I got very weird thing that my coolant is lost when the engine is cooled down. I added it full before drive and when I shut down the car and check the coolant level immediately nothing changed, but after like a few hours when the engine is cooled down, the coolant in reservior is gone. what could be the problem? BTW I just changed my radiator which is from radiatorbarn couple days ago. Some guy suggested me to buy a new cap, but I really didn't find any leaking around cap!
Someone can help me out?
