The coolant I have in the car is orange in color. Can I put the green 50/50 stuff in it? The owners manual doesn't say anything about special antifreeze so im a little confused on this. Im sure this question has been asked before but I searched the forum for about a half an hour and couldn't find it. Thanks for your help all

 

The Orange coolant is good for 100K miles....Are you low?

 

Not real low. Its at the bottom line of the overfill. The car only has 25 thousand miles on it. A 2005 6S. Can I top it off with the green 50/50 stuff. My owners manual says to put any ethyl glycol based coolant. I bought some coolant and it says on the coolant bottle "can be mixed with any color antifreeze". Is this true? And my car has not been leaking. I park it in a garage and I would notice if it was. Does it burn some off? Or evaporate? Thanks for your replys in advance
