Halfway up mountain, coolant boiling!

Don't you hate when something like this happens?

My family and I were 30 minutes up a mountain trail today when we stopped to look at the view. I noticed a bubbling sound, and discovered it was my coolant in the reserve tank, boiling.

Now do we continue, taking the chance that we'll overheat farther up the mountain and be stuck? No, we turned around back to civilization instead, keeping my family safe.

Got a new radiator cap on the way back, and hope this solves the issue.

just had a similar problem on a rocky trail. jeep temp shot up fast, warning light came on, opened hood and antifreeze boiling out the over flow. luckily another guy had a gallon of water to refill after it cooled off. turned heat on and got out of the trail. fan clutch went out that's what caused my overheating.

Just curious..... Are you running an Automatic Trans ????? If so it cools thru the Radiator coolant....I suggest you have the biggest auto Transmission cooler installed....
That will take the added heat away from the radiator....

I hold you personally responsible for me having a dream about my Jeep overheating while on a trail. Read your post last night before going to bed... wont do that again!
Hope all is better with your Jeep!

My 03 standard was doing the same thing. Replaced my radiator cap, problem solved. Make sure it is 15 psi rated.

15? The replacement called for an 18psi I believe. I got the CST 7018 cap. Will that be an issue?

Yes, it's the 42RLE. Good point. I will look at the options for coolers.
