Re: Flex fan
I had the original flex fan on my XB GT when i purchased it. A month down the track giving it a boot full at around 4000 rpm, one of the blades decided to part company with the rest of the fan. It wasn't pretty. Said blade put a hole in the bonnet, innner guard and slashed A/C hose. The remaining part of the fan wasn't happy with this, deciding it wanted to say hello to the radiator along with half the water pump.
Traced the problem back to a tiny pulley fitted to the water pump that was making the fan spin at 1,000,000 RPM.
Fitted a new Clutch fan and correct size water pump pulley after that and it has been as good as gold.
