Quick back story: back in October I noticed my water pump had a slight leak, so I swapped it out and figured might as well do the thermostat too. Easy swap, no leaks. Cold weather comes in around December and I start letting the jeep warm up in the driveway on those cold morning (20-30s). After about 5 mins of idling I go outside and see this. Once the jeep warms up the leak stops. And after sitting at work all day, with slightly warmer temps (40-50s), it doesn't leak while idling. I pulled the thermostat to check the gasket, didn't notice any issues. On the reinstall I added some RTV around the housing as a second measure. It's not leaking while running because the level in the overflow tank us not dropping. No leaks at all for a few weeks. Current: I parked the jeep Friday night, left the house Saturday morning in the wife's car, temps in the mid 20s. We got home that afternoon, temps in the 50s, jeep hadn't been run in 20 hours and I see this. So what am I doing wrong/missing? What would cause the thermostat housing to leak without the engine being run? I'm using the correct coolant. I can try another thermostat. Is there supposed to be more than just the seal around the thermostat, like a gasket between the mounting surfaces, where I used the RTV?
