Default anti-freeze leak when warming up.

whats up CF?
Like the title says, my 94 cherokee (I-6, 5-speed) leaks antifreeze from the top hose on the radiator only when warming up on really old days. This morning and last monday morning i was letting it idle while i got some coffee for my morning drive. Both days the outside temp was about 5-10 degrees (farenheit). why is it leaking? any help?
Thanks

its leaking like right at the top hose going into the radiator? Have you tried loosening the clam, turning the hose and like pushing it in tighter to the rad then re tightening the clamp?

Id suspect there is a crack in the upper hose or that part of the rad.

Does it stop when it heats up?

It's probably leaking as u drive also.......hole/crack and/or loose clamp(s) makes up about 99.9% of all coolant leaks. When the motor is cold, remove the rad cap and make sure the rad is full to the top.
