TAlKED WITH RADIATOR TECHNICIAN ON 180 STAT.
I talked with a GM engineer about all of us guys switching from 195 to 180 stats. He said that it is not a good idea.
1. It will cause the engine to choke and shoot in more fuel than is needed, clogging up the emmisions system, creating lots of carbon and burning more gas.
2. Normal operating temperature for 3800s is 200-230. The engine needs this temperature to properly burn fuel and pass emmissions tests. No, running the engine this hot does not at all hurt the valves in the engine. He did say that he replaces alot of plastic plenums on these cars. He said that GM is currently replacing newer plastic plenums for free. GM is under a lawsuit for these plastic plenums.

My mechanic said the same thing. I ran a 180 T-Stat in my Jeep for many years without any problems, but I also see the other side of the problem.
My solution: Kept the 190 stat in the Bonne and just did a pro-active maintenance replacement of the Upper Intake with the Dorman unit.

Lower intake temps=better power and less breakdown of oil. I get 29mpg on the freeway at 70mph with my DRILLED 180.
GM has instructions to discourage the use of 180'*. We also have had nobody running 180 have any problems passing emissions.
The 180 is especially important for the 95-99 non-supercharged cars with the failure-prone plastic upper intake. Cooler intake temps may help prevent those problems.
There are literally THOUSANDS of 3800'* out there running the 180 with no problems.
