dexcool or ethlyn glycol
im getting ready to flush my radiator engine. but i have heard alot of bad stuff about the dexcool, like it eats away at your hoses and it clumps, i also heard of a recall on a small suv(cant remember name) using dexcool. do u guys think it would be ok to switch.

While it is ethylene glycol based antifreeze, the concern with mixing comes from the fact that there are very different chemical inhibitor packages in use. Most leading technologies will work very well when used as intended, typically at 50% in good quality water.
If the coolants become mixed with DexcoolŽ, however, one study showed a possible aluminum corrosion problem in certain situations. The other question is a concern for dilution of the protection packages. At what mix is the there too little of either inhibitor to protect the engine? As a precaution, both GM and Caterpillar instruct that contaminated systems must be maintained as if they contained only conventional coolant.

But it is ethylene glycol.....
From the Texaco/Havoline website:
From the Texaco/Havoline website:
Havoline Extended Life Anti-Freeze/Coolant DEX-COOL is manufactured from ethylene glycol and a highly effective long term corrosion inhibitor package based on carboxylate technology. This inhibitor system eliminates the need for silicates, phosphates, borates, nitrites, nitrates and amine additives traditionally used for this purpose. The replacement of these inhibitors is significant for water pump life because many of these conventional inhibitors have been shown to be abrasive to water pump seals. In comparison field tests with conventional coolants in taxi fleets, Havoline Extended Life Anti-Freeze / Coolant DEX-COOL significantly reduced the need to replace water pumps during the 100,000 mile test.

*100% biodegradable in its pure unused form
*Nitrite-, borate-, phosphate-, nitrate- and amine-free

I ran a mix of Dexcool and conventional coolant in my wife's high milage daily driven Grand am for over a year. This car was driven 80 miles one way to work.
I've also ran a mix of Dexcool, conventional coolant and stop leak for a few months. It now has 157K miles and hasn't had any cooling issues related to coolant. Just a hole rubbed in the radiator from an idiot technician that didnt reinstall it correctly after a trans flush. Thus the stop leak and that stuff is still stoppping the leak!
Proof that everything on the internet isn't truth, the x-drilled rotor myth. I can find several "articles" saying they run cooler which it total crap.
