Today I was taking my Crane HI-6 off my car to sell to a friend and decided to remove the aftermarket gauges on my car. I am in the process of returning my car to mostly stock since it's a daily beater now. Well, I removed the Autometer mechanical water temp gauge bulb from the lower intake. I then reinstalled the stock sending unit. Later I started the car just to pull it back in the garage and noticed the car leaking coolant pretty bad. Well, I discovered a crack has formed from the sending unit hole streching downward to the left. There was no visible crack before I took out the autometer bulb and the thing it mounts to. What would have caused this crack? Is there anyway to fix it without having to take the car apart? :nonono:
