My cherokee has developed an antifreeze leak, I've narrowed down the location, just would like to get some advice. The first pic looks like the tube going into the radiator has it in the threads, but in person and by touching it I didn't see any there.

 

 

is that on the rad cap side of the radiator remember water runs down

 

yes, drivers side.

 

might be the seal, I don't think the hose actually threads on, does it? not sure if you can thread hoses on. I'd try first using a hose clamp and doing it tight around the base of the hose, see if it stops leaking.

 

The smaller metal lines that go into the rad are for the tranny.

I would make sure it isnt leaking from the the upper rad hose, rad cap or the overflow hose that runs to the tank. If it isnt those things on the driver side then you need a new rad

 

bad radiator cap. oveflow bottle hose leaking ,bottom radiator hose loose or side tank gasket leaking

 

^ beat ya

 

I had the overflow leaking a couple months ago, has new clamp, not leaking from overflow or cap. Only trace of fluid from top view is a little bit on top of power steering pump(which is odd).



Dilljeepo-Where would I put this clamp at on the hose?

Will that nut move that appears to be attached to rad? Like maybe unscrew it and put some teflon tape there?

 

Try tightening your upper rad hose.

The hard lines with nuts or clip thingys will leak red/brown tranny fluid if they are leaking

 

So the circled hard line is for tranny?

 

well yes

 

You need another radiator, the cooler fitting is leaking. Just bite the bullet and replace it, problem solved.

 

I had this with my YJ. Drove me nuts trying to find it.

Turned out to leaking from the water pump inner seal, the out of a hidden weep hole under the pump shaft. It then ran down the lower rad hose & onto the top of the lower rad tank. Also onto the frame rail on it's way. I think ethylene glycol has supernatural powers.

 

Ya but what if it's just a little crack in the hose that's on the fitting?
