Our 88 Vanagon runs real good now that we replaced the transmission, but it
tends to overheat while stuck in traffic or at a long signal light.  The
temperature gauge goes up considerably.  We have found the only way to get
the temp down again is to turn on the heater, which causes a lot of
discomfort during the summer months.  Any ideas on how to correct this
problem?

Thanks,
