So even your statement is only 68.89 percent probability of being correct.... or only partly fabricated !!!
83 multiplied by .83 = 68.89

Can someone explain why moisture contamination would be higher in the winter?


Kindly explain how adding new, clean fluid to existing fluid causes "contamination."

snow buildup on the body of the car? heat/cool cycles?



I don't think the new fluid is the contaminant in this case, I believe the OP is talking about leaving old fluid and flushing only some of it, lets the older fluid hold onto it's moisture that it has accumulated, and any bits that are left in the front system, contaminate the rear new fluid...

It snows, it melts, there is moisture. It snows, it melts, there is moisture. It snows, it melts, there is moisture. It snows, it melts, there is moisture. It snows, it melts, there is moisture. It snows, it melts, there is moisture. It snows, it melts, there is moisture. It snows, it melts, there is moisture. Cycle continues.


He changed it in August. System is has picked up moisture for 10 months. Changing half the fluid still leaves the other half with fluid still contaminated with moisture, which will mix with the new fluid.

The extra fluid to bleed the fronts would be what, $6?
