I ordered this part along with a new water pump for my truck. Both items arrived within 2- days which was fantastic and they were both exact replacement parts that came complete with gaskets. Installation was a breeze and my truck was back on the road the same day. Great dealing with Parts Geek which saved me $$ compared to any of the local auto parts stores in my area. I couldn't be happier nor more satisfied !!! - Pete Booth
