This genuine ACDelco water pump kit is the GM-recommended solution for restoring cooling system integrity on 3.0L LM2 Duramax-equipped trucks and SUVs.

With the outdated vent system in my motorhome, these new vents should really do the trick.

Best price, quick shipping, packed well. Exactly what I wanted.

Super grateful you had the part. I searched other location and nobody had it in stock. You saved my bacon after the freezing temps. Will definitely shop here again and very fast delivery!

I was pretty happy with the service. I ordered the part on a Sunday afternoon and paid $9.99 for 2 day delivery and it arrived on Friday 5 days later so not sure I got what I paid for in that regard.

The expierience has been great, would purchase from them again.

Fast, fast, fast. No issues. No worries.

Super price, fast checkout.

Great job
