Anyone have more info on GM replacing the plenums for free due to lawsuit??

if putting in a 180 stat actually reduces the chance of an air plenum failure on a K motor, why doesn't GM put out a service bulletin or do a recall......too much money...don't want to admit they have a problem.......making more money selling plenums??

My '93 still has its original (what, 200º, is it?) in there at 112K and it'* been fine. Kept up to date on cooling system flushing now, too.

One interesting thing I noticed was that after I got the A/C fixed last summer, the running temperature _dropped_ slightly, and that includes driving through the winter when the compressor obviously was not operating and I assume the cooling fans weren't, either. The termperature gauge is now clearly a notch or two below the center mark (200º on the gauge, if I remember right) most of the time, whereas before, when the A/C was out and the HVAC display would do its two-minute Hey-I've-Got-an-Error-Code blinking every time I started the car, the gauge spent most of its time slightly higher on the scale, creeping well above 200º whenever I sat too long at a stoplight.

So I'm wondering if there'* some input into the ECM that changes its behavior if the Freon is low, or otherwise if the HVAC is reporting a problem, which results in a slightly higher running temperature. I know it doesn't seem like there should be, but my car has definitely been running a little cooler since the A/C was repaired, and the cooling system had not been touched at that time, or since.

i have a 180 stat but i havent gone through emissions yet so will see

i have a 195..............and i've hit over 325 at half a tank.............

SORRY OFF TOPIC

what???
i hit about 180 at half tank and about 280 to 300 a tank regardless if city of highway driving

Maybe our engines get better MPG as they get higher miles on them?
Just breaking in at 150k.

I've got whatever was in there when I bought it (pwner was a car guy, but the wife drove it, so most likely 195). Mine doesn't get above 195. EVER. It could be 95* out, and i'm stuck on 494, and i'm still 195. I may go down to a 180 for the performance build, but other then that, i see no point. If it was that much of a benefit, GM would have done the colder stat from the factory.

Mine too, I don't get that kind of milage, a full tank will only give me 400 at most. I have the 195 on my 1993.

Hey JR! My Trip Odometer is dead, If press to reset I can see the numbers moving a little bit , it is in 000 and they won't move doesn' matter how long or how fast I drive.
Any idea how to repair this? Is the Trip Odometer connected to a cable or something?

Doesn't the AC compressor kick on whenever the climate control is set to defrost? Thought I'd heard they did that so that the compressor wouldn't seize up in the winter due to lack of use.
