I don't get paid til Friday, N coolant light came on yesterday my coolant light came on yesterday. Would it be ok to fill the reservoir the rest of the way with water? It isn't very low.

Nope, coolant amount equals half of capacity. After flushing there is probably 6 to 7 quarts of water still in there so fill with 2 gallons pure coolant and see.
How long does it take for temperature gauge works after filling it up with antifreeze
