Flushed and filled the coolant in my truck over the weekend. What came out of the bottom of the overflow bottle looked like putting a frog in a blender or frappe. So thats all good and well and the truck runs as happily as it ever has but i find that now it makes a whirring sound thats only really noticeable when slowing to a stop (it will slow as I slow and stop when I do). I definitely got coolant EVERYWHERE when i pulled the lower rad hose. Also my driver side wheel occasionally squeaks from a stop but will stop at speed or when the brakes are applied. Ideas?
