I recently took my 2004 Corolla for a 30K change of fluids (oil, manual transmission and coolant).
What I noticed when I picked it up is that they put green coolant fluid even though it came with red fluid from the factory.
When I went back to the service desk to ask them why they did that, they told me that that is how they keep track to see if the coolant fluid has been changed or not.
He said that factory is red, then the first fluid change is green, and then they go back to red so that it shows as purple. He assured me that the red and the green fluids are the same.
Is this true? I was under the impression that red and green fluids should not be mixed.
Thanks all for your help
