my radiator hoses after 130,000 miles started seaping coolant out of the hose, the rubber had broken down, so i replaced all those when i rebuild my motor, 0 problems since. even if the coolant tank is nasty, the block and radiator are beautfuly clean.
since you guys think "dem new fangled inventions are bad" along with switching back to green coolant, go ahead and switch your cars to carbs.

I don't think anyone is saying it never causes problems, just that the argument that Green is better b/c sometimes an improperly maintained Dexcool system can get sludge in it is a bit asinine.

after over 10 years of use in MULTIPLE engines in MULTIPLE platforms and vehicles, dex-cool must be junk because gm has invested a ****-ton of time and money in r&d for our cars only to KEEP using it. it's common sense guys, gm has a LOT more money and a LOT more time invested in use of dex-cool, if it sucked they would not use it. how much warranty work would it take to revert back to green coolant? evidently dex-cool hasn't reached that number yet.
GM won't admit to ****. From faulty third gen camaro belts to the column lock problem on the C5's (which costed me over $1,000 to fix). It wouldn't surprise me if they were covering up or ignoring problems with dex-cool.
My 98 vette ate a water pump at 40K miles and it's been having problems with low coolant for the last year.

Basically what I learned is this:
Keep the cap on the radiator
Bleed the system WELL!
change it like normal coolant
keep a CLOSE EYE on the resivor bottle

Hay aren't you the guy that heard the mystery noises when he changed his oil and posted up a bunch of BS on that subject and then caved in at the end of it ..
.. I have 129 K on my engine and water pump ... flushed the dex cool out at 75K and replaced with more dex cool I've had no problems with the cooling system or the anti freeze..it has worked like a champ...as you go through life you will find that nothing is idiot proof..including anti freeze..

No mystery noises. The lifters were louder with 10-40 than with the 0-30 I am using now.

GM recommends mobil 1 5W-30 for corvettes, but it's been proven that many other brands and weights of oil outperform it. why does GM recommend it? they get a kickback from exxon/mobil for it. now, mobil 1 30 weights are losing their full-synthetic status to boot. they're turning into a group III oil
just because GM recommends it doesn't mean it's good for your car. it means they're making MORE MONEY by recommending it.

for your low coolant problem, check your hoses and put in a container of block sealer (before you go saying how itll screw up your coolant system, all cars get it at the factory, and it works)
I've got 116K on the clock and still on the stock water pump and flush my system every year with dex-cool. No problems yet!! (now that i've said this my water pump will go out tomorrow!) 
I guess it's like everything else.....some people have problems and some don't?
