Gross coolant!
My 2000 Camaro is having some issues with the coolant. Last winter my heat stopped working, and the mechanic said my coolant was so gunked up they had to chisel away at the opening with a screwdriver! The jerks at the dealership said I needed a new heat pump, radiator, etc. etc. $1200 worth of repairs! I took it to a more reputable mechanic who flushed the thing about 6 times and got the heat working again. A few months ago, the heat stopped working again but since it was summer I let it go. Well, I just had it back in the shop to get flushed several more times, and the mechanic said it would probably need to be flushed a few more times in a few months to clear all the crap out. He said the dexcool coolant tends to gunk up.
So is the multiple flushings the right thing to do? Can the gunking up be prevented?

Its not supposed to gunk up if you keep it maintained properly. Maybe dexcool was not used at some point and regular anti freeze was used instead. That could have caused some of the parts to corrode and be a reason for the problem. Was distilled water also used to mix with the Dexcool? Its never supposed to be mixed with regular water.

Dexcool is the orange one. The engine is supposed to only have dexcool in it though. I don't know all the detrimental effects of using the regular green ethylene glycol but you are definitely not supposed to because it can corrode some of the parts in your motor. I think its because of the aluminum block.

Dexcool is extended life antifreeze. As long as you completely flush the system out you can switch to the green, which is what I have done. Dexcool will leave a ton of sediment in the overflow bottle. I replaced my overflow bottle and flushed out the entire cooling system. There are NO adverse effects in running the green.

the only catch is you must flush the old dexcool out of there very well

correct!!!! dexcool is the worst coolent!!! although some people disagree with what i said because they support the factory recomendations, but the dex cool stuff really starts to corrode the radiator and later as the coolent gets old it turns in to a dark brown **** color with chunks of brown **** that clog up the radiator. the first thing i did when i bought my camaro is flush the cooling system and fill it with the green stuff 10x better
