My 1992 used to have that problem until a faulty radiator fan was replaced. In that case, the fan was mostly working, but wasn't coming on reliably when it was supposed to. The problem was finally identified when the fan shorted out and blew its fuse, resulting in overheating (hot summer day in traffic). By the way-- if the car in question has air conditioning, try turning that on when the engine is running hot. That will activate the A/C radiator fan, and (assuming that fan is working normally) you might see a rapid decrease in engine temp. Such an observation would point towards a problem with the fan temperature switch or the auxillary fan itself. John
