So if I install 180 tstats in both cars, what'* the expected temp swing then going to be?
Please comment if you have a supercharged bonnie and have installed a 180 tstat.

With the 180, your spikes should rarely cross the 200 mark. Mine is drilled now, and I NEVER cross the 200 mark any more. I usually run about 185 with the drilled 180, and about 5-10 hotter with the stock 180. Remember, the 180 OPENS at 180. This doesn't mean you'll run a consistent 180.

Since I had that TOILET WATER flushed from my system the other day, the temp swings and peaks more and a tad higher, respectively.

The 180 is going in soon. I don't think I'll drill it first. I'll try it and see what happens.
If it needs more work, "I BE DRILLIN' IT!"

If that'* who I think it is, he'* DA MAN! Looks like he'* ready to put a couple holes in a bus driver'* thermostat

I had over heating with air cond on in 100deg. freeway driving.Flush out with prestone super , still has light build up of hard water inside tank of radiator. Can I use something like LIME AWAY,CLR,poolacid/muriatic,icemachine/phosfuric acid diluted with lots of distiled water .what one would be safe enough for a fast flush that doesn't hurt water pump, sensors,hoses. has anyone used citrus acid cleaners? any chemists out there? I had one person recomend muriatic/pool acid diluted ,this sounds too strong.

I often mutter things under my breath when I'm driving the BUS (gotta make sure the PA system is off...) and that comment about "English" is one of them.
That'* too funny!
