Hello,
I am completely dumbfounded and I have hit a dead end on my cooling
problem with my '55 Ply 6 cyl. Essentially, the motor overheats as indicated
by the meter. The meter hits the highest temperature even before the
thermostat opens. Consequently, I have worked as systematically as I was able
to try to eliminate possible problems but still, the meter indicates
overheating before the thermostat opens:
These are things I have done or observed:
1. changed the thermostat three times from 180 to 160 (tested both
thermostats separately in hot water and both open)
2. checked the timing
3. replaced the radiator with another one
4. replaced the water distribution tube with a brass type
5. replaced the water pump with a NAPA brand
6. replaced the temp gauge
7. replaced the temp sensor twice-the current one is brand new from a '57
Chrysler
8. replaced the wire sending unit twice with wires of different gauges
(#14 and #16)
9. checked oil pressure --normal
11. done reverse flushing
12. checked the water temperature with a glass and metallic thermometers
and both indicate 180 degrees as the water circulates when the thermostat
opens.
As the motors runs, water circulates and both hoses are hot but by this
time the meter indicator is out of range and have to turn the engine off.
Hope someone has some other ideas or maybe knows what's going on.
Thanks
