Good Day all,
I've got a 1977 Series 3, with the 2.25 Petrol engine in it. It started running warm a year ago, and since this is not daily driven, I parked it so that I could self diagnose the issues and replace parts as needed. It basically is running to 3/4 of the gauge while idling or fast idling. Current temperature here in DC was 85 deg farenheit last friday. Over the past year I have also replaced other parts on the engine, just ask for additional work if it helps. Engine oil is clean and full. Fuel filter has been changed, fuel used is lead added. I've owned it for 4 years now, and the cooling system ran fine upto 1 year ago.
I started with a new water pump. Pulled the old one off, everything looked fine. Did a couple of flushes. No relief.
Next I replaced heater core, hoses, metal hoses, removed thermostat, temperature sender, head gasket followed by a carb cleaning, and finally the radiator. All replaced parts were followed by system flushes, with no results.
I have replaced everything that could be causing problems. My most recent flush done last friday was still slightly brown.
The next thing I am thinking of checking is timing and the carb fuel mixture. Other than that, I am out of ideas! Please give me some ideas that I can look into. I will also check the temperature of the radiator with an external infrared thermometer today. So after I post you can use this in your thoughts.
Many thanks in advance for your help and knowledge.
