Coolant Service Warning Light
Coolant Warning Light
This is normally the coolant level warning light. 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 pressurised 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.
