Hi,

If you had to refill it after three days, you must have a leak. It has to be going somewhere. Have you noticed any indications of a leak? For example, are there any wet spots where it's parked or steam coming from the engine compartment?

If there are no indications of a leak, I need you to read through this link that explains what to look for if there is a possible head gasket-related issue. Let me know if anything indicated mirrors what you find or experience.

Let me know what you find.

Take care,

Joe
