I'm finally going to dive into the decades of pathetic heating in my P6B (1970). Would appreciate any and all ideas of diagnosing and solutions. </div>

Background: my heater has been anemic for 30 years; yet I have a friend with a 3500S whose heater is hotter than hades. </div>
<div style="color: rgb(0, 0, 0); font-family: "Comic Sans MS",Chalkboard,cursive; font-size: 12pt;">
I completely rebuilt my engine with correct thermostat. All hoses were replaced, and the radiator re-cored (but the heat was just as anemic before it was re-cored). </div>

The blower fan has always seemed just as anemic as the heat---sooooooooooo, could it really be that if I rebuilt/replaced the blower fan that I would suddenly have adequate heat? </div>

The only other important piece of information I can think of, is that during the engine rebuild, I never had the small heater core pressure tested (that being said, when I had the engine radiator re-cored there was no indication of any blockage after years
of use-----the re-coring was done to successfully decrease engine operating temperature)</div>
