Hi,

I am suffering VERY slow coolant loss. Late year the dealer had the car for two days and replaced a suspect hose in the V. I am not super technical FYI. Anyway it went back recently and they couldn't find any cause for the loss which is still happening. Anyone suffered this?

Thanks in advance.

Chris.

change the header tank cap first.

^^^^^^^^^^as Jimbo said, if after run pump has been checked

if they only changed a hose, could still be the after run pump

Best to get someone who has a pressure tester to check it. Will be much easier, and quicker to identify

When the weather gets colder, it's common to get a few minor leaks, check all hoses and connections, and sometimes its just the cold itself making the level seem lower.

Replaced the coolant pressure cap and coolant level is holding steady. Thanks for your help!
