You drain it out and replace with new.
SEE DEXCOOL CLASSACTION SUIT" I would NOT use it.......$$$$. I HAVE SEEN THE GUNK & BLOWN HEADGASKETS................................$$$$$$$$$$
The antifreeze/water mixture is too weak for the conditions or you have engine oil or trans fluid mixing with it
a 50/50 mixture of correct antifreeze and water, or the already premixed antifreeze. Use ONLY coolant that is designed for GM cars. Do NOT use the green colored or tinted antifreeze since this will gunk up your system and cause real problems like overheating or thermostat issues. I think the correct tint of the antifreeze should be orange, pink, or clear.
Flush your radiator and get that orange antifreeze GUNK outta there! I flushed mine...my mechanic added green antifreeze and all is well....that orange stuff eats and destroys....
yes it is you make blue gunk orange gunk and green gunk hope this works :)
the colors of gunk you get are completely random so there is no special way to get a certain color of gunk.
its best to take it to a gm dealer, the dex-cool antifreeze leaves a lot of gunk make sure to have them flush the entire system.
you cant get rainbow gunk!
I believe it turns milky looking or your oil level keeps going up
Sample sentence: The purpose of antifreeze is to prevent a rigid enclosure from undergoing physical stresses and catastrophic deformation due to the expansion that occurs when water turns to ice.
The gunk slips in your eye when you are very tired.
Get all the color of gunk and mix them together.
