‘12 Jk radiator petcock leaking
Hi
I replaced the thermostat yesterday and during the drain process the petcock popped out. I managed to get it back in but it won’t seal now and drips when system pressure builds up.
I realize the petcock isn’t supposed to come out and am wondering if I am looking at a new radiator now or should I try to hunt down a new o ring. I live rurally so I can’t afford to play around with it too long; if I have pooched the radiator I would just as soon get on with it than spend a couple days finding an o ring only to find out I broke something internally.
thanks.

I've totally removed my petc0ck before with no issues. There's nothing on the inside right there that you would have broken in doing so. If it were me, I'd 1) verify the o-ring is clean, and/or 2) replace the o-ring. Honestly, our petcocks are so bad you could probably pull it out and take care of biz without too much leaking out. Did you feel like you needed to drain the radiator to replace the thermostat? You don't lose much coolant in that process.

The petcock from the dealer isn't crazy expensive. I had a similar issue after a coolant change and it turns out the o-ring wasn't quite fully seated. I now have a spare petcock just in case. My leak was barely a dribble but enough to where I'd see it on the pavement.

Rip in a 6 year old o-ring isn't too surprising.....what is surprising is factory radiator is still going strong after 6 years.

I think I would have used some epoxy and just sealed that petc0ck drain off. After trying to pull that thing out to drain my radiator, I learned my lesson. It's just easier and better to disconnect the bottom hose if you need to drain the coolant.
