Default coolant

hey guys.......i have a 95 vert 6speed...when i first got it the coolant was brown......took it to my friends garage and we flushed it out with the machine......i wasn't sure if dex cool was factory fill in 95 or 96 ....but it looked like it already had the green stuff, so we just used the green stuff........ran it all summer, stayed around 198-215but the oil ran about 230.should i go back to the dex cool or just stay with the green stuff?........thanks guys

Chances are the brown color was the stop-leak tablets that GM puts in from factory. Or it may have been added later.

Your coolant seems like a reasonable temperature.
I am not sure about your oil temp.

The oil temp is fine, too. What is your concern about changing the coolant? If you DO make a change, make sure you do a VERY thorough flush, including pulling the block plugs, and/or knock sensors. With all the bad press on Dex Cool, lately, I wouldn't be in a rush to make a change. The good old green stuff has served us well for decades.

RACE ON!!!
