1994 Dodge Intrepid Blows Radiators

I have a 1994 Dodger Intreprid with the 3.5 ltr engine that for a mysterious reason overheats without warning, although ususally after sitting in traffic. The dealer has not been able to replicate the problem. I have already blown two radiators. The thermostat is new and I let the air out of the valve when I installed the radiators. The car has now 150,000 miles on it. Is there another device that is the culprit? Anyone with a solution? Thanks in advance.

your cooling fans are not turning on, this is a common problem on these cars. Check your fan relay which is in your underhood fuse box; switch it out w/ another relay and see if it kicks on.

You may be right on this. I changed out the high and low temp relays (I noticed that they are all the same regardless of the application) and observed the fans going on. They seem to shut off even though the engine is still hot (according to the gauge). Should I also replace the temp sensor before I buy another radiator?
