What is the life expectency of the radiators in Holdens these days. It seems that the aluminium cores are just crap compared to the old copper ones that would last for 20 years. My VS ute radiator started gushing out water at the age of 4 years old so I went down and bought a new aftermarket one and put it in. Anyway that one lasted less that 6 month before it started to leak. I took it back but the radiator shop refused to replace it under waranty because I fitted it myself and they claimed it was caused by the block not being flushed properly and coolant contamination. So anyway I paid out anothor $370 to have them fit another one and flush and fill the system with coolant. Fingers crossed as to how long this one will last.
