Radiator caps need to hold pressure. Failure to hold that pressure can result in overheating. A failing radiator cap will not always leak or lose coolant.
A replacement is about $5.00 They are often overlooked.
Replace it (or at least pressure test it) just to be SURE you are not chasing your tail.
Should be a 16 pound and get one without a lever/release. That lever is not needed and is just another point for potential failure in the future.

Howdy scjeep!,
Just a suggestion...... seein as you do a lot of off road from what you are saying, it is very possible the vanes in your rad and condenser ar all plugged up with dried up crud and bugs and road gunk.....
this reduces the efficency of the rad and condenser. get a pressure washer and let the rad and condenser have it! you would be surprised.
Also, i agree with some other posts here with regard to how old the radiator is, if its original it probably has so much crap built up inside it.
only way to tell though is to take it out,,, and heft it. just so you know, a new radiator when u are holding it in your hands weighs next to nothing. While the old radiator when you heft it will weigh considerably more, meaning its blocked up somewheres.
the removal of your radiator is a not too long of a job, and if you want you could also pressure wash the vanes better with the rad iator out of the vehicle.
just my two cents and good luck with it!!!

Remove 170* T stat and install 195* T stat.
Your problem is that the lower temp T stat is to low and staying open all the time. This is letting the coolant flow right threw the rad and back in to the block. It is not giving the coolant the time it needs in the rad to remove the heat it took out of the block.
Had this same problem my self with a 318 about 10 years back after parts guy gave me the wrong temp T stat. Replaced it with correct one and problem solved!
