Message cooling. To get to the electromagnet that operates the clutch, I removed the radiator for easier access. While it looked pretty clean from the engine side, there was quite a bit of plant material and tiny pebbles embeded on the winward side. Make sure yours is clean as well as the condenser. I cleaned and straightened mine with detergent, a garden hose and tweezers. Be patient, it is delicate.

There is also the issue of the fan clutch. That bugger is filler with a goo that when it heats up, reduces the fan speed. These are often the cause of overheating. While you are at it look at your fan; mine was ready to throw a blade, it had several cracks around the hub.
