BMW'S FLAW - Cooling System Overhaul on my FREE TURBO 335i

In today's video we are tackling the cooling system on my 2008 BMW E90 335i! Its got the N54 twin turbo engine. We are replacing the radiator assembly, upper hose, lower hose, heater hose, expansion tank hose, and both wastegate solenoids! If you have an N54 this should hopefully be informative for when you need to tear into your cooling system for repairs.
