I think you are talking about the level indication light, if so it's in the header tank and it can get 'gunged-up' but it could need changing.

If this comes on it means that the level of coolant in your radiator is low and needs topping up.


DO NOT OPEN THE RADIATOR CAP WHEN THE ENGINE IS HOT!


The coolant system is pressurized and it could easily release pressure and spray you with boiling coolant. Open the radiator cap only when the engine is cold. The cooling system should only be topped up with either a pre-mixed coolant or with distilled water.

DO NOT use tap water - the mineral deposits in it boil out in the cooling system and calcium gets deposited around the inside of the radiator making it less efficient (which will eventually cause it to fail). It's always best to use pre-mixed coolant. The coolant mixture behaves as an antifreeze in winter as well as a corrosion-inhibitor to stop your engine rusting from the inside out.

Its a very common problem on these cars. The warning light comes on when there is no need to top up the coolant.

As has been said, they get gunged up.

You can take the old one out and clean it, I simply bought a new one,I got it at GSF,it wasnt dear, I think it was about £14.

Either way it a quick and easy fix. Very simple to get it out to either clean or replace.
