Default 65mm Supercharger Pulley Failure

Last wednesday while driving home from work, i had the low coolant light come on i kept monitoring temp and tried to make it home. I got within 5 miles of home when temps started climbing pulled over shut engine off. Under hood there was coolant everywhere. It was dark out and couldn't really find the issue so cooled engine down and had towed home.

After refilling coolant 2 gallons of distilled water, i fired it up and easily found coolant spraying from hose on oil cooler. The aftermarket 65mm supercharger pulley from eurocharge broke and one of the pieces had cut two line and cut gash in hood insulation.

I put the stock pulley back on and found similar hose at autozone to use until i can order the correct oil cooler coolant line. Still working on getting air out of the system and need to figure out if running the ic pump dry caused any issues with that pump but other than that the car is back up and running. Saw some interesting temp swings while getting air out of the system.

I have been daily driving car for about 7 months now. The pulley is 7 years old with 14,000 miles on it. Prior to this year, i had only driven on weekend or a friday.

I am going to order proper parts to repair it completely once i figure out what the part numbers are. Here are some photos.
