I had my coolant fluid exchanged at Lube Express on Friday. Come Saturday my coolant light came on.
I know a lot of people have problems with the floater (thanks to the wonderful "Search" button) but I checked the coolant level up front and it's about an inch below the line that reads "Add Coolant". So I'm sure it's safe to assume that they didn't put enough coolant in when they swapped it...
Now my next questions is what should I top it off with? Distilled water? More coolant?
Also, is it safe to take off that cap even though it reads "DO NOT OPEN HOT"? Can't I just let the engine completely cool down and then open it?
