I have changed my radiator cap couple of months ago with an original OEM one. The older one had a broken sealant which caused engine over heating.
Now, i have no heating problems but after the engine cools down for 4-8 hours I notice the upper radiator hose gets flatten!
I watched a YouTube video - he was telling the symptoms of a bad radiator cap, in the middle he said "That sucked radiator hose is a good sign of a well sealed coolant circuit!"
So do I have to consider changing the hose or there is another problem to worry about?
