Dash Heat

[john r. lebetski]

You may "knock something loose" in the core but of it fails it was ready to fail anyway. System is pressurized and closing "send " off still
presssurizes the core with system pressure, like air in a balloon presses equally in all directions. If heat still poor you can disconnect the heater
hoses and backflush with garden hose. Just be careful as tap pressure is like 55-65 and system is 9psi so start slowly until you have good flow to
limit pressure rise.

For what it's worth, I did a test in my 1978 Transmode on Tuesday. I
turned on the engine, and within a couple of minutes I had warm air. In
10 minutes with the fan on high, the temperature in the midsection went
from 30 degrees to 52. Hope that helps.

We have a 78 Royale and our dash heat works great. I did install an
electric ball valve in the water line to it so I could shut it off
100% in the summer. These ball valves work great and are inexpensive,
I have a switch on the dash to open and close it.

Now that's a find. Lots of other places one could be used-not necessarily in a GMC.
