Today I had to pull the radiator due to leaking in the top. I took it to the radiator shop for repair but it still leaked after it was repaired. I ordered a replacement radiator this evening...
Also I pulled the "special" 261 thermostat housing and put in a 235 single action housing and thermostat. I hope this will make the cooling system reliable on the road. Picture link below:
