my linea classic mjd which is 10 moths old is having overheating issue. the temp gauge is showing the normal temprature(needle is on middle line) but the engine is taking long time to cool down. (after just 6kms running) the coolant tank, engine bay etc are very hot and i can see vapour drops inside the coolant tank. i dont know whether this is normal or it is a problem. can you folks help me understand if there is something wrong? the driving was on straight road and did not revved high.
