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 hipower...I am planning on replacing the o-ring on Saturday and will put Teflon tape on the threads also. I just hope the sight glass isn't cracked.
UPDATE: I replaced the o-ring in the pressure tank. Everything went smooth with removing the plastic sight glass(not cracked). Old o-ring was cracked in multiple places(I'm surprised it hadn't leaked sooner).
I had already purchased the multiple pack of O-rings from Harbor Freight so it was easy fitting the proper size to the sight glass. Basically a 5 minute job sucking out some coolant with hand pump, replacing o-ring and sight glass, and putting coolant back in tank. Thanks everyone for all the good suggestions.
