I'm going nuts with the exact same problem on my 70k Roadmaster Wagon. I can see the fan kicks on, no loose fan clutch, replaced the thermostat and radiator cap and still keeps happening.
Has anyone else heard or better yet fixed this problem.
I'm really not sure its not overheating or if its the gauge wandering. No white smoke or loss of fluid, so I'm pretty sure its not a head gasket either.
I could change a handful of sensors but it looks like thats a shotgun approach.
Thanks for the help.
