Hello all, I have researched and searched the forums for answers to my running warm condition, to no avail.
Background Info for consideration:
-1954 235
-overhauled in 2007 now has about 7,000 miles on the motor. (runs very strong)
-"rv cam" I believe a 261 cam
-Dual carbs (Webers) Langdon setup
-Dual fenton exhaust
-Electronic ignition Langdon (advanced 13 degrees at idle as instructed)
-new 4 core radiator running 50/50 water green coolant
-new 165 thermostat
-7 lbs radiator cap
-Electric fan in front of condenser
-Old air products AC
-12v alternator
I added an electric Tach and temperature gauge hidden in glove box. The temperature runs anywhere from 200-220 degrees. The probe is located in the original placement. I changed the radiator, thermostat and hoses with no decrease in temperature.
This morning I timed how long the motor takes to get the motor up to temperature. The Outside air temperature was about 90 degrees. With the motor at idle it took the motor about 10 minutes to heat up to 200ish degrees.
When I sped the motor up (2000 rpms) the temperature would decrease slightly (10 degrees).
Does anyone have an idea of what could be causing the motor to run hot?
What should I check next? water pump?
I read on the forums about a possible head gasket failure, allowing exhaust to heat the water. What indication would I see, beyond the excess temperature, before pulling the head?
Thanks in advanced!!
