I was in the driveway today installing my Sinister coolant filter kit and noticed something that could have ruined my weekend...
They neglected to crimp the ferrule on the heater hose tee fitting and I just barely caught it before tightening everything down. I would have likely blown the hose off and who knows what else.
I called them up and they offered to send me a new one of course. I had already cut my hose and moved my coolant valve so I didn't want to wait until tommorrow ( I have to get to work somehow). Luckily a 5/8" Pex crimper (for plumbing) will put a perfect crimp on these.
Moral of the story... CHECK THE FITTINGS on this kit before you start this project. Sinister isn't the only one using crimped hoses so this applies to all brands.
