Bmw cooling issues

[e46jase]

i have a small coolant leak i suspect one of the hoses or a crack in the expansion tank cant find it by normal inspection ima have to strip cooling system one weekend

cant you see dried coolant somewhere?

check the sides of the expansion tank and around the thermostat housings as a first point of call.
