Hi, I have a 94 XJ and I was looking for some advice.
I recently started having a pretty major coolant leak but I cannot tell from where.
Here's what I know:
It leaks out while I'm filling from the radiator cap and does so while the vehicle is OFF.
Its not a leak in the radiator, water pump or head gasket as far as I can tell. Maybe a hose?
Any help is appreciated, Thank you.

 

Could easily be a hose, make sure they are all tight. They are all easy to get to and just hose clamps.

 

Anyone's guess no information to go on, make sure hose's aren't cracked, split, broken, loose hose clamp. I would have a close at the lower radiator hose first the top is easy then check the heater hoses.

Weep hole in the water pump?

Where do you see the water coming out at on the ground would tell us a lot.

 

It looks like its coming from the large hose from the radiator to the water pump at the connection point. I tightened it up but its still leaking, Maybe a water pump issue?

Also, if I fill the reservoir, the level doesn't go down when I run the vehicle

 

I just had a top hose blow out on me. Replace the hoses ($12 each) and put some nice Home Depot hose clamps on there and see what happens.

 

Weep hole of the water pump is my educated guess. Look at it. Coming from above the hose connection?

 

I'd try replacing just that hose and get new hose clamps. If it still leaks that would eliminate that as the cause. Since the only other item involved seems to be the water pump that would narrow it down.

 

The only way to find a coolant leak is to follow the leak. The leak will lead you to the source. A flashlight and an inspection mirror are great tools to use.

 

Yes.

 

Update:
Replaced water pump and leaking almost stopped although I forgot to use thread tape on the top hose that screw in and it seems to leak from that, guess I have to dig in again.

 

I've never used thread tape haha, did you tighten it enough? Is that hose cracked?
