My radiator cracked and was replaced in March. A month later, it was running through coolant and I replaced the radiator cap. Now (July) it still runs hot occasionally. Any ideas?
Also, my air conditioning is no longer running cold. I have never had anything done to the a/c system other than replacing the belt. The car is 6 years old. Will I need to replace the a/c or is there something simpler and cheaper to do?
I highly recommend you take your car to a shop ASAP to diagnose why the engine is running hot. Whatever the problem is, it could get a lot worse in a split second and then your engine could over heat and be destroyed. The technicians need to run some tests to find out why!
As far as your A/C goes, again, you need to have a trained technician have your car right in front of them to diagnose the problem. Could be as simple as a small leak, could be that your compressor is broken. You won*t know until you have it properly diagnosed.
All My Best,

One other thing you could check for the "running hot" problem is the thermostat. If it*s not opening properly it can cause the engine to run hot. Make sure the radiator fans are working properly and if all that is good, a complete flush of the system is not a bad idea.
If the a/c is not cold it could be related to the running hot condition of the vehicle. Since the condenser is right next to the radiator, it may not be able to cool down if there is a hot engine problem. It may also just need a charge of refrigerant.
Both of these problems are best diagnosed by taking the vehicle to an ASE certified shop or dealership to have them looked at. Hope this helps.
