Themis is probably a more general engine question rather than specific to my Jeep. But I’m not well versed in troubleshooting cooling system problems. I have A 2005 Wrangler with a 4.0. Recently I started loosing coolant. I noticed it one day when my temp was up slightly but it never got “hot”. My first diagnosis was a leaky radiator cap. Running or while shut off it was leaking slowly into the vent tube. Replaced that. Refilled the water and things seem to have been fine for a couple weeks. Now suddenly I’m low on coolant again. Filled it again and within a couple days it’s a bit low. I see absolutely no leakage anywhere so I’m assuming it may be a head gasket. I did check the oil and all is well with it so I know it’s not leaking into the crankcase at all. What I’m after here is to see if you all agree with what I’m thinking and if so what’s a good way to check to see if I am in fact loosing it through the head gasket before I spend the time repairing that. Any suggestions are greatly appreciated.
