Good morning. I have a 2005 S-type V8 that has covered just 46,500 miles. The low coolant warning light comes on at regular intervals but having checked the bottle level I know that it is topped up. Is there any way I can correct this fault. Otherwise car runs perfectly.
Thanks Iain Fraser

Hello

the coolant level sensor on these is prone to sticking so try giving it a poke with a screwdriver to try and rattle it loose

Matt,


Where exactly is the coolant level sensor. All I can see is the top hose and an electrical connection at the bottom of the plastic header tank. There is no sensor inside the header tank.


Thanks

the electrical connector at the bottom is the level sensor


very similar to the image shown here

if yours is the later sensor then there's no moving parts but they often improve once they have been cleaned

this involves removing the sensor and giving it a good squirt of contact cleaner
