yes it worth it. You may not feel or notice a difference but there is one. Do it and don't look back. FYI the 94.5 and 95 MY came stock with a 203 stat! then they changed for some dumb reason!

I think the change had to do with emissions. I think with a hotter running engine NOX increases.

The parts counter persons I have been dealing with locally are of limited intelligence in that if it doesn't appear on their computer they don't know what to do. So I am thinking I should be safe in simply requesting a new thermostat for a 1995 250PSD, even though mine is a 97. Right?

Itfox is correct the 203 and 195 are physically different due to a change in the water pump casting. If you are doing a waterpump you can use the 95 pump and t-stat if you wanted to. Just make sure you can source a 203 stat for it. I know the last Napa stat I bought for my 95 (2 Years ago) was a 203
