I am planning to service my 2002 Saturn SL2’s coolant. It has Dexcool right now. I didn’t know people hated the stuff. About 90% of people in Saturn forums seem to have already switched to “the green stuff”.
I already bought the Dexcool but I am debating whether I should return them and make a switch to green too. I have read somewhere that you can’t determine the chemistry of a coolant by just the color, so I don’t really know what do they mean by green exactly.
Some people are telling me to use the “mixable” type of coolant when making the switch. I am assuming this is the universal coolant? HOAT? Some say a tiny bit of Dexcool left is not a problem.
What is the correct procedure to replace the Dexcool with other coolant? I don’t have access to a garden hose.
