I'm also sorry for your loss. Before I bought my used Sorento I was aware of this problem through this forum. It was the first thing I checked after purchasing. Mine has the new style. The TSB is still there. I just looked it up and it even has a graphic of the new style vs. the old ribbed style. Below is the thread. You will probaly need a userid and password. Click on TSB...then scroll down until you see the TSB No. Good Luck... perhaps you can find a used engine yourself cheaper. I read somewhere in this forum that the Hyundia XG350L and some Sedona's may use the same engine. Then you could find a shop to install it. Below is the text from the TSB.

Description This bulletin provides information related to Sorento models produced from 6/30/2002~10/3/2004. Some Sorento vehicles may overheat due to small cracks found on the bottom of the coolant reservoir due to repetitive temperature and pressure fluctuations. The new improved coolant tank allows some expansion and contraction found in many pressurized cooling systems.
This bulletin describes the proper service procedure for identifying and replacing the coolant reservoir tank.
