Problem with Coolant Light

hI,

Yesterday i've changed the coolant bottle with coolant sensor, but the light stills blinking. What can be the problem?... Anyother sensor?

Please help!

Thanks

On what car?

97 Jetta GLX VR6

I think is the expansion tank (coolant tank) cap?... can be?

The bottle came with a new sensor, or did you swap the sensor onto the new bottle?

I changed the bottle with a new sensor.... because the bottle came with a new sensor.... then the coolant light still blinking... i think is the bottle cap... i will change it... any suggestions?

Try overfilling to see if that makes the light go out. It may be a bad sensor. It could also be a wiring problem....

I've overfilled and the results was the same... i go to change the coolant tank cap and check the wires.

Thanks
