New here. Jeep Wrangler owner since 2003. Rig now has 127k miles on it so she's getting older.
Flushed and replaced coolant system this past summer. Recently, during the worst cold spell to hit Ohio (-4) I lost heat when I stopped moving while at a traffic light. As soon as I got moving again the heat returned. I checked coolant level and found the reservoir filled to the max. The level would return to normal and the cycle would repeat itself every day. I replaced thermostat and the same thing happened. I also noticed that there was no pressure after running engine and removing (carefully) radiator cap.
I replaced radiator cap and that took care of the problem. Heat is fine, temperature holds, everything seemed fine for a few days. Then, I noticed coolant was disappearing and now I'm smelling burning coolant.
I'm assuming a blown head gasket. Oil is fine just burning coolant in the engine compartment (lots of it). It's 10 today and I'm just adding coolant to get me to the weekend.
Do you guys agree that it's a blown head gasket? Is there anything else I can look at? How much will it cost to repair? Is it worth repairing or should I look at having a rebuilt engine installed instead?
My rig is a 6 cyl Rubicon and has many add ons. I love this thing and don't want to get rid of her.
Thanks in advance
