Small Coolant Leak
I have a 1993 JGC with the V8 engine. Recently it has begun to leak a fluid
out of the radiator cap. It only leaks fluid after the engine has warmed
up, and is cooling down. I was able to follow the trickle of coolant to the
radiator cap. At first I thought that the cap was bad, so I replaced it
with a new one from Checker Autoparts. That didn't seem to work, so my next
thought was that it is building up too much pressure. The only problem is
that I can't think of a reason why it would build up extra pressure. Is
this a possible sign that my water pump or radiator is dying? Or, does
anybody have another idea.
The only thing that has changed on my car was that I had the oil and
transmission fluid changed before I noticed this problem. Also, I had a new
radiator put in 2 years ago, and a new fan put in last year.

Check that the hose from the radiator to the recovery bottle isn't plugged.

Re: Small Coolant Leak
Your cap has 2 seals. One at the rad and one at the top lip of the
filler neck. This is so the fluid that comes out of the rad as it heats
up is contained at the top lip and sent to the overflow bottle. Then
when it cools down, the top lip seal holds so it sucks fluid back to the
rad.
I would suspect either a deformed top lip on the rad or a leak at the
overflow tube or a leak a the neck to rad joint.
