ditto, theres no reason that a behr or nissens shouldn't last many years (i wouldn't bet on a csf, turd!), it came with a behr from bmw and that probably went 10 years or better, id make sure theres not something at work like a leaking head gasket over pressurizing the cooling system or perhaps a outside factor like missing rubber feet (common)
