my first one blew due to overheating because the clutch on my fan broke...replaced that with an electric fan setup, and a new gasket, my stupid ass stocker radiator cracked...leaked coolant, overheated again. that was my second head gasket...replaced gasket, and got a new radiator. That was in the course of 6 months, Im now on backorder list for the tripple layer metal one from www.nizzx.com, its destined to doooooom! goodluck
