A Auto.Com. The part was inexpensive (but similar quality to what the shop would have purchased for 3 times as much). It arrived 2 days earlier than expected. I drive 500 miles weekly through the Mojave desert. Since replacing the water pump, I have put about 1500 miles on my truck which turned over 300,000 two weeks ago!! Ive had great experiences with 1A Auto even when I had to return a part that was defective from the manufacturer. The staff is curteous and helpful, and the videos have helped me save major bucks since my first purchase. Ive been recommending 1A Auto to all my friends looking to save on parts for their cars!!

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
What is brand of this part and is it considered to be extra duty?
Cheri J April 1, 2017
We have a few different aftermarket companies build these parts specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle, it is not an "extra duty" part. If you have any further questions, please dont hesitate to ask.
