My coolant tank is filled up to the correct level before driving off but I've taken a half an hour drive and it is very low and warning light comes on. Once stopped it cools down and the level rises. I've had it checked and theres no leak. Any ideas why it goes low very quickly and how I can sort this out?
Thanks Anthony
Sounds like an air pocket in the cooling system. Take the cap off of the overflow tank and radiator if possible and start the engine and turn the heat on so it'll circulate fully, allow the engine to reach operating temperature and the coolant level should drop as soon as its flushed the air pocket out, top off the system, replace caps and you're good to go.
