If you have around 100K miles, you should probably change the coolant hoses and the two coolant manifold blocks. |
I'm almost positive that the water pump was to blame for the colour of the coolant. The coolant was barely 6 months old. I have almost 200k and I've almost replaced the whole cooling system.
