engine running hot

this past weekend i was out mudding, and got tons of mud on my radiator and the trans. cooler. started overheating but i got most of the mud off with water. when i got home i used a pressure washer from a car wash to get the left over mud out, but it still runs hot, although not as much. it's my dd and i have the heat on high to get to work and back. the temp. gauge runs at the 3/4 mark, 210 is the normal. it hasn't gone in the red though.

what are some things i can do or check do get it running normal again? do i need to flush the radiator? should i remove the radiator to make sure no mud is left in it? is that hard to do? i have the 4.0 engine. thanks.

chances are the radiator fins could be clogged with mud. when I did mine i took the radiator out and used a small screw driver to "punch" the fins out. It would also be a good idea to replace your thermostat if you have not done so.
