Hi, I have a 99 Chrysler T&C with about 206,000 miles on it. It runs like a top with the exception of getting hot while in traffic with the AC on, especially with both front and rear ACs. I had it in at Firestone for a radiator flush and they left it idle with both units running and it never got hot. They said the computer readout said it needed a catalytic converter. I replaced it. It is still getting hot with the ac running in traffic. I am not sure what to do next. Any suggestions? I love my van. It drives like a limo and I plan to keep it for awhile longer, but with summer coming on I hate have it boiling over.
If it continues to get hot in traffic, you still have something going on. The fans may not be coming on and running properly, there could be a blockage in the cooling system or something as simple as a thermostat that needs replacing because its not opening at the right temp. I would recommend you taking it to a Chrysler Five Star Dealer. The technicians are trained to work on that specific vehicle and will know right where to start. You may want to ask the service manager to drive it for a few days to see if he/she can get it to duplicate the problem. They are great vans! I have one myself. Good luck to you.

The catalytic converter really is for emission issues and would not have much to do with an overheating problem. I would suggest bringing the vehicle to a qualified technician that can examine the entire cooling system including the thermostat, the radiator itself, the fan, the hoses and the quality of the coolant that is in the system. Just to make a note, it is normal for a vehicle to run at a higher temperature during the summer, in traffic with accessories on. However, if the gauge is nearing the red zone or actually overheating, there would obviously be a problem.
