My dad has a problem with his EB I low water warning light. The light on the dash is flashing even with a full header tank??

He tested the switch on the header tank whjen full and it readed 180OHMS which is the same as what my car reads so he suspects the switch not to be faulty??? anyone have any idea how to fix it?

You will probably find that the sensor is all gummed up, take it out and clean it

Is it flashing or glowing constantly? I thought that they glowed constantly, if it's flashing perhaps its an electrical fault somewhere...

You sure it's not the windscreen washer bottle one?

i have the same problem at the moment......the sender unit has aplastic float level and it has a pin hole in it and it fills up with water and sink....which shows up as the tank being low when its not....there,s only one catch they want $75.00 for a new one

couldnt you drain it and plug the hole up with silicone or something though? stuff $75.00 if you can get away with it, although, $75.00 is better than $600+ for a head gasket

When the light flashes, it indicates that the sensor input is floating. ie, not connected. You may have a build up of crap on the plugs or it may have a break in the wiring. The light should only glow when its detecting low coolant.

Brent79 is right here, try check the wire, even better make sure it is plugged in properly. A continuses flash (with no warning sound) indecates that the sensor has been unplugged (or elect. fault).

If the float is sinking (have had this before) then the light will stay on with the warning sound.
