I have recently changed the expansion tank as it split down side, common fault,The car got extremely warm due to lack of water.
I have now filled up the system and bled it several times,car jacked up and on the flat.
I cannot get rid of the orange low water level light warning light.
I have swapped it over with the washer sensor which is of the same type. No change.
Bottom hose is cold when the temp gauge is reading normal operating temp.
Heater in car works ok.
I have also noticed radiator fan not switching on? Is this related?
Also had the gas check done with the green/blue fluid to rule out cylinder head issues. (what a relief)
next step probably to check functionality of theromstat?
Water pump costly to swap both with no definite diagnostic?
Has anyone else experienced the same issue.
Thankyou in advance.
