Sight glass in coolant tank leaking
Coolant is slowly running out at the base of the sight glass on my overflow tank. I noticed that the sight glass screws into the tank. Making sure it was tight didn't stop the leak. Has anyone had to...

Thanks for all the good comments and suggestions. I do have a standard pressure cap on the tank. I didn't want to remove the sight glass and have an exposed hole until I was relatively sure that I can get a new o-ring at an auto parts store. I don't think the sight glass is cracked, but one poster said that they are readily available at truck shops, so I will check into that also. Thanks for all the good info!
