Hello Gents,
I have a 47 3100, mostly original ('51 216, radial tires, converted to 12V). The extended restoration notwithstanding, there was opportunity over the holidays to take a cruise of about 60 miles and two things were noticed:
1) The fresh air heater blows cold air, above outside temp, but largely cold air. When I replaced the core during restoration, there was nothing to prevent airflow around the core. Do others with fresh air heaters, particularly those that actually provide heat, have some gasket material between the core and housing to prevent cold air bypassing it? If not, any suggestions on what I might look for? I have confirmed that water is flowing through the core and both inlet and outlet hoses are hot. BTW, I'm still running a 165 stat, but the old heater worked with that same stat (the non-fresh air non-Chevy heater used before the restored fresh air unit was installed).
2) Towards the end of the run, I noticed a squeak at some stops. The squeak, or chirping, was not dependent on the clutch position so the throw-out bearing is not suspected. It's intermittent and I suspect the generator or the water pump. The issue is that I can't isolate them. Any suggestions beyond a mechanics stethoscope?
Thanks in advance for any insights.
Bill
