Thanks. My mechanic has done a gasket replacement and now it seems ok.

Car: Honda Civic FD4 Problem: Engine overheating at long distance journeys and loss of coolant (about 500ml per 30 minutes drive). Observations: Foam creating in the radiator cap (currently running with only water due to coolant loss). Overflow tank getting full all the time after a drive. There are some foam in the overflow tank too. Occasional white smoke during the morning, cold starts. A leak in the radiator core. The mechanic said it takes a longer than usual time for the thermostat valve to be opened. Both fans work without A/C but takes time to turn on. No other visible external locations for coolant leakage. Things Done: Replaced the radiator. Question: What could be the reason? If it's a blown head gasket (or something else), what is the correct procedure to diagnose/fix it?
