Coolant leaking question for you guys. I've got a 98 classic that I drove a hour round trip. About half mile from my house I started to lose coolant didn't notice anything until I got out and my wheels were soaked. Popped the hood and it's coming someone from the front drivers side. I don't believe there are any freeze plugs up there (hopefully) and the upper rad house seems in good condition. It's pretty much right under the airbox and the bottom edge of the radiator.
TL;DR coolant leak driver front. What is?

From what your explaining that's directly where the lower rad hose goes to the rad. Right under the airbox.

Could be power steering fluid or brake fluid over there if you aren't sure of the leak.

Yeah I just did mine last week. I didn't say It couldn't be the water pump. But I've had 6 of these Cherokees and the lower and upper rad hoses always come loose.

T stat and water pump are dry. I'm probably going to say upper or lower rad hose. I'll put it up in the air tomorrow and check
And it's definitely coolant. Green fluid sitting in the engine bay and about a half mile long coolant stain in my neighborhood

It most likely is lower rad hose, but it's easier to give a list of possibilities off the bat to be checked than it is to play catch up. There's a reason I said lower hose first.
Anyway, I replaced that stupid stock clamp with a 1.75" hose clamp to make it easier in the future.

Pull the clamp off the lower hose on the radiator and drain all the fluid out. Flush it out from the top to empty the rad and clean it out semi decently... Push the jeep to dry clean ground and pull the hose from the water pump. Then replace and fill her up. I bet you $10 that's where the leak is coming from... Might be dry rotted or just a pinhole leak...
