I’ve been troubleshooting what I thought was a hot-running motor.   It’s mid-summer in the mid-Atlantic, and I have a triple-black Tiger, so not the ideal scenario to run cool.   The car’s been running between 210 and 220 at 50 mph on level roads.  It doesn’t get a lot of miles, so I thought the radiator might need a flush.  I changed the thermostat (180deg) at the same time.   Same temps.  I pulled out an infrared thermometer and with the car idling, the temp gauge was indicating ~ 215 while the infrared thermometer was reading 183 when pointed at the water outlet and F4B manifold.   I ordered a new temp sending unit from Rick – any other suggestions?   

  

Thanks as always,
