Anyone?
Could you possibly have some trapped air in
the system? Try removing one of the heater hoses and listen for a gurgle. Then
also unloosen your radiator cap to the first detent, without removing it. It
should be loose enough for air to escape but not be able to be pulled off.
Next start your motor and let it warm uip. Keep an eye on temp guage and as
temperature increases, rev engine a couple of times every 5 minutes or so ,
but just rev to about 1000 rpm for a couple of seconds at a time, to ensure
that thermostat is opening up. Let engine idle for 15 to 20 minutes, then shut
off. Wait about 10 minutes to see if any coolant rises up and out of radiator
or whether you can hear any gurgling. Repeat the above a second time. Do all
of the above with your heater valve wide open to xtreme heat. Hopefully this
may solve your problem.

Seasons Greetings, Imperialists!
Here's a question regarding the heater in my '59.
Having replaced the core this summer I was expected to be toasty all winter
in my Crown, but now the following is happening: When I first start
out in the morning, the heater works great, but when I hit the freeway, it
grows colder and colder until I stop again, then it warms up. If I
stop completely for a few minutes, it sometimes works fine the rest of the
day, then again it works until I hit a high speed.
Is the heater valve the culprit? That's all I can
think of--sluggish flow or something? Are these obtainable without
difficulty if that's the prob? I'll appreciate any opinions as I have
never had anything like this happen before.
Happy Holidays,
