DMan1198 Insufficient lubrication on install is often the cause of o-ring failure when it looks like that. I generally use petroleum jelly on any o-ring I install.

drwaggs Not sure how it happened, but bad O-ring right after or during install. Easily fixed with new ring.

98whitelightnin I replaced the oring on mine too and my leak quit. Find the biggest oring that will fit and get a handful of them

Cajunberry I had the same issue after doing my delete and found the issue to be a bad o-ring. I’d pull the connection out and look at that first. Found a new o-ring in a o-ring kit from harbor freight tool. Hope this helps

Delete Coolant Leak

Finally deleted, but I have a leak. See pic. I've read other threads that lead to a Glacier Diesel Heater Hose adapter. Will that work here or are there better fits?
