I have a 2000 saturn sl1 with 165k miles. The coolant in it now is the generic green and it's been in there for at least 4 years. I'm going to do a flush and refill. The recommended coolant is dexcool, but I was going to use Zerex G-05 instead. Are there any problems with doing this?
Also, has dexcool cleaned up its act since the sludge issues 10-15 years ago?
