Low coolant light stays on until system heats


Your overflow tank(aka coolant recovery reservoir) is low on coolant. The coolant expands when warm and raises the level in the tank, which turns off your light. Top off the reservoir (when cool) to the "Full Cold" line. If you have to keep adding on a regular basis, then you have a leak somewhere in your cooling system, could even be the reservoir itself.

I just bought a 2003 Toyota Echo and when I start the car up, the blue "low engine coolant" light stays on for about a minute before shutting off. I've added coolant, so I know it is full,...


Make sure there is no air in the system, take the radiator cap off and let the engine idle for half an hour, as the air comes out the coolant will go low, ad more coolant and then close the cap on also make sure the resevour bottle is at its mark.

I have 2 problems 1. my low coolent light keeps flashing an staying on its full of fluid an 2. good battery in car changed altinator an now the battery wont hold a charge what could the problem be


The switch in the coolant tank that turns the light on can stick due to contamination from old coolant.Replace this switch,or leave it disconnected.If your battery drains overnight,there is likely a draw,possibly trunk ot glove box light on.If the problem started when the alternator was replaced,it could be a shorted diode in the alternator.

Low coolant light stays on. added coolant and is still on.


Did you add the fluid to the Radiator or the Overflow container. The radiator should be full and the overflow container should have a mark on it for full. Make sure both are full. If they are then you most likely have a bad sensor that you will need to locate and replace.
