Hello! We have a 92 240GL, and an 84 240TI and with the influx of hot weather and the need for a/c [which they both have and usually work well with no issues] we have had both overheat. Overheating = the temp on the internal guages registered almost in the red. We're curious, as this happened on both 240's in the same day. And both of these lovely beastly tanks have never done this. And the 84 has a new water pump as well.
