Hi guys, so my Jeep is my first vehicle, so I'm learning on the fly, and I had a quick question. There's a tube coming off the top of my coolant reserve/overflow bottle that leads down into my right front wheel well and I'm wondering if anyone can tell me what that is. I narrowly avoided going head on with a (noun removed) who thought it'd be a good idea to pass someone on a blind corner and the right side of my Jeep dropped into a deep ditch. Everything looks okay, but it felt like a jolt on the vehicle and i'd never looked and thus never seen this tube before. I'm just worried that it's supposed to be attached to something. Or is it just a vent of some sort? It's a 1997 ZJ Limited, 6-cylinder. Any ideas?

Look and see if you have a tube from the outside of the radiator neck over to the coolant overflow reservoir. At least that's the way my 96 4.0 is set up and the tube connects to the upper side of the reservoir. There's no tube coming out of the very top of the reservoir or cap and maybe that's what RedZj is referring to.
My 1995 4.0 has the hose leading from the radiator filler neck under the radiator cap over to a plastic molded in tube on the front of the overflow tank in the right rear of the engine bay. The molded in tube appears to go to the bottom of the overflow tank. There is a similar molded in tube on the backside of the overflow tank which appears to be able to take fluid from the top of the overflow tank and route it downward. It does not have a tube connected to it, even though it appears to have a place for a piece of tubing to slide over the bottom inch or so of it. It may not even be open at the bottom of the tube. I would have expected for the overflow tank to have an overflow tube of its own leading down below the chassis.
FWIW and other years definitely may be different.
- 1995 4.0L ZJ NP249 - mostly stock for now
- 2008 Jeep Patriot 5 speed Manual 4X4 - for sale, great car, would keep it if I could.

Awesome, guys. Thank you. Everything looks intact and the Jeep got me to work fine this morning. Thing saved my life. If I'd been driving a little car I would've been head first into the ditch. Jeep was just all like, 'yay! I love off-roading!'
