Fluid leaking at radiator cap
1996 Cherokee 4.0, coolant leaks at radiator cap, I replaced the cap, thermostat, still leaks at the cap, I looked for any kind of visible damage where the cap goes on the radiator, I see nothing, any suggestions??

I had a mystery leak for a little bit form my radiator cap. Turned out that the elbow on the underside of the overflow tank was partially clogged. It allowed some flow, so it was not an issue unless the engine was at full temp for a while. I removed the tank, cleared out the clog with compressed air and my leaking radiator cap problem went away.

Definitely check your overflow tank, line and connection at the rad for clogs.
Also, I bought a new mopar oem cap and still had this problem. I had to bend the metal tabs on the cap slightly to make a tighter fit.

After overhauling my cooling system I had that problem. It could be air in the system. That was my issue. You might need to burp it. Otherwise, there's a clog. Do all the hoses get hot?
