Went to the shop on Ann Rd. to get a coolant flush done. Service tech performed the service while my vehicle was on an incline. I asked if that would affect getting all of the old coolant out and he said "I don't think so"... I then watched as he tried to suck the old coolant out through the overflow tank (I don't have a radiator cap) and I asked how he would get it all out since he is suctioning against a closed system. He said "I'm not really sure, but that he hadn't had any problems in the past"... I then asked how much coolant my vehicle takes. He said around 9qts. I watched as he put in 7L. I asked him why only 7L and he said he didn't know the difference between quarts and liters!...
Very nice guy, but I don't think they know how to actually perform that service. I will NOT being going there for a coolant flush.
