I have a 2004 Jeep Grand Cherokee. While sitting in idle/at a stop, temperature increases a little to just above 210 and the fan is increasingly loud - sounds like it's going to burst out. It also makes a clicking noise as the speed increases. After shutting off the motor and restarting it seems to be fine until it heats up again while sitting.

What could be causing this?

We had a similar problem on our 09 Chevy HHR, it would heat up at long lights and in bad traffic. Sometimes the fan would go into a hi speed mode that was quite loud.

I would suggest going to a Jiffy Lube or similar type of place to have the cooling system flushed. That solved our problem, now it runs below 200 all the time. You definitly don't want to overheat the engine, that could cause a warped cyl. head or worse, and be very expensive. If the flush doesn't work, you might try replacing the thermostat. The water pump is also suspect, but try the cheaper fixes first. Good luck.
