In September I changed out the radiator on my 2005 Liberty w/ 3.7. When I did the radiator, I removed the thermostat to help in draining the block. I changed out the rad and put on the old thermostat with the old o-ring. No leaks at all.
I haven't driven my jeep much since then. 3 days ago I started driving it because we got dumped on with snow. It's also been quite cold; -36'C (no wind) when I started her up today. This morning I noticed the heat from the heater (gauge didn't fluctuate) was fluctuating. I checked the coolant and it was low and it was leaking from the thermostat housing. So, appear to have a thermostat leak.
Think a new o-ring and thermostat will fix this? In september, I thought I could get away with reusing the original o-ring because it looked fine. Maybe I was wrong on thinking it could be reused.
FYI: In September I did break off the lower thermostat housing bolt. I had to put in a longer bolt and put a nut on it. I can't see this causing an issue but I thought I better mention it.
