Default leaking somethin???

well I went wheelin this evenin and when I got home I noticed a wet spot under the front passenger tire about the size of a basketball. After investigating it looks like its comin from the plastic jug under the hood where you put antifreeze...how do I fix this?

You need to replace the jug. Sounds like you cracked it somehow.

I just took the jug out and it dosent look like theres any holes or cracks...its not even drippin from the jug. I took the radiator cap off and antifreeze started overflowin out the cap. I got it soaked up to where there was no antifreeze down about an inch below the cap and it quickly filled right back up and started comin out again...any ideas?

It must be coming out of the overflow on the bottle. Was it warm when you took the cap off?

Try bleeding the system to see if that helps.

Park the Jeep so the highest point is the rad cap. Make sure its cool, take the rad cap off. Run the jeep up to operating temp and fill it up. That should remove any air trapped in the system. It might be time for a new rad cap, a bad one would cause boil over.

Idk about bleeding but to burp the system you run the engine til it warms up then shut it off and turn the radiator cap slightly and close it . Repeat a few times that helps get the air out.

a stuck/clogged thermostat can cause the problem you have as well. your coolant got hot, and just went to the weakest point, which is the overflow in the coolant jug.

what i don't get, is how the antifreeze is moving in a cold engine (unless it's running when you opened the radiator cap)?

time for a radiator flush?

Yeah the engine was off and it was cold for sure...

so you guys think a good flush and a new rad cap might do the trick or am I gonna need a new thermostat aswell?

A T-stat is only ten dollars, cheap insurance.
