I went to firestone last month and they did a coolant flush, i was hoping the degas would cleaned out to, but it didn't.
​​​​​Do you guys think i could take the bottom hose of the degas let it drain and spray the inside good and clean off the walls. Put the hose back on and fill with 50/50 would be ok? Thanks

 

What's a degas?

 

He's talking about the radiator overflow bottle.
