coolant change?
Why is it nessary to change the coolant in a ls1? I have never changed the coolant in any of my vehicles. From what I've read coolant doesn't wear out, so why change it 
Or is the dex-cool different? Is it good enough to just drain the radiator and refill or do I need to drain the block too? My car has 9300 miles on it but it's a 2000.
I did plan on changing the break fluid this spring so, can I just open the bleaders one wheel at a time and pump it out that way?
Thanks for the help

Dex-cool doesn't need to be changed as often as conventional coolant, only at 5 yrs or 50,000 miles, but all coolant should be changed periodically at regular intervals. Even if the engine seems to be running fine temp-wise, there are corrosion inhibitors that prevent damage internally to the block, heads, water pump and radiator, regardless of whether the parts are iron or aluminum. I have seen the damage that can be done on cars that the owners did not properly maintain. I can also personally attest to all, do not use Dex-cool in vehicles where it isn't specifically suggested to do so. I had a radiator damaged by using it in my street rod and had to flush everything including the engine block.
