Low coolant light keeps flashing

add coolant let it run til the thermostat opens to see where the level is at if you need to add more or not

Low coolant

Check it when cold,not just
the overflow tank ,the remove the coolant
cap & check

May want to check the a/c housing drain also

My guess would be the low coolant sensor which could be in the overflow tank.

CHECK COOLANT OVERFLOW JUG IF EMPTY ADD MORE COOLANT UNTIL COOLANT LEVEL STAY AT FULL COLD MARK.LONG AS COOLANT LEVEL OVERFLOW EMPTY KEEP COOLANT AT COLD FULL MARK.IF COOLANT OVERFLOW JUG YOUR RADIATOR COOLANT LEVEL LOW.

The coolant light tells you are low of coolant, so have you checked to make sure that you have enough coolant - between the two marks on the radiator overflow reservoir? If not add and then keep a close eye on the ground under your car for the next few days to make sure that you are not leaking any out.

And if you haven't replaced your pressure cap on your radiator in several years, you might want to consider that.

ADD COOLANT IN THE COOLANT OVERFLOW JUG UNTIL COOLANT LEVEL STOP DROPPING AND COOLANT LEVEL STAY AT THE FULL COLD MARK.PLACE COOLANT OVERFLOW JUG CAP BACK ON JUG.CRANK VECHICLE UNTIL ENGINE START WARMING UP. STOP ENGINE WAIT FOR A WHILE UNTIL COOLANT COOL DOWN TO KEEP FROM GETTING SCALDED. USE A LARGE RAG OVER THE OVERFLOW JUG CAP OPEN OVERFLOW JUG CAP A LITTLE AT A TIME REMOVE OVERJUG CAP CHECK COOLANT LEVEL ADD MORE. COOLANT IN THE OVERFLOW JUG.THEN START VECHICLE AGAIN.LET ENGINE IDLE UNTIL TOP RADIATOR GET HOT.THEN THERMOSTAT WILL BE OPEN.WHILE ENGINE IDLING WATCH THE TEMPERATURE GAUGE IN VECHICLE IF TEMPERATURE GAUGE START CLIMBING IN THE HOT ZONE.TURN OFF VECHICLE LET IT SET A WHILE THEN USE LARGE RAG REMOVE OVERFLOW JUG CAP.ADD MORE COOLANT, PLACE CAP BACK ON START VECHICLE AGAIN KEEP DOING THIS PROCEDURE UNTIL TEMPERATURE STOP CLIMBING HOT ZONE.AND WHEN COOLANT LEVEL STOP DROPPING IN THE COOLANT OVERFLOW JUG.AIR IS OUT THE SYSTEM, BUT KEEP COOLANT LEVEL IN THE COOLANT OVERFLOW JUG AT THE FULL COLD MARK.DONT OVERFILL.DONT LET COOLANT OVERFLOW JUG RUN DRY IF SO AIR WILL ENTER COOLANT SYSTEM BECAUSE COOLANT LEVEL WILL BE LOW ENGINE WILL START OVERHEATING.

These days that little light is triggered by the level of the coolant in the overflow reservoir. Assumption being you should keep an eye on that. So I would check the coolant reservoir, generally an opaque plastic jug connected to the radiator by a hose, for a switch or sensor. I would start by removing the whole thing and giving it a good rinse in case that has never been done, and replace that sensor which could well be a dealer item.

Well, top off the overflow tank to the marks as indicated based on engine temperature, and see if it happens again, and note how long it took for it to happen.

might need to have you coolant flushed, possible that there isnt enough coolant in the overflow container

I belive they didn't reset the oil light timer. I belive the sequence is 1. key on (not acc with engine off)
2. step on the brake pedal 5 times within 10 seconds. 3. key off. 4. start car. 5. check if the light went out. you may have to try it a few times to get it.
