What is your question?
The car is always low on coolant and we never see any signs of it on the ground ??? We've had it into the dealer to get it checked, They said they couldn't find anything, It's still doing the same thing. What are they doing wrong? what should I look for? Mike nwlseonmikal@q.com

they are not doing anything wrong, the car is. you need a shop to put a dye in the system to find the leak. it is leaking and will show with dye whether it is in the oil system or external. Roy
The way an automotive shop would locate the leak is by removing the radiator cap and attaching an adapter that screws on in place of the radiator cap. Something that looks like a bicycle pump with a pressure gauge attached to it is used to "pump up" pressure to simulate pressure generated when the cooling system is at operating temperature, the leak is then found sometimes it is obviously leaking from a coolant hose or cracked housing, failed gasket or water pump, sometimes the engines cooling system needs to be inspected from below or inspected using a mirror and flash light. If the coolant loss is still evasive dye can be added to the cooling system that may indicate the source of the leak. A mysterious coolant loss may even be a sign of a head gasket that is not sealing well. If no leak is found I would do a block test to check for the presence of carbon monoxide in the cooling system (blown head gasket).
