Parts fit as described. It was great getting the parts shipped to my house.
Part fit perfectly. Easy assembly, great price, fast shipping. Speedy, effortless checkout.
I put my new water pump on and it working amazing
This was an afterthought purchase since I had to have the water pump replaced. I figured I might just as well go ahead and replace the thermo, too. It fit well and worked great!
Fit perfectly, came quickly. Nice to have air back!
I ordered this part based on how soon I could receive it and it actually came two days before it was due and it was an actual GM part that fit. Sometimes time is not the major reason but in this case it was very important as to when the part arrived.
