bad inferno Member 130 Member For: 18y 8m 4d Posted 01/07/17 10:37 AM Share Posted 01/07/17 10:37 AM Just picked up a 2012 turbo FG which is ~140,000 klm. I have no clue on when the coolant had been changed however have done a nulon clean/flush and nulon refill, replaced the coolant reservoir and its kept clean for the last month without seeing any contaminants. So my concern is now if I squeeze the top radiator hose or any of the heater hoses I can feel the buildup of oxidation/corrosion inside the hose crack away. Should I be concerned ? I was thinking about replacing the hoses however assume its also in all the engine block galleries anyway. Link to comment Share on other sites More sharing options...
