1 more question boys and girls..
1997 Grandprix GT 4 door, 3800 Series II.
What is the most effective way you have found to flush the cooling system of its old coolant.
The reason I ask is because the guy I bought the car from was a parts jockey at the GM dealership, and the car has Dex-Cool in it from a previous flush and fill.
I'm going to be replacing the coolant elbows at the same time, as per my previous post.
What's your best way/technique? I will be doing this at work. For those of you who dont know me well (basically all of you..lol) I am a farm equipment mechanic, and have access to most everything. I will be refilling with some off the shelf green coolant.
Thanks,
Jay
