I would like in the future on my Pk Ave to find a local shop that has a coolant recirculating machine, that uses the Prestone or would allow me to use my own Prestone coolant.
These machines use demineralized water mixes in most cases.
This would fully flush the existing system, to be spotlessly clean again.
I like that. The last two GM dealerships I worked at had those recirculating (recycle?) machines - similar to the R134 machine'* operation. Of course, they were strictly OEM DexCool.
