I recently got a blinking temp light in my '84 camper.  I topped off
the overflow tank with no effect.

I had earlier noticed a drip under the front end, but I didn't know
how serious it might turn out.

Had the camper carried on a flatbed to Peninsula Automotive in
Campbell, California, about 6 miles from my home.  They found and
replaced a leaking heater valve, and all is good now.

I guess the heater valve wasn't one of the parts replaced when
GoWesty installed a whole new system about four years ago.  Steel
pipes, new radiator, new hoses, but also, if I understand, the other
newer stuff that was original to later model years.

Eventually, I guess, I'll find all the bits that they left in place.
