Site glass for coolant tank on 1997 Country Coach

Thanks guys....

you might try Northwest RV supply. I just bought a new transmission temperature gauge from them and they have a sight glass. Not sure it will fit your coach. Worth a shot

Mine was leaking about a year ago and I just replaced the rubber o-ring that fits around the sight glass. The plastic glass wasn't cracked, so the new o-ring took care of the problem.

I bought a large assortment of O-rings at Harbor Freight for a couple of bucks.

Thanks will check...
