Default coolant

Would it be a good Idea for me to flush the dex cool **** out of my 2000 SE, 2000 SSEi, and 2000 Chevy Camaro with a 3800 V6 and refill all three with regular green coolant?

no, however it would be a good idea to replace it with either prestone Longlife dex compatible, or with mix with any coolant, i prefer the mix with any

I agree. You can flush out the dex, but replace it as Toasty suggested. I also prefer the mixes with any type.

Why not replace it with green?

I had all my dex flushed out and had it replaced with the universal stuff. My car actually runs cooler now.

i believe that the cooling properties of the green are not as efficient and the car will run hotter with green in it

is the prestone dex compatable coolant safer than dex cool?

I had a GM dealer recommend replacing the Dex, I don't know what they put in but its green. Biggest difference is the service interval (Green needs flushed every 30,000 mile they said). The debate is that old Dex is corrosive and ruins a lot of gaskets, and I believe it.

It hasn't run any hotter, but then again it is still winter. The thermostat is the same one and the temp needle still sits the same place. I have never heard the cooling properties are much different, both are a 50/50 water mix (assuming change intervals are observed and corrosion doesn't take over).

The other thing is, the effect of Dex if it gets in the oil pan (not that it ever happens ). They say it is acidic and damages bearings worse than other coolants would. Same thing if the overflow bottle empties and air gets in the system. Dex is worse for some reason when air mixes in.
