hi guys ,the coolant level warning is constantly lit on the dash of my 2.5 cdx estate (w reg facelift ) and yet ,the coolant level is fine , can any of you please help me to rectify this ?

[RobG]

Knackered sensor in coolant tank. Can try pushing sensor up & down to rectify but invariably it`s a new tank from VX as sensor is incorporated within. Around £35

[john r]

thanks for the quick answer , do you mean the header tank ?

[RobG]

Yep

[fiend61]

or you can try unclipping the tank and have a look at the electrical connection in the bottom

or you can undo the plug and and put a link in and short it out

Kinda defeats the object of warning sensors :-?

Your best bet arrange a new sensor, fingers x'd should solve it!

IIRC it's , virtually, impossible to change the sensor. As recommended, change the header tank.

just to let you all know, i had the same problem. the float sensor inside the header had broke free and gave me a constant coolant level warning on the MID. changed header tank from one from scrappy and all sorted now
