Called David's and asked if they did coolant flush and they said yes. They did a coolant flush but did not do reservoir tank. Called them and they said normally they would suggest it be replaced, and unsure why it was not suggested to us and to bring it in and he would take a look. We brought it in and was told he could not clean it and it should be replaced. When we Called and dropped off our truck we let them know of the brown muddy substance in out coolant. If you want a coolant flush I would recommend going somewhere else as they do not do the reservoir tank which would be considered a complete coolant flush. What it looked like when be took it in and got it back.
We performed the service that you requested based on someone else recommendation. Had we known that you wanted the staining removed from your coolant reservoir, we would have recommended replacing the part, as it is impossible to clean the internal stains from a transparent coolant reservoir. What we did do, is preventative maintenance to help prevent future failures of an already severely contaminated system.
