      Need help diagnosing the dreaded overheating syndrome on my Westy.
     Have searched long and hard on the list archives and have got many
     good suggestions and fixes but still at a loss. Running the van for an
     hour or so at highway speeds, the guage registers to the left of the
     vertical and the red light is off. If you slow down for any reason the
     temp goes up. After driving at lower speeds or idling for a while ,
     the red light goes on, and the temp guage goes all the way to the
     right. After a while it will go back down and then back up after
     another while. At this point the guage and light are erratic, even at
     highway speeds. After the van sits for a while and cools down, it will
     again go for an hour or so with the guage registering just to the left
     of vertical and the light off. We have replaced the coolant level
     sensor, flushed the cooling system, replaced the thermostat, and bled
     the system. We also bypassed the rear heater core , as it was leaking
     and appeared to be the source of air in the system and replaced the
     blleder valve in the engine comparment as it was crumbling apart.
     Sorry for posting this common prob. but we really are at our wits end
     and any and all advise would be greatly appreciated.
     Thanks
